The 2005 Acura RL arrived as a flagship sport-luxury sedan from an era when refined road manners, all-weather confidence, and understated design were central to the car’s appeal. Buyers looking at this generation often want to preserve that balanced character rather than over-tire the car or disrupt its ride quality. The 2005 Acura RL uses a 245/50R17 radial tire, giving this page a straightforward fitment foundation. The real choice is less about size and more about selecting the right tire within that size for road use, appearance, and wheel compatibility. That matters whether the goal is maintaining a stock-style setup or confirming fitment on a carefully kept driver.
Which Tire Size Is Right for The 2005 Acura RL
The 2005 Acura RL uses one primary tire size: 245/50R17, a radial fitment on a 17-inch rim. That same size applies to the RL Base, so the key decision is not choosing between multiple primary sizes, but selecting the right 245/50R17 tire for your wheel setup, intended use, and overall condition of the car.
A 245/50R17 size reads as a 245-millimeter section width, a 50-series aspect ratio, radial construction, and a 17-inch rim diameter. On a 2005 Acura RL, that modern metric radial format matches the car’s original-era design language and supports the kind of balanced ride, handling, and highway use expected from a premium sedan of this period. Because this is the standard fitment for the RL covered here, selection usually comes down to confirming the actual wheel size on the car and avoiding changes that upset clearance or overall proportions. It is the right starting point for a stock-size replacement.
Tire fitment is straightforward for the covered 2005 Acura RL sub-models. The shared tire size makes the decision more about choosing the right tire within that fitment and confirming the car still wears the correct 17-inch wheel setup.

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
Owners of a 2005 Acura RL usually need clear guidance on the 245/50R17 size, 17-inch rim fitment, stock-size replacement choices, and the checks worth making before driving on new or older tires.
Tire Size & Fitment
What tire size fits a 2005 Acura RL?
The 2005 Acura RL uses a 245/50R17 tire size. That is a radial fitment, and it is the primary size for the RL covered here, including the Base sub-model.
Using the correct size matters because the RL was designed around that combination of width, profile, and 17-inch rim diameter. If the car has aftermarket wheels or a previous owner changed sizes, check the actual wheel dimensions and the clearance around the suspension and fenders before assuming the current setup is the right one.
What size rim does a 2005 Acura RL use?
The 2005 Acura RL uses a 17-inch rim with its 245/50R17 tire size. In tire sizing terms, the final number in 245/50R17 identifies the wheel diameter the tire is built to mount on.
That 17-inch figure is the first thing to confirm before replacing tires, especially on a sedan that may have seen wheel changes over time. Matching tire size to rim diameter is essential, but wheel width and overall wheel design should also be checked so the replacement setup maintains proper seating, clearance, and road behavior.
Does the 2005 Acura RL Base use the same tire size?
Yes. The 2005 Acura RL Base uses the same 245/50R17 radial tire size as the covered 2005 Acura RL fitment. That keeps replacement sizing simple because there is no separate primary size to sort through for this sub-model.
Even with shared fitment, it still helps to inspect the car before choosing a replacement. A wheel swap, suspension change, or uneven wear pattern can affect what works well in practice, so confirm the wheels are still 17-inch units and check for any clearance issues before mounting new tires.
Choosing the Right Tire
What should I consider when choosing a 245/50R17 tire for a 2005 Acura RL?
Start with the correct size, which for the 2005 Acura RL is 245/50R17 on a 17-inch rim. Since this is a modern radial fitment, the main decision is choosing a tire that suits the car’s intended use while preserving the balanced ride and road manners expected from a luxury sedan.
Wheel condition, actual wheel dimensions, and the car’s current setup all deserve a look before purchase. A well-kept stock vehicle may only need a straightforward same-size replacement, while a car with altered wheels, alignment issues, or suspension wear should be checked carefully so the new tires are selected around the real setup rather than assumptions.
How do I choose between available 245/50R17 tires for a 2005 Acura RL?
The best comparison points are size accuracy, radial construction, and compatibility with the RL’s 17-inch wheel setup. Since the primary fitment is already narrow in scope, the decision usually comes down to choosing a replacement that maintains the car’s intended proportions and everyday drivability.
It helps to think about how the sedan is used now, not just how it looked when new. A lightly driven preserved car, a regular highway cruiser, and a vehicle with aftermarket wheel changes can each call for a different level of fitment scrutiny, so check wheel specs, inspect for rubbing history, and compare the condition of the suspension before finalizing a tire.
What rim-fitment factors should I compare when choosing 2005 Acura RL tires?
The first rim-fitment factor is wheel diameter, which needs to match the RL’s 17-inch requirement for 245/50R17 tires. After that, wheel width and the actual wheel design should be considered so the tire mounts properly and maintains the intended relationship to the car’s body and suspension.
Small differences in wheel setup can matter, especially if the Acura no longer has its original wheels. Looking at the full wheel and tire package helps avoid avoidable issues such as poor bead seating, steering interference, or fender contact, and it gives a clearer picture of whether a stock-size replacement is still the right path.
Restoration & Appearance
Which tire should I choose for a period-style 2005 Acura RL?
A period-style approach for a 2005 Acura RL starts with the correct 245/50R17 radial size. Keeping the stock-size format preserves the sedan’s original-era stance and avoids the oversized or under-profiled look that can change how a well-kept RL presents on the road.
Appearance matters, but so does the relationship between the tire and the wheel actually on the car. For a preservation-minded result, confirm the RL still wears the proper 17-inch wheel setup and avoid substitutions that alter the visual balance, steering response, or body clearance that give the car its intended character.
Does correct tire fitment matter for a 2005 Acura RL restoration?
Yes, correct tire fitment matters because the 2005 Acura RL was designed around a 245/50R17 radial on a 17-inch rim. Using the proper size helps maintain the car’s proportions and supports a more coherent restoration or preservation result.
Even on a modern collector-era sedan, tires influence both appearance and road behavior. A restoration-minded owner should verify the wheels currently on the car, inspect for past modifications, and keep records or marque-specific references handy if exact presentation matters, especially when trying to preserve an authentic early-2000s look.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2005 Acura RL?
Yes. Modifications such as aftermarket wheels, altered offsets, suspension changes, or lowering can affect tire fitment on a 2005 Acura RL even when the tire size remains 245/50R17. The size itself may be correct, but the full wheel-and-suspension package determines how much clearance the car actually has.
That is why a careful visual check is important before installing replacement tires. Look for signs of rubbing inside the fenders, near the struts, and during full steering lock, and confirm that the wheels still match the setup needed for a 17-inch radial fitment rather than relying only on the tire currently mounted.
What should I inspect before driving a 2005 Acura RL on new tires?
Before driving a 2005 Acura RL on new tires, inspect the wheels for damage, confirm the tire size is 245/50R17, and make sure the tires are seated properly on the 17-inch rims. It is also wise to check alignment condition, valve stems, and general suspension health.
A fresh set of tires cannot correct worn components or a poor wheel setup. Take a close look for uneven previous wear, loose steering feel, vibration, or signs that the car has been driven with incorrect pressure or alignment issues, since those problems can shorten tire life and affect how the RL behaves right away.
How often should tires on a 2005 Acura RL be inspected?
Tires on a 2005 Acura RL should be inspected regularly, not only by mileage but also by time and condition. A modern luxury sedan that is driven infrequently can still develop age-related issues such as cracking, flat spotting, pressure loss, or hidden damage long before the tread appears fully used.
Routine checks should include tread wear, sidewall condition, visible cuts or bulges, and stable air pressure across all four tires. Cars that spend long periods parked deserve extra attention, because storage conditions and underuse can age tires quietly, making inspection just as important as choosing the right 245/50R17 replacement.
