The 2010 Acura RL sits at the end of Acura’s flagship sedan era, blending understated luxury, all-weather confidence, and the kind of refined performance that still appeals to drivers who use their cars rather than simply store them. Tire choice on this car is more modern and straightforward than on many collector-era vehicles, with a single primary fitment: 245/45R18 radial. That keeps the focus on selecting the right 18-inch tire within the correct size, rather than sorting through multiple factory-style fitments. Available choices center on blackwall performance-oriented radials from BFGoodrich and Nitto, making wheel compatibility, driving use, and overall condition the key considerations before replacement.
Which Tire Size Is Right for The 2010 Acura RL
The 2010 Acura RL uses one primary tire size: 245/45R18, a radial fitment on an 18-inch rim. The RL Base uses this same size, so the main decision is not which size fits, but which tire best matches the car’s wheel setup, intended road use, and preference within the available radial choices.
In 245/45R18, the 245 identifies nominal section width in millimeters, 45 is the aspect ratio, R denotes radial construction, and 18 is the wheel diameter in inches. This is a modern metric radial size that suits the 2010 Acura RL’s late-model suspension, wheel, and handling character. Available choices in this size include blackwall tires from BFGoodrich and Nitto across series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. Selecting within this size comes down to verifying wheel width and choosing the product that best matches how the car will actually be driven.
Tire fitment is straightforward across the covered 2010 Acura RL lineup. The RL Base uses the same primary tire size, so selection is more about choosing the right radial tire within that fitment than sorting through different sub-model sizes.

Tire Size & Fitment
What tire size fits a 2010 Acura RL?
The 2010 Acura RL uses 245/45R18 as its primary tire size. This is a radial fitment built around an 18-inch wheel, and the covered RL Base sub-model uses that same size rather than a separate alternate fitment.
That means the key step is choosing the right tire within 245/45R18, not moving between multiple factory-style sizes. It is still smart to confirm the wheels currently on the car, especially if it has seen aftermarket wheel changes, and to compare rim-width suitability before mounting a replacement tire.
What size rim does a 2010 Acura RL use?
The 2010 Acura RL uses an 18-inch rim with its 245/45R18 tire size. The tire size itself confirms the wheel diameter, and the available tires in this fitment are built for 18-inch applications rather than smaller or larger wheel diameters.
Wheel diameter is only part of the picture, so the next check is wheel width. Available 245/45R18 products here are intended for rims in the 7.5- to 9-inch range, making it important to verify the actual wheel on the car before choosing among different radial options.
Does the 2010 Acura RL Base use the same tire size?
Yes. The 2010 Acura RL Base uses the same 245/45R18 radial tire size as the model core. There is no separate covered sub-model tire size to sort through, which keeps replacement selection more straightforward than on many multi-trim vehicles.
That shared fitment shifts the decision toward tire choice rather than fitment discovery. An RL Base owner should still check whether the car remains on its intended 18-inch wheels, since any wheel swap, offset change, or suspension modification can affect how a replacement tire works on the vehicle.
Choosing the Right Tire
What should I consider when choosing a 245/45R18 tire for a 2010 Acura RL?
Start with the correct size, 245/45R18, and make sure the tire is suited to the car’s 18-inch wheel. From there, compare radial product details such as rim-width range, load specification, tire series, and the kind of driving the RL will see most often.
This size includes several performance-oriented blackwall choices, so the decision is less about appearance variation and more about selecting the tire character that matches the car. A lightly used sedan, a daily driver, and a car that sees more spirited highway use may all point the buyer toward different priorities within the same size.
What brands offer tires for the 2010 Acura RL?
245/45R18 tires for the 2010 Acura RL are available from BFGoodrich and Nitto. Within those brands, the RL’s fitment includes several radial choices rather than a single product, giving owners some room to compare series and specification details.
Brand should be considered alongside the actual tire’s rim-width range, load figure, weight, and intended use. It is more useful to compare the complete specification of each 245/45R18 option than to choose only by brand name, especially on a sedan that balances comfort, handling, and real road use.
What tire series are available for the 2010 Acura RL?
The 2010 Acura RL’s 245/45R18 fitment includes BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Phenom T/A, and Nitto NT555 G2. All of them are blackwall radial tires sized for the RL’s 18-inch wheel fitment.
Those series names help separate the available choices within one size, but the smarter comparison still includes wheel-width compatibility and other product details. Looking at the full specification for each series will give a clearer picture than choosing by name alone, particularly if the car’s current wheels are not original.
Restoration & Appearance
Which tire should I choose for a period-style 2010 Acura RL?
A period-style approach on a 2010 Acura RL still begins with the correct modern fitment, 245/45R18. Because this is a late-model luxury performance sedan rather than a bias-ply-era vehicle, staying with the proper metric radial size preserves the car’s intended visual balance and wheel-to-tire proportion.
Appearance choice is more restrained here than on classic cars with whitewalls or redlines, since the available options are blackwall radials. For a stock-looking presentation, the best path is usually maintaining the correct size and checking that the car still wears the right wheel diameter and a tire profile that suits the original design.
Does correct tire fitment matter for a 2010 Acura RL restoration?
Yes. Correct tire fitment matters on a 2010 Acura RL restoration because the 245/45R18 size helps preserve the sedan’s stance, wheel-to-body proportion, and overall visual character. Even on newer collector-interest vehicles, the wrong aspect ratio or wheel diameter can change the car’s presentation noticeably.
Restoration-minded buyers should confirm what wheels are actually on the car before replacing tires. A stock-appearing RL benefits from keeping the proper size format and 18-inch fitment, while any search for exact delivery-day appearance is best supported by original vehicle literature, marque references, or other model-specific historical documentation.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2010 Acura RL?
Yes. Modifications can affect tire fitment on a 2010 Acura RL even when the replacement tire remains 245/45R18. Aftermarket wheels, altered offsets, suspension changes, or ride-height adjustments can all change clearance at the fender, inner wheelhouse, or steering components.
A car that looks stock can still have fitment changes underneath, so it is worth measuring the actual wheel and checking clearance before mounting new tires. That matters most when the RL has been lowered, fitted with non-original wheels, or driven with worn suspension parts that may change how the tire sits under load.
What should I inspect before driving a 2010 Acura RL on new tires?
Before driving a 2010 Acura RL on new tires, inspect the wheels for damage, confirm the tire size matches 245/45R18, and check that inflation is set appropriately for the installed tire. It is also smart to look over the valve stems, lug hardware, and general condition of the suspension and alignment-related components.
A short initial road test can reveal vibration, rubbing, or steering pull that should be corrected early. The RL is sensitive to wheel and tire condition, so proper balance, even wear, and a clean mounting surface all matter if the goal is a smooth highway-driving luxury sedan rather than a car that feels unsettled.
How often should tires on a 2010 Acura RL be inspected?
Tires on a 2010 Acura RL should be inspected regularly for pressure loss, uneven tread wear, cuts, bulges, and sidewall damage. On a car that is driven often, a quick visual check before longer trips and a more careful inspection at routine service intervals is a sensible habit.
Mileage is not the only concern, especially on an older luxury sedan that may spend time parked. Tires can age even when tread depth still looks serviceable, so occasional-use RLs deserve the same attention to cracking, flat-spotting, and air retention as daily drivers, particularly before sustained highway use.
