The Lexus RX is built to a higher NVH (noise, vibration, harshness) standard than most SUVs. Tire noise is one of the largest contributors to cabin noise in the RX — and the right tire makes a significant, noticeable difference.
Common Lexus RX tire sizes
5th gen RX (2023-current): 235/60R18 (RX 350 standard), 235/55R20 (RX 350 Premium, F Sport), 235/50R21 (F Sport S, RX 500h).
4th gen RX (2016-2022): 235/65R18 (RX 350, 350L), 235/55R19 (F Sport), 235/50R20 (RX 450hL).
The 235/65R18 and 235/60R18 cover the most common non-sport RX trims.
Best tires
Bridgestone Turanza QuietTrack in 235/65R18: the top recommendation for standard RX owners prioritizing cabin refinement. The Turanza QuietTrack is the quietest touring tire in its category — ideal for the RX's NVH-focused character.
Michelin CrossClimate2 in 235/65R18: for RX owners who want all-weather 3PMSF capability alongside long tread life.
Continental CrossContact LX25: excellent wet grip and fuel efficiency — the hybrid RX variants benefit from the lower rolling resistance.
Michelin Defender LTX M/S: for maximum tread life — the best per-mile cost option for high-mileage RX owners.
