The 2006 Acura RL sits in the early-2000s luxury sport-sedan market, blending Acura refinement with the more advanced, technology-heavy character that defined the model in this era. It is a modern car by Coker standards, but one with a fitment story that still deserves close attention because two radial tire sizes apply across the RL lineup. The standard RL Base uses 245/50R17, while the RL with Technology Package uses 245-680R460, a millimetric radial format that looks familiar at a glance but should not be treated casually. The real key is matching the exact sub-model and wheel setup before comparing tire choices or planning road use.
Which Tire Size Is Right for The 2006 Acura RL
Two tire sizes apply to the 2006 Acura RL, and the correct choice depends on the exact sub-model. Both are radial tires, but they use different sizing systems, so the first step is confirming whether the car is an RL Base with 245/50R17 or an RL w/Technology Pkg. with 245-680R460 before moving on to any replacement decision.
245/50R17 is a modern metric radial size. The 245 identifies nominal section width in millimeters, 50 is the aspect ratio, R indicates radial construction, and 17 is the rim diameter in inches. On the 2006 Acura RL, this size applies to the Base model and represents the more familiar modern replacement format most buyers recognize quickly. It is the right place to start when the car still carries its original-style wheel setup, but wheel diameter and actual tire markings should still be checked before replacing a worn set.
245-680R460 is a millimetric radial size rather than a conventional inch-based modern metric size. The 245 reflects nominal section width in millimeters, 680 refers to the tire's overall diameter class, R indicates radial construction, and 460 denotes a metric wheel diameter rather than a 17-inch rim. On the 2006 Acura RL, this size belongs to the w/Technology Pkg. configuration, so the buyer's first concern is confirming the wheel and tire markings on the car itself. That step matters because millimetric fitment should never be assumed interchangeable with a similar-looking inch-based size.
Sub-model fitment matters on the 2006 Acura RL because the two covered configurations do not use the same tire size. Identifying whether the car is a Base model or an RL w/Technology Pkg. should come before any tire search, since the sizing systems are different.

2006 Acura RL Base
The 2006 Acura RL Base uses the 245/50R17 radial size, which is the more familiar modern metric format. That makes replacement selection more straightforward, but the wheel diameter and the exact sidewall markings should still be confirmed before mounting a new set.
The 2006 Acura RL w/Technology Pkg. uses the 245-680R460 radial size, which is a millimetric fitment rather than a standard 17-inch tire. Tire selection starts with verifying that metric wheel setup, since the size format itself is the main fitment issue on this sub-model.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.
Frequently Asked Questions
The most important 2006 Acura RL tire questions center on identifying the correct sub-model, understanding the difference between 245/50R17 and 245-680R460, and checking wheel compatibility, tire condition, and vehicle setup before the car goes back on the road.
Tire Size & Fitment
What tire size fits a 2006 Acura RL?
A 2006 Acura RL uses one of two radial tire sizes, depending on sub-model. The RL Base uses 245/50R17, while the RL w/Technology Pkg. uses 245-680R460. Those are not just two ways of writing the same size, so the exact configuration matters before any replacement is chosen.
The practical step is to read the tire sidewall currently on the car and confirm the wheel setup before ordering replacements. A Base model with 17-inch fitment should be approached differently from a Technology Package car with millimetric fitment, especially if the vehicle has had wheel changes at some point in its life.
What size rim does a 2006 Acura RL use?
The 2006 Acura RL Base uses a 17-inch rim with its 245/50R17 tire size. The RL w/Technology Pkg. uses a 245-680R460 tire, which is a millimetric radial format and should be treated as a metric wheel fitment rather than assumed to match a standard 17-inch wheel.
That distinction matters because tire mounting begins with the wheel, not just the section width on the sidewall. A buyer should verify the actual wheel diameter and the exact size marking on the current tire before selecting replacements, particularly on cars that may have received wheel swaps or other modifications over time.
Do all 2006 Acura RL sub-models use the same tire size?
No, the 2006 Acura RL sub-models covered here do not use the same tire size. The Base model uses 245/50R17, while the RL w/Technology Pkg. uses 245-680R460. Both are radial tires, but they belong to different sizing conventions and should not be grouped together casually.
That means the first fitment decision is identifying the exact sub-model and confirming the wheel actually on the car. Even when two tires appear close in section width, the wheel diameter standard and overall fitment method can differ, so replacement choices should always start with the sidewall and wheel markings.
Choosing the Right Tire
What should I consider when choosing a 245/50R17 tire for a 2006 Acura RL?
The main considerations are staying with the correct 245/50R17 size, confirming the car is the RL Base, and making sure the wheel is still a 17-inch setup. Because this is a conventional modern metric radial size, the size itself is straightforward once the sub-model and wheel have been verified.
From there, attention should shift to the actual condition and intended use of the car. A regularly driven RL may call for a different replacement approach than a lower-use example, and any aftermarket wheel, suspension, or alignment change should be checked so the new tires match the car's present setup rather than its original specification alone.
What should I consider when choosing a 245-680R460 tire for a 2006 Acura RL?
The first consideration is confirming that the car is a 2006 Acura RL w/Technology Pkg. and that it still uses the 245-680R460 millimetric radial fitment. This size is less familiar to many buyers than a standard inch-based metric tire, so careful attention to the sidewall marking is essential.
Wheel compatibility is the key issue here, because a millimetric tire must match the correct wheel standard. The safest approach is to inspect the current tire and wheel markings together, then check for any prior wheel conversion, brake work, or suspension alteration that could affect replacement planning or road clearance.
How do I choose between the available tire sizes for a 2006 Acura RL?
The choice is not based on preference between two optional sizes; it is based on the sub-model and wheel fitment the car actually has. A 2006 Acura RL Base uses 245/50R17, while an RL w/Technology Pkg. uses 245-680R460, so the correct size follows the hardware on the vehicle.
A useful routine is to confirm the trim, read the existing sidewall, and measure nothing by assumption. Once the installed wheel standard is confirmed, replacement becomes much simpler, and there is less risk of treating a millimetric fitment as though it were automatically compatible with a common inch-based tire.
Restoration & Appearance
Does correct tire fitment matter for a 2006 Acura RL restoration?
Yes, correct tire fitment still matters on a 2006 Acura RL restoration, especially because the RL Base and RL w/Technology Pkg. use different tire sizing systems. Keeping the proper size on the proper wheel helps preserve the car's intended stance, proportions, and overall presentation rather than introducing a visibly mismatched setup.
That is particularly important on cleaner, well-kept cars where wheel and tire details stand out more than many owners expect. A restoration-minded buyer should verify whether the car remains on its original wheel type or has been converted, then choose tires that suit the actual configuration rather than relying on appearance alone.
How does tire sizing affect the appearance of a restored 2006 Acura RL?
Tire sizing affects the visual balance of a restored 2006 Acura RL because the car was designed around a specific wheel-and-tire relationship for each covered sub-model. A Base model on 245/50R17 presents differently from a Technology Package car on 245-680R460, even when section width appears similar at first glance.
That is why appearance decisions should begin with the correct fitment, not just a close-looking substitute. Buyers concerned with preserving the car's intended profile should confirm the existing wheels, inspect ride height and clearance, and use marque-specific reference material if exact restoration presentation is part of the project.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2006 Acura RL?
Yes, modifications can affect tire fitment on a 2006 Acura RL even when the nominal tire size looks correct. Aftermarket wheels, suspension changes, altered ride height, brake conversions, or prior wheel swaps can all change the real-world space available for the tire and the wheel standard the car now uses.
That matters even more on an RL w/Technology Pkg. because millimetric fitment should be verified carefully. A buyer should confirm wheel diameter, wheel type, and present clearance at the fender and steering points before replacing tires, especially on a car with an unknown service history or enthusiast-owned modifications.
What should I inspect before driving a 2006 Acura RL on new tires?
Before driving a 2006 Acura RL on new tires, inspect the wheels for damage, confirm the correct size marking, and make sure the tires were mounted to the proper wheel standard. Tire pressure, valve stems, lug hardware, tread seating, and any visible clearance concerns should also be checked before regular road use begins.
A roadworthy setup also depends on the rest of the car. Alignment condition, worn suspension parts, brake drag, and uneven ride height can all affect how a new tire behaves, so an RL that has been stored, recently purchased, or infrequently driven deserves a careful once-over before any longer trip.
How often should tires on a 2006 Acura RL be inspected?
Tires on a 2006 Acura RL should be inspected regularly, with a closer look any time the car has been sitting for extended periods or before a longer drive. Pressure loss, sidewall cracking, cuts, bulges, irregular tread wear, and age-related hardening all deserve attention, even on tires that still look usable at a glance.
That inspection habit is especially important on a lower-mileage luxury sedan that may not be driven daily. Checking condition at intervals helps catch problems before they turn into vibration, poor tracking, or roadside trouble, and it also gives the owner another chance to confirm the car is still wearing the correct size and wheel setup.
