The Acura RLX (discontinued 2020) was the flagship Acura sedan: front-wheel drive in the base, Sport Hybrid AWD in the hybrid. It competed with the Lexus GS and Cadillac CT6. It remains common in the used luxury car market. Tire selection should favor highway quiet, long wear, and wet safety.

Frequently asked
What tire size does the Acura RLX use?
245/40R19 on 19-inch alloy wheels. Both the RLX and RLX Sport Hybrid use the same size.
How much do Acura RLX tires cost?
245/40R19: $155 to $250 per tire. A full set of four installed runs $620 to $1,000.
Should I check tire age on a used Acura RLX?
Yes. The RLX has been out of production since 2020, so a used example can be riding on older tires even with plenty of visible tread. Check the DOT date code on the sidewall (the last four digits are the week and year of manufacture); most manufacturers recommend replacement at 6 years from that date regardless of remaining tread depth.
Should I replace all four tires on an RLX Sport Hybrid?
The Sport Hybrid uses all-wheel drive, so its four tires should match in model and tread depth to keep the system happy. On the front-drive base RLX it is less critical, and you can replace in axle pairs if two still have good tread. When they are all close, a matched set gives this quiet cruiser the balanced ride it is meant to have.
What kind of tire suits the RLX best?
This is a comfort-first luxury sedan, so a quiet touring all-season plays to its strengths, with long tread life, low road noise, and dependable wet grip. Sport Hybrid owners who want a little more edge can step up to a performance all-season without giving up much refinement. Match the size on your door-jamb sticker and keep all four the same.
