2008 Acura RL Tires

A 2008 Acura RL uses one of two radial tire sizes: 245/50R17 or 245-680R460. The Base model uses 245/50R17, while the RL w/Technology/CMBS/PAX Pkgs. uses 245-680R460, so the correct tire size depends on the exact sub-model and wheel system on the car.

That distinction matters because these are different fitment systems, not just alternate labels for the same tire. Start by confirming the specific RL configuration and then inspect the wheels themselves, especially if the car has changed hands or has been updated over time. A car converted from the PAX setup may no longer use its original tire size.

The conventional 2008 Acura RL fitment uses a 17-inch rim with the 245/50R17 tire size. The 245-680R460 size belongs to a millimetric PAX-style arrangement, so it should not be treated as a standard 17-inch tire and wheel combination even though both belong to the same model year RL family.

Wheel confirmation is especially important on this car because the sub-model determines which system applies. Looking only at the tire size on paper is not enough if the vehicle has been converted or repaired in the past. Check the wheel markings, tire sidewall, and actual sub-model before choosing replacement tires or planning service.

The 2008 Acura RL has more than one tire size because different sub-models use different wheel and tire systems. The Base model uses a conventional 245/50R17 radial, while the RL w/Technology/CMBS/PAX Pkgs. uses the specialized 245-680R460 radial format tied to its PAX-related setup.

That means the first step is identifying the car correctly, not comparing tread patterns or brands. Once the exact configuration is confirmed, tire shopping becomes much more straightforward. Owners should also inspect the actual wheels on the car, since later conversions can change what size is needed even when the vehicle began life in a different configuration.

Choosing a 245/50R17 tire for a 2008 Acura RL starts with confirming that the car is the Base model or otherwise uses the conventional 17-inch wheel setup. After that, focus on selecting a tire that matches the vehicle’s intended road use, whether that means regular driving, seasonal use, or preserving a well-kept flagship sedan.

Wheel condition, suspension health, and alignment all affect how well a replacement tire performs on an RL. It also helps to inspect the current tires for uneven wear before replacing them, since unusual wear patterns can point to issues that a new tire alone will not solve. The goal is a correct fitment that supports the car’s balance and ride quality.

The choice between 2008 Acura RL tire fitments is determined by the car’s sub-model and wheel system, not by personal preference alone. A standard RL setup uses 245/50R17, while a Technology/CMBS/PAX-equipped car uses 245-680R460, so the correct fitment begins with identifying how the car is actually equipped today.

That is especially important on vehicles that may have been converted from one wheel arrangement to another. A tire that matches the original sub-model description may still be wrong if the wheels were changed later. Reading the tire sidewall, checking the wheel itself, and comparing that information to the car’s present setup will prevent costly fitment mistakes.

On a 2008 Acura RL, 245-680R460 is a millimetric radial size. The 245 refers to nominal section width in millimeters, 680 is the approximate overall tire diameter in millimeters, R identifies radial construction, and 460 refers to the millimetric wheel dimension used with the PAX-related arrangement.

For a buyer, the main takeaway is that this is a specialized fitment, not a standard modern inch-based size like 245/50R17. It points to a different wheel system, so replacement decisions should begin with careful wheel verification. That matters even more on older luxury sedans, where previous owners may have updated the original setup for convenience or serviceability.

Correct tire fitment matters on a 2008 Acura RL restoration because the car’s appearance and mechanical setup are closely tied to whether it uses the standard 245/50R17 arrangement or the 245-680R460 PAX-style system. Using the wrong fitment can change the car’s presentation and complicate wheel, service, and replacement decisions.

A restoration-oriented owner should decide early whether the goal is to preserve the original configuration or maintain a later wheel conversion already performed on the car. Either approach benefits from matching the tires to the actual wheel system in place. For authenticity-focused work, vehicle-specific reference material and marque expertise remain valuable before finalizing the setup.

Tire construction is less of an appearance divide on a 2008 Acura RL than it is on older collector cars, because both primary fitments for this model year are radial. The visual difference comes more from using the correct size and wheel system for the specific sub-model than from choosing between bias-ply and radial construction.

A restored RL looks most coherent when the tires match the car’s intended wheel arrangement, sidewall proportions, and overall stance. On a standard car, that means respecting the 245/50R17 setup, while a PAX-equipped car should be evaluated around its millimetric system. Getting those details right preserves the sedan’s clean, engineered appearance better than improvising size changes.

Yes, modifications can affect tire fitment on a 2008 Acura RL. Wheel changes, suspension alterations, lowering, brake upgrades, or conversions away from the original PAX-related setup can all change what tire size the car actually uses, even when the original sub-model would have pointed to a different factory-era fitment.

That is why the current wheel and tire setup should be inspected before ordering replacements. A car that now wears conventional wheels may need 245/50R17 even if it began life with 245-680R460, and the opposite assumption can create obvious problems. Clearance at full steering lock and under suspension compression should also be checked on modified cars.

Before driving a 2008 Acura RL on new tires, inspect tire pressure, wheel fastener torque, tread seating, valve stems, and the general condition of the wheels themselves. It also helps to look over the suspension and alignment condition, since worn components can affect how a fresh set of tires tracks and wears from the first miles.

A short, careful road test is useful after installation to confirm that the car drives smoothly and that there is no vibration, rubbing, or pull. Rechecking pressure after the first few drives is a sensible habit on any older vehicle. On an RL with an unusual wheel history, verify once more that the installed tires match the actual wheel system.

Tires on a 2008 Acura RL should be inspected regularly, especially if the car is driven infrequently or stored for long periods. Collector-minded and low-mileage sedans can develop aging-related issues even when tread depth still looks acceptable, so visual checks for cracking, bulges, punctures, and uneven wear are just as important as mileage-based monitoring.

Monthly pressure checks are a smart baseline, and a closer inspection before longer drives adds an extra margin of confidence. Attention should also be paid to air loss over time, since a slow leak may not be obvious at a glance. Vehicles that sit for extended periods benefit from clean, dry storage away from prolonged heat and direct sunlight.
