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): 235/60R19 (RX 350, RX 350h base), 235/50R21 (F Sport trims, RX 500h).
4th gen RX (2016-2022): 235/65R18 (RX 350, 350L, 450h, 450hL base), 235/55R20 (F Sport trims and optional across other trims).
The 235/65R18 (4th gen) and 235/60R19 (5th gen) 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.
Cross-shopping against a Volvo XC60? It's built on the same NVH-and-safety brief as the RX — see our Best tires for Volvo XC60 picks for the Volvo's wet-braking-first spec.

Frequently asked
How much do Lexus RX tires cost?
235/65R18: $125–175 per tire. 235/55R20 or 235/50R21: $145–210 per tire. A set of four installed (235/65R18): $500–700.
Does the Lexus RX 450h (hybrid) need specific tires?
The same size range applies. For the hybrid variants, low rolling resistance tires (Continental CrossContact LX25, Bridgestone Ecopia HL) help preserve the hybrid fuel economy advantage. The Michelin CrossClimate2 is the best balance between economy and all-weather capability.
How long should tires last on a Lexus RX?
A quality touring all-season on an RX typically goes a long way if you rotate on schedule and keep the pressure right. Heavier trims and lots of highway miles wear faster, and a car that bakes in the Georgia sun ages rubber regardless of tread. Have a shop check depth once a year so you're not caught off guard.
Are quieter tires worth it on a Lexus RX?
For an RX, usually yes. The cabin is built to be hushed, so a noisy budget tire stands out more than it would in a rougher vehicle. A comfort-focused touring tire keeps the ride serene and holds up well. If you drive a hybrid RX, a low-rolling-resistance option also helps protect your fuel economy.
