How to confirm the exact tire size for your GS350
To avoid guessing, use these steps to verify the correct tire size for your specific GS350:
- Inspect the door jamb placard on the driver’s side for the official tire size and recommended cold pressures.
- Examine the tire sidewall, which shows the size (for example, P235/45R18).
- Consult the owner’s manual for tire and load information and for recommended sizes for different trim levels.
- Check the vehicle identification number (VIN) or model year and trim with a Lexus dealer or official Lexus services website to confirm factory specs.
- If needed, ask a dealer or tire professional to confirm the correct size based on your VIN and market.
Verifying the exact size ensures proper fitment for tires, wheels, and performance, and avoids potential issues with speedometer accuracy and ABS/traction control calibrations.

Always confirm the exact size for your specific vehicle using the door placard, owner’s manual, or a Lexus dealer, especially if you’re shopping for replacements or winter tires. This ensures compatibility with suspension, wheels, and safety systems.
