What size tires are on the 2018 Acura TLX?

The 2018 Acura TLX typically uses 235/45R18 tires on 18-inch wheels, while the sportier A-Spec model upgrades to 235/40R19 tires on 19-inch wheels. Always verify the exact size listed on your vehicle’s door jamb placard, since wheel options can vary by trim and package.

In more detail, the TLX was offered in several trims with different wheel/tire configurations. For most standard configurations, 18-inch wheels with 235/45R18 tires are common. The A-Spec variant, designed for enhanced handling and a sportier feel, uses larger 19-inch wheels paired with 235/40R19 tires. If your TLX has aftermarket wheels or a non-standard package, the tire size may differ, so checking the placard or the owner’s manual is the best way to confirm.

Standard tire sizes by trim

Here is a quick reference to the typical tire sizes you’ll encounter on a 2018 TLX, depending on wheel setup. Note that optional packages or aftermarket wheels can alter these specifications.

• Base TLX, Tech, and Advance trims (18-inch wheels): 235/45R18


• A-Spec trim (19-inch wheels): 235/40R19

Always verify with the driver’s door jamb placard or the owner’s manual for your exact configuration.

Why tire size matters and how to verify

Tire size influences ride quality, handling, and speedometer accuracy. When replacing tires or upgrading wheels, it’s important to match the original size or consult Acura’s guidelines to maintain intended performance and safety characteristics.

Notes for replacement and upgrade

If you replace tires, ensure the load index and speed rating are appropriate, and consider diameter differences if you change wheel sizes. For the A-Spec’s 19-inch wheels, sticking with 235/40R19 helps preserve the intended balance of performance and comfort.

Summary

The 2018 TLX generally uses 235/45R18 tires on 18-inch wheels, with the A-Spec model using 235/40R19 on 19-inch wheels. Always confirm the exact size on your car’s door placard and consult the owner’s manual for any variations tied to options or regional specifications.
