How to verify your exact rim size on your Lexus GX
To determine the precise rim size for your vehicle, use these steps. The information you need is usually shown on the tire placard or in official documentation.
- Find the tire and rim information on the door jamb placard; it lists the recommended rim diameter for the tires installed on that vehicle.
- Check the owner's manual or the vehicle’s information display for wheel size specifications.
- Consult the Lexus build sheet or VIN-specific specifications through Lexus’s official portal or a authorized dealer.
- If you’re shopping a used GX, review the listing for the wheel size or look for a photo of the wheels that shows the size marking.
With the exact rim size confirmed, you can compare aftermarket options or ensure replacement wheels match the original specifications for fitment and performance.
Summary
In short, the Lexus GX does not have a single universal rim size. Most current models use 18-inch rims as standard, with 20-inch rims available on higher trims or through factory options. To be sure of your vehicle’s exact size, check the door placard, the owner's manual, or Lexus official build data for your year and trim.
