The 2011 Acura RL sits at the end of Acura’s flagship-sedan tradition, combining understated luxury with the kind of all-weather, technology-focused character that defined the model in its later years. For an owner, tire choice matters because this is a car that blends comfort, confident highway manners, and responsive road feel rather than leaning entirely toward either soft touring or sharp sport tuning. The 2011 Acura RL uses a 245/45R18 radial tire, so the real decision is choosing the right version of that size. Available options center on blackwall radial designs from BFGoodrich and Nitto across several performance-oriented series. The right pick depends on how the car is driven, the wheel setup on the car now, and the balance you want between period-appropriate luxury-sport character and modern road use.
Which Tire Size Is Right for The 2011 Acura RL
The 2011 Acura RL uses one primary tire size: 245/45R18, and it is a radial fitment for an 18-inch rim. The Acura RL Base uses this same size, so the main decision is not which factory size applies, but which 245/45R18 tire best matches the car’s current wheel setup, intended use, and preferred driving feel.
A 245/45R18 tire uses a 245-millimeter nominal section width, a 45-series aspect ratio, radial construction, and an 18-inch rim diameter. On the 2011 Acura RL, that sizing supports the car’s modern luxury-sport character and keeps the fitment centered on contemporary radial performance. Available choices in this size come from BFGoodrich and Nitto, with blackwall sidewalls and series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. Choosing within this size comes down to comparing rim-width compatibility, load details where stated, and the kind of road feel you want from the car.
Sub-model fitment is straightforward for the 2011 Acura RL. The covered RL Base model uses the same primary tire size, so selection is more about the tire itself than sorting through multiple fitment combinations.

2011 Acura RL Base
The 2011 Acura RL Base uses the 245/45R18 radial tire size on an 18-inch rim. That keeps tire selection focused on choosing among the available blackwall radial options and confirming that the wheel width and overall setup on the car still match the intended fitment.
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.

Owners of a 2011 Acura RL usually need clear answers on the correct 245/45R18 fitment, 18-inch wheel compatibility, differences between the available radial tires, and what to inspect before regular driving or a longer trip.
Tire Size & Fitment
What tire size fits a 2011 Acura RL?
The 2011 Acura RL uses a 245/45R18 tire size. This is a radial fitment, and it is the primary size used for the RL covered here, including the RL Base sub-model.
That means the first step is choosing a tire within the correct 245/45R18 size rather than sorting through multiple factory sizes. It is still worth checking the car’s current wheels before purchase, especially if it has aftermarket wheels or a previous owner changed the setup, because the right tire size still needs to match the actual wheel and vehicle configuration.
What size rim does a 2011 Acura RL use?
The 2011 Acura RL uses an 18-inch rim with its 245/45R18 tire size. The tire size itself confirms that the fitment is built around an 18-inch wheel diameter.
Wheel diameter is only one part of the fitment picture, so the next check is wheel width. The available 245/45R18 tire choices here call for rim widths in the 7.5- to 9-inch range, which makes it important to confirm the wheel on the car still falls within the intended specification before selecting a tire.
Does the 2011 Acura RL Base use the same tire size?
Yes. The 2011 Acura RL Base uses the same 245/45R18 radial tire size as the core 2011 Acura RL fitment shown here. There is no separate primary tire size to sort out for the Base model.
That simplifies the buying decision because fitment is consistent across the covered sub-model. Instead of comparing different size codes, the practical choice becomes comparing the available tires in that size by series, brand, load specification where stated, and rim-width compatibility, while also confirming the car has not been modified with a different wheel package.
Choosing the Right Tire
What should I consider when choosing a 245/45R18 tire for a 2011 Acura RL?
Start with the correct size, which is 245/45R18, and make sure the tire is built for an 18-inch wheel. From there, compare the available radial options by rim-width range, load details where stated, weight, and the overall character of the tire series.
The 2011 Acura RL is a modern flagship sedan, so the best choice depends on how the car is actually used. A car that sees regular highway driving may call for a different feel than one driven more aggressively, and any wheel change from stock-style dimensions should be checked carefully before settling on a specific tire.
What brands offer tires for the 2011 Acura RL?
The 2011 Acura RL has 245/45R18 tire options from BFGoodrich and Nitto. Within BFGoodrich, the available series include g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A, while Nitto is represented by the NT555 G2.
Brand alone should not be the only deciding factor. It helps to compare how each tire’s series, load specification where stated, and rim-width fitment align with the wheel and driving use of the car, especially if the RL is driven regularly and the owner wants the tire choice to suit both comfort and responsive road manners.
What tire series are available for the 2011 Acura RL?
The 2011 Acura RL has several 245/45R18 radial tire series available, including BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and the Nitto NT555 G2. All of them are blackwall tires built around the same basic fitment size.
Those series give the buyer useful comparison points within one correct size rather than forcing a size decision. Looking at series names alongside rim-width range, weight, and load details where stated can help narrow the field, particularly when the car’s wheel setup is known and the owner has a clear idea of how much emphasis to place on everyday use versus a more performance-oriented feel.
Restoration & Appearance
Which tire should I choose for a period-style 2011 Acura RL?
A period-style approach for a 2011 Acura RL starts with staying in the correct 245/45R18 size and keeping the car on an 18-inch radial fitment. Since the available options here are modern blackwall radials, the visual presentation remains in line with the understated look expected on a later Acura flagship sedan.
Appearance alone should not drive the choice. It makes sense to compare series character, wheel-width compatibility, and the way the car is actually used, especially because a well-kept RL often straddles the line between preservation and regular road use rather than strict concours-style restoration.
Does correct tire fitment matter for a 2011 Acura RL restoration?
Yes, correct tire fitment matters on a 2011 Acura RL restoration because the right 245/45R18 radial size helps preserve the car’s intended stance, wheel relationship, and overall visual balance. Even on a newer collector sedan, the tire still plays a major role in how finished the car looks.
A restoration-minded owner should also confirm that the wheel package on the car remains true to the setup being restored. If the RL has aftermarket wheels, altered suspension height, or a different offset than expected, the final appearance and fit can change noticeably even when the tire size itself appears correct.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2011 Acura RL?
Yes. A 2011 Acura RL may use the correct 245/45R18 tire size on paper and still run into fitment issues if the car has aftermarket wheels, altered offset, suspension changes, or body modifications. Tire fitment depends on the whole wheel-and-chassis package, not just the size code.
That is why it helps to verify the actual wheel diameter and width on the car before choosing among available tires. Clearance at the fender, inner suspension area, and steering range should also be checked, particularly on a car that has been lowered, repaired, or changed from its original wheel setup over time.
What should I inspect before driving a 2011 Acura RL on new tires?
Before driving a 2011 Acura RL on new tires, inspect wheel condition, valve stems, lug hardware, and inflation pressure, then make sure the tires are seated and balanced properly. It also helps to look over the suspension and alignment condition so the new tires are not immediately affected by an underlying chassis issue.
A short initial road test can reveal vibration, pulling, rubbing, or unusual noise that deserves attention before regular use. On a sedan like the RL, which is expected to deliver smooth highway manners, those checks matter because even the correct 245/45R18 size can feel wrong if the wheel, alignment, or suspension condition is off.
What should I check before a longer drive in a 2011 Acura RL?
Before a longer drive in a 2011 Acura RL, check tire pressure, tread condition, and the sidewalls for cuts, bulges, or cracking. The 245/45R18 tires should also be inspected for uneven wear, since that can point to alignment or suspension issues that become more noticeable on extended highway miles.
A longer trip is also a good time to confirm the spare strategy, wheel fastener condition, and that there is no rubbing at full steering lock or over suspension movement. Even a well-kept RL can have age-related issues if it sits for periods, so a careful pre-drive inspection is worthwhile before relying on the car for distance travel.
