2011 Acura RL Owner's Manual - Page 493

Tires It is best to replace all four tires at the same time. If that is not possible or necessary, replace the two front tires or two rear tires as a pair. Replacing just one tire can seriously affect your vehicle's handling. If you ever replace a wheel, make sure that the wheel's specifications match those of the original wheels. Also be sure you use only TPMS specific wheels. If you do not, the tire pressure monitoring system will not work on that tire. Replacement wheels are available at your dealer. Wheel and Tire Specifications Wheels: 18 x 8.0J AL (TPMS) Tires: P245/45R18 96V See page 528 for DOT tire quality grading information, and page 530 for tire size explanation. Installing improper tires on your vehicle can affect handling and stability. This can cause a crash in which you can be seriously hurt or killed. Always use the size and type of tires recommended in this owner's manual. Maintenance 487
