The 2007 Acura RL came from a period when Acura positioned its flagship sedan around refined performance, all-weather confidence, and a distinctly modern luxury character. For owners today, that means tire selection is less about broad guesswork and more about matching the exact configuration of the car. This model uses two radial fitments, 245/50R17 and 245-680R460, and the correct choice depends on the specific sub-model. That also makes sizing format important, because one fitment uses a familiar modern metric radial code while the other uses a millimetric radial format. Before choosing tires, confirm the exact trim and wheel setup on the car, especially if appearance or originality matters.
Which Tire Size Is Right for The 2007 Acura RL
The 2007 Acura RL uses two primary tire sizes, and the correct one depends on the exact sub-model. Both are radial fitments, but they use different sizing conventions, so the first step is confirming whether the car is an RL Base or an RL w/Technology Pkg. before comparing tire choices or planning any replacement.
245/50R17 is a modern metric radial size in which 245 identifies section width in millimeters, 50 is the aspect ratio, R indicates radial construction, and 17 is the rim diameter in inches. On the 2007 Acura RL, this size applies to the Base sub-model and reflects the straightforward modern sizing format most buyers recognize today. The practical advantage is easier interpretation when comparing tire dimensions and wheel compatibility. It is the right size to evaluate if the car is an RL Base and still uses its correct 17-inch wheel setup.
245-680R460 is a millimetric radial size, with 245 referring to section width in millimeters, 680 indicating approximate overall tire diameter in millimeters, R showing radial construction, and 460 referring to the wheel's millimetric diameter. On the 2007 Acura RL, this fitment belongs to the w/Technology Pkg. sub-model, so it should not be treated as interchangeable with the Base model's more familiar inch-based size. Its main significance is wheel matching, since millimetric tire formats require careful confirmation of the actual wheel and vehicle configuration before replacement.
Tire fitment on the 2007 Acura RL changes by sub-model, so identifying the exact version of the car matters before selecting a replacement. One sub-model uses a conventional 17-inch metric radial, while the other uses a millimetric radial format tied to a different wheel standard.

2007 Acura RL Base
The 2007 Acura RL Base uses the 245/50R17 radial size, giving it the more familiar modern metric fitment of the two RL configurations. Tire selection centers on confirming the 17-inch wheel setup and then choosing a replacement that preserves the intended size and overall road manners.
The 2007 Acura RL w/Technology Pkg. uses the 245-680R460 radial size, which is a millimetric fitment rather than a conventional inch-based modern metric size. That makes wheel confirmation especially important before replacement, since the correct tire must match the actual millimetric wheel setup on the car.
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
Common 2007 Acura RL tire questions usually come down to exact size, sub-model differences, wheel format, and what to inspect before putting the car back on the road. The answers below focus on fitment clarity first, then practical selection and maintenance concerns.
Tire Size & Fitment
What tire size fits a 2007 Acura RL?
A 2007 Acura RL uses either 245/50R17 or 245-680R460, depending on the sub-model. The RL Base uses 245/50R17, while the RL w/Technology Pkg. uses 245-680R460. Both are radial tire sizes, but they are not the same sizing system.
The important next step is confirming exactly which RL configuration is in front of you before ordering tires. A conventional 17-inch metric radial and a millimetric radial may appear similar in width and overall diameter, but the wheel standard is a critical difference that needs to be checked carefully.
What size rim does a 2007 Acura RL use?
The 2007 Acura RL Base uses a 17-inch rim with its 245/50R17 tire size. The RL w/Technology Pkg. uses a millimetric wheel format paired with 245-680R460, so it should not be treated as the same wheel standard simply because the tires have similar dimensions.
Wheel confirmation matters as much as tire size on this RL because the two fitments use different sizing conventions. Checking the existing wheel markings and verifying the exact sub-model helps prevent ordering a tire that matches the general proportions of the car but not the actual wheel it is mounted on.
Do all 2007 Acura RL sub-models use the same tire size?
No. The 2007 Acura RL Base uses 245/50R17, while the 2007 Acura RL w/Technology Pkg. uses 245-680R460. Both are radial tires, but the fitment changes with the sub-model, so there is not one universal primary tire size across every RL configuration.
That difference means trim identification is the first part of tire selection on this vehicle. It is also wise to confirm that the car still has its original wheel type, since a later wheel change or replacement set could alter what size is currently mounted and what should be compared next.
Choosing the Right Tire
What should I consider when choosing a 245/50R17 tire for a 2007 Acura RL?
A 245/50R17 tire for a 2007 Acura RL should first match the RL Base fitment and the car's 17-inch wheel setup. The size itself defines a modern metric radial with a 245-millimeter section width and a 50-series profile, so the priority is staying with the correct dimensions and construction.
Beyond the size code, compare the actual wheel on the car, the intended use, and the condition of the suspension and alignment. A luxury sedan like the RL responds best when tire choice supports the correct proportions and the wheel-tire package is matched carefully rather than chosen by width alone.
What should I consider when choosing a 245-680R460 tire for a 2007 Acura RL?
A 245-680R460 tire belongs on the 2007 Acura RL w/Technology Pkg. and should be selected with close attention to its millimetric wheel format. The size indicates a radial tire with 245 millimeters of section width and an overall diameter around 680 millimeters, paired to a 460-millimeter wheel standard.
The key buying decision is confirming that the car still carries the proper millimetric wheels before comparing any replacement. Millimetric fitments require more caution than a familiar inch-based size, so wheel markings, current tire size, and the car's actual setup should all be checked before moving forward.
How do I choose between the available tire sizes for a 2007 Acura RL?
Choosing between the two tire sizes for a 2007 Acura RL is not a matter of preference; it is a matter of matching the correct sub-model and wheel type. The RL Base uses 245/50R17, while the RL w/Technology Pkg. uses 245-680R460, and each belongs to a different fitment standard.
The simplest approach is to identify the trim, read the size on the current tires, and inspect the wheel itself before purchasing replacements. Similar section width does not make the two sizes interchangeable, especially when one uses a conventional inch-based rim and the other uses a millimetric format.
Restoration & Appearance
Does correct tire fitment matter for a 2007 Acura RL restoration?
Yes. Correct tire fitment matters on a 2007 Acura RL because the car used two distinct radial sizing systems depending on sub-model. Keeping the proper size and wheel relationship helps preserve the intended stance, wheel presentation, and overall character of the car rather than forcing a near-match that changes how it sits.
Appearance-minded owners should start by confirming whether the car is a Base model or a w/Technology Pkg. car and whether its current wheels match that configuration. When originality is especially important, compare the present setup with vehicle-specific historical references so the replacement tire supports the right visual result.
How does tire construction affect the appearance of a restored 2007 Acura RL?
On a restored 2007 Acura RL, construction is less of a styling debate than it would be on an older collector car because both primary fitments are radial. The visual effect comes more from using the correct size and wheel standard than from choosing between bias-ply and radial construction.
That makes proportion and wheel relationship the real appearance issues to watch. A tire that follows the proper RL fitment will usually preserve the sedan's intended stance better than a substitute chosen only because the numbers look close, especially on the millimetric Technology Package setup.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2007 Acura RL?
Yes. Modifications can affect tire fitment on a 2007 Acura RL, especially if the car has aftermarket wheels, suspension changes, or a conversion away from its original wheel format. Those changes can alter clearance, wheel width, and the relationship between the tire and the body or steering components.
A careful inspection is worthwhile before replacing tires on any modified RL. Checking wheel diameter, wheel type, current tire markings, and visible clearance at full steering lock helps prevent confusion between the Base model's 245/50R17 setup and the Technology Package's 245-680R460 configuration.
What should I inspect before driving a 2007 Acura RL on new tires?
Before driving a 2007 Acura RL on new tires, inspect wheel condition, lug hardware, tire pressure, and the basic condition of suspension and steering components. It also helps to confirm that the new tires match the correct fitment for the sub-model so the car is not being driven on the wrong wheel-and-tire combination.
A short visual check after installation can prevent larger problems later. Look for even seating on the wheel, adequate clearance around the fenders and suspension, and any signs of rubbing during low-speed turning. Rechecking pressure after the first drives is also sensible on a car that may have sat unused.
How often should tires on a 2007 Acura RL be inspected?
Tires on a 2007 Acura RL should be inspected regularly, not just when tread looks worn. Collector and low-use vehicles can develop age-related issues such as cracking, flat spotting, air loss, or sidewall damage even when they are driven infrequently, so visual checks remain important between longer trips.
A good routine is to inspect the tires before seasonal use, before a longer drive, and anytime the car has been stored for an extended period. Looking at tread wear, sidewalls, inflation, and general wheel condition helps catch problems early and confirms that the RL is still sitting on the proper fitment.
