Key Tools for Lexus Owners
Important Tips for Lexus Owners:

- Check Your Placard: Always refer to your Lexus's doorjamb sticker or owner's manual for OEM tire specifications and recommended pressures.
- F SPORT Models: For F SPORT models, ensure replacement tires meet the required speed and load ratings to maintain performance and safety. Staggered setups are common; use our Diameter Check tool.

OD = overall tire diameter. Always verify with your vehicle's door jamb placard — trim and region can vary.
ES 350 — Plus-one sizing
Upgrade from the base 215/55R17 to 235/45R18 on 18" wheels. Overall diameter stays at 26.3" — zero speedometer impact — while the wider, lower-profile tire noticeably sharpens steering response. A common and reversible upgrade.
RX 350/450h (2016–2022) — Comfort-focused swap
The stock 235/55R18 (27.7" OD) can be swapped to a 245/50R18 (28.0" OD, +0.3") for a slightly taller sidewall with more cushioning on rough roads. Speedometer reads ~1% fast — negligible. Choose a quiet touring compound for the quietest ride.
IS F Sport — Performance summer tires
The F Sport runs 225/40R18 stock. Staying on 18" rims, a 235/40R18 (25.4" OD, ~+0.3") gives a wider contact patch for improved cornering grip. Michelin Pilot Sport 4S and Continental ExtremeContact Sport 02 are popular choices for the IS platform.
