2017 Acura reflected the brand’s modern mix of luxury sedans, compact sport sedans, and high-performance engineering, from the approachable ILX to the flagship RLX and the exotic NSX. That spread matters because 2017 Acura did not use one common tire size across the lineup; seven radial sizes cover four distinct models, with each model carrying its own fitment pattern and, in the NSX’s case, a staggered front-and-rear setup. The real first step is identifying your exact model and then confirming whether you are matching original-size replacement needs, appearance goals, or the driving character you want from a modern radial performance tire.
Which Tire Size Is Right for Your 2017 Acura
Seven tire sizes are used across 2017 Acura vehicles, and they vary by model rather than being shared across the full range. Every size here is a radial, so the main decision is confirming the correct model and rim diameter first, then choosing the product style that matches how the car is driven and presented. Understanding that distinction before choosing a product saves time and helps ensure the right match.
Year(s): 2017|Fit(s): ILX|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. This ILX-specific size is available from BFGoodrich in Blackwall form, and the products in this size carry W speed ratings with a 112 mph ceiling. It suits an ILX owner who wants the original wheel diameter retained while choosing among contemporary radial performance-oriented options.
Year(s): 2017|Fit(s): ILX|Construction: Radial|Rim: 18 in
225/40R18 is a metric radial size that denotes a 225-millimeter section width, a 40-series aspect ratio, and an 18-inch wheel. This ILX-specific size is available from BFGoodrich and Nitto, all in Blackwall styling, with W speed ratings across the size for a 112 mph ceiling. It is the larger-diameter ILX fitment and makes the most sense when your car is already set up for 18-inch wheels and you want to stay with that factory-size direction.
Year(s): 2017|Fit(s): NSX|Construction: Radial|Rim: 19 in
245/35R19 is a metric radial size with a 245-millimeter section width, a 35-series aspect ratio, and a 19-inch rim diameter. This NSX-specific size is available from BFGoodrich and Nitto in Blackwall form, and the products carry W speed ratings with a 112 mph ceiling. It serves as the front fitment for the staggered NSX setup, so it should be matched to the correct rear size rather than treated as a universal 2017 Acura tire.
Year(s): 2017|Fit(s): NSX|Construction: Radial|Rim: 20 in
305/30R20 is a metric radial size that translates to a 305-millimeter section width, a 30-series aspect ratio, and a 20-inch wheel. This NSX-specific size is available from Nitto and Pro-Trac, with Blackwall, RWL, and Redline sidewall styles; speed rating wording varies by product, with the Nitto carrying a W rating for a 112 mph ceiling. It is the rear half of the NSX staggered arrangement, and the sidewall-style choices make it especially important to balance visual preference with the car’s intended use.
Year(s): 2017|Fit(s): RLX|Construction: Radial|Rim: 19 in
245/40R19 is a metric radial size with a 245-millimeter section width, a 40-series aspect ratio, and fitment for a 19-inch wheel. This RLX-specific size is available from BFGoodrich in Blackwall styling, and speed ratings vary by product between W at 112 mph and Y at 186-plus mph. It is the right choice for RLX owners who need the correct 19-inch size first and then want to compare product character within that same overall fitment.
Year(s): 2017|Fit(s): TLX|Construction: Radial|Rim: 17 in
225/55R17 is a metric radial size that uses a 225-millimeter section width, a 55-series aspect ratio, and a 17-inch wheel. This TLX-specific size is available from BFGoodrich in both Blackwall and Wide Whitewall styles, and the products in this size carry W speed ratings where marked, with a 112 mph ceiling. It gives TLX owners a choice between a contemporary performance look and a more stylized sidewall treatment while staying with the same base size.
Year(s): 2017|Fit(s): TLX|Construction: Radial|Rim: 18 in
225/50R18 is a metric radial size with a 225-millimeter section width, a 50-series aspect ratio, and an 18-inch rim diameter. This TLX-specific size is available from BFGoodrich in Blackwall form, with W speed ratings across the size for a 112 mph ceiling. It fits TLX models equipped for 18-inch wheels and is the straightforward choice when you want to preserve the car’s original-size wheel and tire relationship.
Four Acura models are covered for 2017, and tire size changes from one model line to the next rather than carrying across the whole make. In practical terms, that means year and make alone are not enough; you need to identify whether you have an ILX, NSX, RLX, or TLX before narrowing down size. Select a model below to see model-specific fitment history and the products that apply to it.
2017 Acura ILX
The 2017 Acura ILX was Acura’s compact luxury sport sedan, aimed at buyers who wanted a smaller footprint with a more responsive feel than the larger sedans in the lineup. ILX fitments mount on either 17-inch or 18-inch wheels depending on configuration, so wheel diameter is the key first check before choosing tires.
The 2017 Acura NSX marked the return of Acura’s halo performance car, combining supercar proportions with a modern, technology-heavy engineering approach. Its tires mount on 19-inch front and 20-inch rear wheels, so the NSX requires attention to front-to-rear size pairing rather than a single all-around fitment.
The 2017 Acura RLX served as Acura’s full-size flagship sedan, with a more comfort-oriented mission than the ILX while still carrying the brand’s upscale, driver-focused identity. RLX tires mount on 19-inch wheels in this fitment group, which keeps the model’s choice centered on product selection within one size rather than moving between diameters.
The 2017 Acura TLX bridged the gap between the compact ILX and larger RLX, offering a midsize luxury sport sedan package with broad everyday appeal. TLX fitments mount on either 17-inch or 18-inch wheels, so confirming the car’s wheel diameter is the practical first step before narrowing to a tire.
Twenty-four products are available across seven tire sizes for 2017 Acura vehicles. 215/45R17 has 3 BFGoodrich radial Blackwall choices; 225/40R18 has 4 options from BFGoodrich and Nitto in radial Blackwall form; 245/35R19 has 3 from BFGoodrich and Nitto; 305/30R20 has 3 from Nitto and Pro-Trac in Blackwall, RWL, and Redline styles; 245/40R19 has 3 BFGoodrich Blackwall radials; 225/55R17 has 4 BFGoodrich radials in Blackwall and Wide Whitewall; 225/50R18 has 3 BFGoodrich radial Blackwall options. Confirm your size first, since speed ratings can vary within some sizes.
These FAQs focus on how 2017 Acura tire fitment changes from ILX to NSX, RLX, and TLX, how the metric radial sizes decode, and what sidewall, speed-rating, and collector-care details matter before choosing a tire.
Size Basics & Fitment
What tire sizes fit 2017 Acura vehicles?
2017 Acura vehicles use seven sizes across four models. The ILX uses 215/45R17 or 225/40R18, the NSX uses a staggered 245/35R19 front and 305/30R20 rear combination, the RLX uses 245/40R19, and the TLX uses 225/55R17 or 225/50R18. Rim diameters span 17, 18, 19, and 20 inches depending on model, and rim-width guidance appears on several sizes: 215/45R17 at 7.0 to 8.0 inches, 225/40R18 at 7.5 to 9.0 inches, 245/35R19 at 8.0 to 9.5 inches where shown, 245/40R19 at 8.0 to 9.5 inches, 225/55R17 at 6.0 to 9.0 inches depending on product, and 225/50R18 at 6.0 to 8.0 inches.
The practical takeaway is that 2017 Acura fitment is strongly model-specific. An ILX or TLX may have two possible diameters depending on wheel package, while the NSX uses two different sizes at the same time because of its front-and-rear stagger. Before choosing a tire, confirm the exact model, check the wheel diameter already on the car, and compare the tire’s approved rim-width range to the actual wheel.
What does 215/45R17 mean on a 2017 Acura tire?
On a 2017 Acura, 215/45R17 is a metric radial size. The 215 is the nominal section width in millimeters, 45 is the aspect ratio, meaning the sidewall height is 45 percent of the section width, R identifies radial construction, and 17 is the wheel diameter in inches. In this fitment group, that size applies to the ILX and mounts on 17-inch wheels, with approved rim widths running from 7.0 to 8.0 inches.
That decoding matters because it tells you more than just overall size. A 17-inch wheel cannot take an 18-inch or 19-inch tire, and the sidewall profile changes the look and driving feel compared with the taller or shorter alternatives used elsewhere in the 2017 Acura range. If your ILX wears factory-size 17s, stay with the correct size code first and then compare product choices inside that size.
Do all 2017 Acura models use the same tire size?
No. 2017 Acura uses different tire sizes across the ILX, NSX, RLX, and TLX, and none of the seven sizes are shared across every model. The ILX uses either 215/45R17 or 225/40R18, the TLX uses either 225/55R17 or 225/50R18, the RLX uses 245/40R19, and the NSX uses a staggered 245/35R19 front with 305/30R20 rear.
That means year and make are only the starting point. If you order by 2017 Acura alone, you could easily land on a correct Acura size that is wrong for your model or wheel package. The safest approach is to verify the model name, check the size molded on the tire currently on the car, and confirm whether the car uses a square setup or a staggered one.
Buying the Right Tire
What sidewall styles are available for 2017 Acura tires?
Most 2017 Acura tire sizes are offered in Blackwall form, which fits the modern factory look of Acura’s 2017 lineup. Two exceptions add visual variety: 305/30R20 for the NSX is available in Blackwall, RWL, and Redline versions, and 225/55R17 for the TLX is available in both Blackwall and Wide Whitewall form. Those alternatives change the visual character far more than the fitment basics, since the underlying size remains the same.
For most owners, Blackwall will be the natural match to a late-model Acura. The RWL, Redline, and Wide Whitewall options make more sense when appearance is a deliberate customization choice rather than an originality decision. If presentation matters as much as size, confirm the exact sidewall marking before making a final selection so the tire’s look matches the car’s build style.
What brands make tires for 2017 Acura vehicles?
BFGoodrich covers most of the 2017 Acura range, including 215/45R17, 225/40R18, 245/35R19, 245/40R19, 225/55R17, and 225/50R18. Nitto appears in 225/40R18, 245/35R19, and 305/30R20, while Pro-Trac is available in 305/30R20. Brand choice is therefore broadest on the ILX 225/40R18, NSX front 245/35R19, and NSX rear 305/30R20 sizes.
That brand spread gives some models more room to prioritize a specific look or product family than others. An RLX owner is choosing among BFGoodrich offerings inside one size, while an NSX owner can compare BFGoodrich and Nitto at the front and Nitto or Pro-Trac at the rear. Start with the correct size for the car, then narrow by sidewall style, speed rating, and the overall character you want from the tire.
What is the difference between BFGoodrich g-Force Sport Comp-2 and BFGoodrich g-Force Phenom T/A for the 2017 Acura RLX?
For the 2017 Acura RLX in 245/40R19, both are radial Blackwall tires built for a 19-inch wheel, but their marked specifications differ. The g-Force Sport Comp-2 carries a 98W designation and a max load figure of 1,653 pounds at 50 psi, while the g-Force Phenom T/A carries a 98Y designation with the same 1,653-pound load at 50 psi. Approved rim width also aligns closely at 8.0 to 9.5 inches.
The practical difference is that both fit the same size envelope, while the Phenom T/A carries the higher Y speed symbol and the Sport Comp-2 carries a W. That does not mean the RLX should be driven at those limits; it simply helps separate the tires within the same fitment class. If you are comparing RLX products closely, sidewall appearance stays the same, so speed symbol and product family become the main distinctions.
Fitting & Setup
What rim width do 2017 Acura tires require?
Several 2017 Acura sizes have defined rim-width ranges. The ILX’s 215/45R17 fits 7.0 to 8.0-inch rims, and its 225/40R18 fits roughly 7.5 to 9.0-inch rims. The NSX front 245/35R19 fits 8.0 to 9.5-inch rims where that range is shown, the RLX’s 245/40R19 fits 8.0 to 9.5-inch rims, the TLX’s 225/55R17 runs from 6.0 to 9.0 inches depending on product, and the TLX’s 225/50R18 fits 6.0 to 8.0-inch rims.
Rim width matters because two tires with the same wheel diameter can still be wrong for the wheel if the width is outside the approved range. That is especially important when a car has aftermarket wheels or when you are moving between trims that used different diameters. Check the actual wheel width before finalizing a tire, particularly on sport-oriented fitments with lower aspect ratios.
Do 2017 Acura tires require inner tubes?
The 2017 Acura sizes here are modern radial fitments, and none of the tire markings indicate tube-type construction. The product size markings use standard radial sizing and performance designations without TT markings, so these fitments are treated as tubeless radial applications. That aligns with the wheel and tire practice expected on late-model Acura passenger cars and the NSX.
Even with tubeless tires, valve stems and wheel condition still matter. A leaking stem, bent rim, or corroded bead seat can create the same practical problem as a damaged tire. When replacing tires on a 2017 Acura, inspect the wheels and stems at the same time so the finished installation seals correctly and maintains pressure consistently.
Maintenance, Storage & Longevity
How should I store a 2017 Acura when the tires are fitted?
A stored 2017 Acura should be kept away from direct sunlight, standing moisture, and ozone sources such as electric motors, battery chargers, welders, or air compressors. Clean, dry indoor storage is best, and maintaining correct inflation helps the tire keep its shape while parked. Because every fitment here is radial, long static periods are generally easier on the tire than with older bias-ply construction, but flat-spotting can still occur if the car sits for extended stretches.
Move the car periodically if possible, or use stands when the storage period is especially long and preserving the tires matters. That is especially sensible for vehicles with lower-profile fitments such as the ILX and NSX, where changes in pressure or shape are easier to feel once the car is back on the road. A few preventive steps in storage are far easier than correcting age-related damage later.
How long do tires on a 2017 Acura typically last?
On a 2017 Acura, tire age usually matters more than mileage once the car becomes a low-use vehicle. A sound rule is to begin careful evaluation around five to seven years of service and to treat ten years as the point where replacement deserves serious consideration regardless of tread depth. The DOT date code on the sidewall is the reference point for age, not the vehicle model year.
That guideline is especially useful on cars like the NSX or an infrequently driven RLX or TLX, where tread may still look acceptable even as the rubber ages out. A tire can appear serviceable yet still harden, crack, or lose wet-weather confidence over time. If the car is a collector or occasional-use vehicle, build age checks into your regular maintenance routine instead of relying on tread wear alone.
How often should tires on a 2017 Acura be inspected?
Tires on a 2017 Acura should be inspected before every drive and again before any extended trip. Check for sidewall cracking, cuts, bulges, irregular wear, punctures, and pressure loss, and look closely at the inside sidewall if the wheel design allows a clear view. Because these are tubeless radial fitments, valve stems and bead sealing should also be part of the inspection routine.
Frequent inspection matters most on low-mileage cars because age and storage conditions can create problems long before tread is worn out. A quick walkaround catches issues that are easy to miss in a garage-kept vehicle, especially on staggered setups like the 2017 Acura NSX where front and rear tires are different sizes. Make pressure checks part of the same habit so the car starts every drive on the right footing.
Restoration & Authenticity
What tires were originally fitted to the 2017 Acura ILX?
A 2017 Acura ILX was originally a modern radial-tire car, not a bias-ply-era vehicle, and its fitments in this group are 215/45R17 or 225/40R18 depending on wheel package. That means maintaining originality centers on staying with the correct metric radial size and wheel diameter for the specific car rather than choosing between vintage construction types. Sidewall appearance would have been modern and understated rather than styled for a period restoration market.
For an owner who wants the car to remain true to how Acura built it, the key is matching the exact size already associated with the car’s wheel package. If there is any uncertainty because of a wheel change during the car’s life, check the placard, owner’s literature, or a marque specialist familiar with 2017 Acura applications. That approach preserves authenticity without guessing from appearance alone.
Does correct tire fitment matter for showing a 2017 Acura?
Yes, correct tire fitment still matters when showing a 2017 Acura, even though the car comes from a modern era rather than a traditional concours-bias-ply period. Judges and knowledgeable enthusiasts will notice if the car wears the wrong diameter, the wrong front-to-rear relationship on an NSX, or a sidewall style that clashes with the car’s original character. On a late-model Acura, accuracy usually means proper size, proper stance, and an appearance that matches the car’s production-era intent.
That matters most when a car is being presented as a preserved or carefully restored example rather than as a customized build. A TLX with a Wide Whitewall or an NSX with a decorative sidewall treatment creates a different statement than a stock-appearing modern performance presentation. If the event has formal judging standards, verify them ahead of time so the tire choice supports the class you intend to enter.
What is the difference between BFGoodrich g-Force Comp 2 A/S and Nitto NT555 G2 for the 2017 Acura ILX?
For the 2017 Acura ILX in 225/40R18, both the BFGoodrich g-Force Comp 2 A/S and Nitto NT555 G2 are radial Blackwall tires carrying a 92W designation. Both fit 18-inch wheels, and their rim-width ranges overlap at 7.5 to 9.0 inches, with the Nitto showing 8.0 inches as the measuring width inside that range. The Nitto is slightly lighter at 23.89 pounds, while the BFGoodrich g-Force Comp 2 A/S is 25 pounds.
Because the size, speed symbol, and general fitment envelope are so close, the decision comes down to the product family you prefer and the details that matter to your build. On an ILX kept near factory appearance, either stays within the correct basic size and sidewall style. If you are comparing them closely, use wheel width, product character, and any brand preference as the deciding factors rather than trying to force a difference in size compatibility.
Safety & Road Use
Are 2017 Acura tires safe for highway driving?
Yes, the 2017 Acura sizes here are modern radial tires and are appropriate for highway use when they are in good condition, correctly inflated, and matched to the proper wheel. Most of these sizes carry W speed ratings, which correspond to a 112 mph ceiling, while one 245/40R19 option carries a Y rating with a 186-plus mph ceiling. Those symbols describe the tire’s rated capability, but on public roads the car’s condition, alignment, brakes, suspension, and legal speed limits matter more in normal use.
The more important distinction is not whether the tire can handle highway driving, but whether you have the correct size and a healthy, age-appropriate tire on the car. A fresh 17-inch TLX tire and a fresh staggered NSX set can both be highway-capable, but each must be used in its intended application. Before any sustained trip, check age, pressure, and visible condition rather than relying only on tread depth.
What inflation pressure should I use for 2017 Acura tires?
Inflation pressure for a 2017 Acura should start with the factory recommendation for the exact model and wheel package, then be checked against the tire manufacturer’s own rated pressure on the specific tire. Several products also state load-and-pressure relationships: 215/45R17 reaches 1,201 to 1,356 pounds around 50 to 51 psi depending on product, 225/40R18 reaches 1,235 to 1,389 pounds around 50 to 51 psi, 245/40R19 reaches 1,653 pounds at 50 psi, 225/55R17 reaches 1,609 to 1,819 pounds around 50 to 51 psi, and 225/50R18 reaches 1,709 pounds at 50 psi where marked.
Those figures are tire ratings, not a blanket instruction to run every 2017 Acura at those pressures. A rated maximum load pressure serves a different purpose than the carmaker’s recommended cold inflation for normal driving. Use the vehicle placard and owner’s manual as the first authority for everyday pressure, then confirm the tire’s own sidewall and manufacturer guidance so the chosen product is being used correctly.
What should I check before taking a 2017 Acura on a longer drive?
Before a longer drive in a 2017 Acura, inspect every tire for cracking, cuts, bulges, punctures, and uneven wear, then confirm cold inflation pressure and verify that each tire matches the correct size for the wheel position. On an NSX, that means making sure the 245/35R19 front and 305/30R20 rear tires are not mixed up; on ILX and TLX models, it means confirming whether the car is on the 17-inch or 18-inch package. The spare, if present, also deserves a pressure and condition check.
Tires are only one part of the pre-drive routine, but they are the part in direct contact with the road. A sound inspection should be paired with checks of brakes, fluids, and suspension condition, especially on a vehicle that has spent time parked. Spending a few minutes on those basics helps you catch age-related issues before they become roadside problems.
