2006 Acura sat at an interesting point in the brand’s history, balancing luxury-sport sedan refinement with sharper compact performance models. In the same model year, Acura buyers could be looking at an RL luxury flagship, an RSX sport compact, a TL sport sedan, or a TSX sedan with a lighter, more agile character. Tire sizing varies significantly across all four 2006 Acura models, with seven distinct radial sizes and no single fitment shared across the full range. The practical first step is to identify your exact model, then confirm whether you need a standard metric radial size or the RL’s model-specific metric-millimeter fitment before narrowing down product choices.
Which Tire Size Is Right for Your 2006 Acura
Seven tire sizes apply across 2006 Acura vehicles, and they vary by model rather than being shared across the full lineup. The main decision is first confirming the correct model and rim diameter, since the RSX, TL, TSX, and RL do not all use the same wheel size or tire format. Understanding those differences before choosing a product saves time and helps match the tire to the right car.
Year(s): 2006|Fit(s): RL|Construction: Radial|Rim: 17-in rim
245/50R17 is a metric radial size with a 245 millimeter section width, a 50-series aspect ratio, and fitment for a 17-inch wheel. This RL-specific size uses radial construction; product details and sidewall-style variety are not expanded here in the current selection. It suits buyers who have a 2006 Acura RL on its 17-inch wheel setup and want to stay with the standard modern metric radial format used on that model.
Year(s): 2006|Fit(s): RL|Construction: Radial|Rim: 460 mm rim
245-680R460 is a metric radial format used on the 2006 Acura RL, with a 245 millimeter section width, an overall diameter of 680 millimeters, and fitment for a 460 millimeter wheel. This size is specific to certain RL applications rather than universal across 2006 Acura models, and product details can vary substantially because the wheel itself is different from the more common 17-inch setup. It is the right choice only for RL owners whose car is equipped with the matching 460 millimeter wheel system and who have confirmed that unusual rim specification before moving forward.
Year(s): 2006|Fit(s): RSX|Construction: Radial|Rim: 16 in
205/55R16 is a metric radial size with a 205 millimeter section width, a 55-series aspect ratio, and a 16-inch rim diameter. It is available from BFGoodrich and Michelin in blackwall form, with tubeless marking present on at least one product and speed ratings that vary by product, including W up to 168 mph and Y up to 186 mph. This RSX-specific size is a sensible choice for owners keeping the car on its 16-inch wheel package and wanting a modern radial tire with a straightforward blackwall appearance.
Year(s): 2006|Fit(s): RSX|Construction: Radial|Rim: 17 in
215/45R17 is a metric radial size with a 215 millimeter section width, a 45-series aspect ratio, and fitment for a 17-inch wheel. BFGoodrich offers this size in blackwall form, and the available products carry W speed ratings with a 168 mph ceiling. This size is specific to 2006 Acura RSX fitments using a 17-inch wheel and will appeal to owners who want the lower-profile radial look and response associated with that wheel package.
Year(s): 2006|Fit(s): RSX|Construction: Radial|Rim: 17 in
225/45R17 is a metric radial size with a 225 millimeter section width, a 45-series aspect ratio, and a 17-inch rim diameter. It is available from BFGoodrich and Nitto in blackwall form, and the current products in this size carry W speed ratings with a 168 mph ceiling. This is another RSX-specific 17-inch fitment, and it suits owners who have confirmed that wider RSX wheel-and-tire package before choosing among the available radial options.
Year(s): 2006|Fit(s): TL|Construction: Radial|Rim: 17 in
235/45R17 is a metric radial size with a 235 millimeter section width, a 45-series aspect ratio, and fitment for a 17-inch wheel. BFGoodrich and Nitto offer this size in blackwall form, and the available products carry W speed ratings with a 168 mph ceiling. This size is specific to the 2006 Acura TL and fits the model’s sport-sedan role well for owners who want to keep the factory-style 17-inch radial profile.
Year(s): 2006|Fit(s): TSX|Construction: Radial|Rim: 17 in
215/50R17 is a metric radial size with a 215 millimeter section width, a 50-series aspect ratio, and a 17-inch rim diameter. BFGoodrich covers this size in blackwall form, and the available products carry W speed ratings with a 168 mph ceiling. This TSX-specific fitment is the right path for owners keeping a 2006 Acura TSX on its correct 17-inch setup and wanting a modern radial with original-style overall proportions.
Four 2006 Acura models are covered here: RL, RSX, TL, and TSX. Tire size does not stay the same across the lineup, so identifying the exact model matters before choosing a tire, and the RL adds an especially important distinction because it can use either a conventional 17-inch metric size or a metric-millimeter fitment. Select a model below to see model-specific fitment history and the tires that apply to it.
2006 Acura RL
The 2006 Acura RL was Acura’s flagship luxury sedan, aimed at buyers who wanted upscale comfort with all-weather capability and a more technical feel than many rivals. Its tires mount either on a 17-inch wheel with 245/50R17 sizing or on a model-specific 460 millimeter wheel when equipped with 245-680R460 fitment, so RL owners should verify the wheel itself before moving ahead.
The 2006 Acura RSX carried Acura’s sporty compact hatchback formula into one of the last years of the model, and it remains popular with enthusiasts because of its sharp handling and tuner appeal. RSX fitments span both 16-inch and 17-inch wheels, so the correct size depends on the specific wheel package on the car rather than year and make alone.
The 2006 Acura TL was a defining Acura sport sedan of the era, known for its crisp styling and a strong balance of comfort and responsive road manners. Its tire fitment is more straightforward than the RSX or RL, using a 17-inch wheel with 235/45R17 sizing for the model covered here.
The 2006 Acura TSX sat below the TL in the lineup and earned a following for its tighter dimensions, rev-happy character, and European-influenced balance. The covered fitment uses a 17-inch wheel with 215/50R17 sizing, giving TSX owners a single clear starting point before comparing tire series.
Twenty products are available across seven tire sizes for 2006 Acura vehicles. 205/55R16 comes from BFGoodrich and Michelin in radial blackwall form; 215/45R17, 215/50R17, 225/45R17, and 235/45R17 are covered by BFGoodrich or Nitto radial blackwalls. Confirm your exact size first, since speed ratings and tubeless markings can vary between products within the same size.
These FAQs sort out the model-by-model tire differences across 2006 Acura vehicles, including the RL’s unusual metric-millimeter fitment, RSX wheel-package size changes, available blackwall radial choices, and the upkeep concerns that matter on low-mileage modern collector cars.
Size Basics & Fitment
What tire sizes fit 2006 Acura vehicles?
2006 Acura vehicles use seven sizes across four model lines. The RL uses either 245/50R17 on a 17-inch wheel or 245-680R460 on a 460 millimeter wheel. The RSX uses 205/55R16, 215/45R17, or 225/45R17 depending on wheel package, while the TL uses 235/45R17 and the TSX uses 215/50R17. Where product dimensions are available, rim-width ranges run from 5.5 to 7.5 inches for 205/55R16, 7.0 to 8.0 inches for 215/45R17, 7.0 to 10.0 inches across 225/45R17 products, 7.5 to 9.0 inches for 235/45R17, and 6.0 to 7.5 inches for 215/50R17.
That means year and make alone are not enough for a correct choice on a 2006 Acura. The first checkpoint is the exact model, and the second is the wheel diameter actually on the car. RSX owners especially should verify whether the car has 16-inch or 17-inch wheels, while RL owners need to confirm whether they have a conventional 17-inch setup or the less common 460 millimeter wheel. Once those basics are confirmed, the size choice becomes much easier and you can compare products within the correct fitment instead of across the whole Acura lineup.
What does 245-680R460 mean on a 2006 Acura tire?
On a 2006 Acura, 245-680R460 is a radial metric-millimeter size rather than the more familiar inch-rim format. The 245 refers to section width in millimeters, 680 refers to overall tire diameter in millimeters, and 460 refers to the wheel diameter in millimeters. It is an RL-specific fitment and does not interchange directly with the other Acura sizes used elsewhere in the lineup.
The practical takeaway is that the wheel matters just as much as the tire on this fitment. A 460 millimeter wheel is not the same as a 17-inch wheel, even though the dimensions seem close at a glance, so the wrong assumption can derail a replacement search quickly. If your 2006 Acura RL has this size, confirm the wheel marking before ordering and do not substitute a standard 17-inch tire unless the car has been converted to the matching 17-inch wheel package.
Do all 2006 Acura models use the same tire size?
No, 2006 Acura models do not share one common tire size. The RL, RSX, TL, and TSX each use their own fitments, and the RSX alone spans three different sizes depending on wheel package. The RL is also unusual because it can use either a conventional 17-inch metric radial size or a 460 millimeter radial size tied to a specific wheel system.
That difference matters because a tire that fits one 2006 Acura model may be completely wrong for another even if the cars look similar in photos. A TL owner should not start with RSX sizes, and an RL owner should not assume the car uses a standard inch-based wheel. The safest approach is to identify the exact model first, then confirm the existing tire size on the car or the wheel diameter before comparing brands, speed ratings, and other product details.
Buying the Right Tire
What sidewall styles are available for 2006 Acura tires?
The current 2006 Acura tire selection centers on blackwall radial tires across the available product-backed sizes. That includes 205/55R16, 215/45R17, 225/45R17, 235/45R17, and 215/50R17, all offered in blackwall form. No whitewall or specialty collector-style sidewall treatment appears in the available range for these Acura fitments, which suits the clean, modern factory appearance Acura used in this era.
For most owners, that makes sidewall choice simpler than it would be on an older collector car. The more important appearance decision is choosing a size that matches the correct wheel package and preserves the intended stance of the RL, RSX, TL, or TSX. If you are restoring a particularly original car, blackwall radial construction aligns with the period character of a mid-2000s Acura far better than any vintage-style sidewall treatment, even though exact brand and series choice will still affect tread pattern and visual detail.
What brands make tires for 2006 Acura vehicles?
BFGoodrich covers most of the supported 2006 Acura sizes, with Michelin appearing in 205/55R16 and Nitto appearing in 225/45R17 and 235/45R17. For the RSX’s 205/55R16 size, BFGoodrich and Michelin are both available. The RSX’s 215/45R17 and the TSX’s 215/50R17 are covered by BFGoodrich, while the RSX’s 225/45R17 and the TL’s 235/45R17 have BFGoodrich and Nitto options.
That brand spread gives Acura owners a useful mix of choices depending on size. Some fitments have a broader selection within one brand family, while others let you choose between different brands in the same size. The key is to compare within the correct fitment first rather than trying to pick a brand across the entire year and make. Once the size is settled, then it makes sense to compare speed rating, load rating, rim-width suitability, and the intended character of each tire series.
What is the difference between BFGoodrich and Nitto choices for the 2006 Acura 225/45R17 and 235/45R17 sizes?
For 2006 Acura applications using 225/45R17 or 235/45R17, BFGoodrich and Nitto overlap in size but differ in exact product details. In 225/45R17, BFGoodrich options span rim-width ranges from 7.0 to 8.5 inches and 8.5 to 10.0 inches depending on series, while the Nitto NT555 G2 fits 7.0 to 8.5 inches and carries a 1,477-pound load rating at 50 psi. In 235/45R17, BFGoodrich products fit 7.5 to 9.0 inches, while the Nitto NT555 G2 also fits 7.5 to 9.0 inches and carries a 1,609-pound load rating at 50 psi.
The real implication is that series-to-series comparison matters as much as brand name. On a 2006 Acura RSX or TL, wheel width can narrow the field before tread design or brand preference ever comes into play, especially in 225/45R17 where one BFGoodrich option targets a much wider wheel range than the others. If you are deciding between BFGoodrich and Nitto, confirm your wheel width first, then compare load and sizing details within that narrower group instead of treating all same-size tires as interchangeable.
Fitting & Setup
What rim width do 2006 Acura tires require?
Rim-width recommendations vary by 2006 Acura size. 205/55R16 works on 5.5 to 7.5-inch rims, 215/45R17 works on 7.0 to 8.0-inch rims, 225/45R17 spans 7.0 to 10.0 inches depending on the product, 235/45R17 fits 7.5 to 9.0-inch rims, and 215/50R17 fits 6.0 to 7.5-inch rims. Those ranges are tied to the tire size and the specific tire series, not just to the Acura model badge.
That matters because two tires with the same nominal size can still prefer different wheel widths. A 2006 Acura RSX owner looking at 225/45R17 tires, for example, should confirm the actual wheel width before choosing among series because some products in that size are intended for substantially wider rims than others. Matching the tire to the wheel properly helps preserve intended tread shape, steering response, and bead seating, so it is worth checking the wheel before finalizing any tire choice.
Do 2006 Acura tires require inner tubes?
2006 Acura tires in the supported metric radial sizes are generally modern tubeless-type fitments, and a tubeless marking appears on at least one 205/55R16 product. Tube requirements can still vary by product marking and by the condition or design of the wheel itself, so it is better to confirm the exact tire and wheel combination than assume every same-size tire is marked identically. No tube-type collector construction appears in these Acura fitments.
For most stock Acura wheels from this era, owners will be working with tubeless radial tires rather than an inner-tube setup. The important check is making sure the wheel is clean, undamaged, and appropriate for tubeless service, especially on a car that has sat for long periods or has aftermarket wheels. If a particular tire has a tubeless marking, follow that product’s service guidance, and if the wheel condition is questionable, have it inspected before mounting rather than trying to solve a wheel problem with a tube.
Maintenance, Storage & Longevity
How should I store a 2006 Acura when the tires are fitted?
A 2006 Acura should be stored in a cool, dry, dark place with the tires kept away from direct sunlight, electric motors, welders, battery chargers, and other ozone-producing equipment. Keep the tires properly inflated during storage and move the car periodically so it does not rest on one contact patch for too long. Radial tires usually tolerate storage better than old bias-ply designs, but they still age from time, heat, and environment even when mileage stays low.
That means storage habits matter just as much as tread depth on an RL, RSX, TL, or TSX. If the car will sit for a season, clean the tires, maintain pressure, and consider using flat-stopper cradles or taking weight off the tires if the storage period is extended. A modern Acura may feel newer than a true antique, but its tires still need collector-car care if the car is driven only occasionally. Good storage practice can help reduce flat spotting, sidewall weathering, and premature replacement.
How long do tires on a 2006 Acura typically last?
On a 2006 Acura, tire age usually matters more than raw mileage because many surviving examples are driven intermittently. A sound rule is to begin evaluating the tires closely once they reach about five to seven years from the DOT date code, and to treat around ten years as the point where replacement deserves very serious consideration regardless of tread depth. Heat cycles, storage conditions, and inflation history can shorten that timeline.
That is especially relevant for cars like the RL or TSX that may look well preserved and still carry older rubber that appears acceptable at first glance. Tread depth alone does not tell the whole story on a low-use modern collector car. Check the sidewalls, the shoulder areas, and the date code on every tire, including the spare if it is still serviceable. If the tires are aging out, replacing them before regular road use is wiser than trying to extract one more season from old rubber.
How often should tires on a 2006 Acura be inspected?
Tires on a 2006 Acura should be checked before every drive, with a more thorough inspection before any long trip or highway run. Look for cracking, punctures, bulges, uneven wear, and pressure loss, and make sure the tread is wearing evenly across the width. Valve stems deserve attention too, because old stems can harden and leak even when the tire itself still looks usable.
That routine is important on a car that may alternate between long storage periods and spirited use. An RSX or TL that sees occasional weekend driving can go from seemingly fine to clearly overdue for service if the owner is not watching sidewall condition and pressure retention. A quick inspection before each drive only takes a minute and can catch the kind of age-related issues that are common on 2006-era cars, especially if the tires have not been replaced in several years.
Restoration & Authenticity
What tires were originally fitted to the 2006 Acura RL?
A 2006 Acura RL was originally a radial-tire car, and the key authenticity point is using the correct size and wheel system rather than trying to replicate an earlier-era construction. The RL fitments here are 245/50R17 and 245-680R460, both radial sizes, with the second tied to a metric-millimeter wheel. Acura from this period was built around modern high-performance radial behavior, not bias-ply tradition or vintage sidewall treatments.
For authenticity, the first job is verifying which wheel setup your RL actually has. A correct-size radial on the correct wheel preserves the car’s intended stance and overall character much better than forcing a near-match that happens to be easier to find. If you are preparing a particularly original car for marque judging or a high-level presentation, confirm the factory wheel-and-tire combination through Acura literature or marque specialists, especially if the car may have been converted from the 460 millimeter system to conventional 17-inch wheels during its life.
Does correct tire fitment matter for showing a 2006 Acura?
Yes, correct tire fitment matters on a shown 2006 Acura because judges and knowledgeable enthusiasts notice whether the size, sidewall treatment, and overall stance suit the car. For a neo-classic performance-luxury Acura, the expected look is a modern blackwall radial in the proper size for the model and wheel package. An RL on the wrong wheel system or an RSX wearing the wrong-profile tire can stand out immediately, even before anyone studies details more closely.
The practical standard is different from concours judging on a prewar or muscle-era car, but accuracy still counts. You are less likely to be judged on vintage-style construction details and more likely to be judged on whether the car presents as a correct, coherent 2006 Acura. If show correctness matters, confirm the original wheel diameter, keep the profile close to the proper model fitment, and avoid cosmetic tire choices that look out of period for a mid-2000s Acura performance-luxury vehicle.
What is the difference between BFGoodrich g-Force Comp 2 A/S and BFGoodrich g-Force Sport Comp 2 for a 2006 Acura?
For a 2006 Acura, BFGoodrich g-Force Comp 2 A/S and g-Force Sport Comp 2 often overlap in the same sizes, but their exact spec details can differ. In 225/45R17, for example, the g-Force Comp 2 A/S fits 7.0 to 8.5-inch rims, while the g-Force Sport Comp 2 is built for 8.5 to 10.0-inch rims. In 205/55R16, 215/45R17, 235/45R17, and 215/50R17, both series appear again, usually with similar W speed ratings but with differences in load notation and intended wheel-width range.
For an owner focused on authenticity and presentation, both series still read as modern blackwall radial choices appropriate to the era, but wheel compatibility can separate them quickly. The smartest comparison is not simply all-season versus sport wording in the name; it is whether the tire’s approved rim width matches the wheel on your Acura. On a show-minded TL, TSX, or RSX, a properly fitted tire that sits correctly on the wheel will usually preserve the car’s appearance better than a technically same-size tire chosen without checking width requirements.
Safety & Road Use
Are 2006 Acura tires safe for highway driving?
Yes, 2006 Acura tires in these supported radial sizes can be suitable for highway driving when they are the correct size, properly mounted, correctly inflated, and in sound age and condition. The available 205/55R16 products include W and Y speed ratings, with ceilings of 168 mph and 186 mph respectively, while the 215/45R17, 225/45R17, 235/45R17, and 215/50R17 products carry W ratings to 168 mph. Those ratings exceed normal U.S. highway speeds by a wide margin.
The bigger real-world limit on a 2006 Acura is usually not the tire’s top speed rating but the total condition of the car and the age of the tire itself. Brakes, suspension bushings, alignment, and old rubber all matter more to day-to-day safety than headline speed capability. If the size is correct and the tire is fresh enough to trust, modern radial construction is entirely appropriate for regular road use. If the tire is aging, cracked, or losing pressure, even an impressive speed symbol does not make it a wise highway choice.
What inflation pressure should I use for 2006 Acura tires?
Inflation pressure on a 2006 Acura should start with the factory vehicle recommendation for the exact model, wheel, and tire size, then be cross-checked against the tire’s own maximum-load and maximum-pressure marking. Available product figures vary by size: 205/55R16 reaches 1,356 to 1,477 pounds at 50 to 51 psi depending on product, 215/45R17 reaches 1,201 to 1,356 pounds at 50 to 51 psi, 225/45R17 reaches 1,356 to 1,477 pounds at 50 to 51 psi, 235/45R17 reaches 1,477 to 1,609 pounds at 50 to 51 psi, and 215/50R17 reaches 1,521 pounds at 50 psi.
Those figures are load-and-pressure limits for the tire itself, not a blanket recommendation to inflate every 2006 Acura tire to the maximum on the sidewall. The correct operating pressure for an RL, RSX, TL, or TSX depends on the car, the axle loading, and the tire size installed. Use the door-jamb or owner’s-manual recommendation as your baseline, verify cold pressure regularly, and avoid transferring a pressure figure from one Acura model or size to another just because the tires look similar.
What should I check before taking a 2006 Acura on a longer drive?
Before a longer drive in a 2006 Acura, inspect each tire for cracking, cuts, punctures, bulges, uneven wear, and proper cold inflation pressure. Confirm that the size on the car matches the wheel package, especially on an RSX with multiple wheel options or an RL that may use either 17-inch or 460 millimeter wheels. Check the valve stems, and inspect the spare as well if the trip will take you far from home.
Tires are only one part of the pre-drive routine, but they are an easy place to catch trouble early. On a mid-2000s Acura that may have spent time in storage, old rubber, low pressure, or a mismatch between wheel and tire can undermine an otherwise healthy car. Once the tires pass inspection, it is smart to give the rest of the car the same attention: brakes, fluids, battery condition, and suspension. A few minutes in the garage can prevent a roadside problem that would have been simple to spot beforehand.
