What size tires are on a Lexus LS 430?

In most LS 430 models, you’ll find two common tire-size configurations depending on the year and wheel package: 17-inch wheels with 235/55R17 tires, and 18-inch wheels with 245/45R18 tires. Always confirm the exact size for your specific vehicle by checking the door jamb placard or the owner’s manual.


Tire sizes by wheel option


Common configurations you may encounter


The LS 430 was offered with different wheel sizes across its production run, which means tire sizes varied accordingly. Here are the two most frequently seen setups in the US market:



  • 17-inch wheels: 235/55R17 tires

  • 18-inch wheels: 245/45R18 tires


These sizes cover the majority of LS 430 models, but regional variations and optional packages could lead to different specifications. Always verify the exact size on the vehicle you’re inspecting.


How to confirm your LS 430’s exact tire size


To make sure you’re using the correct size for replacements or rotations, follow these steps to verify the tire size on your specific car:



  1. Locate the tire size on the sidewall of each tire; it will appear as a sequence like 235/55R17 or 245/45R18.

  2. Check the door jamb placard on the driver’s side; it lists the recommended tire sizes for front and rear wheels, as well as the inflations.

  3. Consult the owner’s manual or a Lexus dealership if you’re unsure which size corresponds to your trim and year.

  4. If changes have been made (aftermarket wheels or tires), verify the VIN-specific recommended sizes with a dealer or technician.


Using the correct size is important for proper handling, speedometer accuracy, and overall ride quality.


Regional and model-year variations


Beyond the two common configurations, some markets outside the United States and certain model years offered alternative wheels or packages that could shift tire sizing. If you drive an LS 430 purchased abroad, or if your car has undergone wheel upgrades, the tire size may differ from the two sizes listed above. Always rely on the placard and official documentation for your exact vehicle.


Summary: The Lexsus LS 430 predominantly used two primary tire sizes—235/55R17 on 17-inch wheels and 245/45R18 on 18-inch wheels—though variations can occur by year and market. The safest approach is to check the door jamb placard or owner’s manual to confirm the precise size for your car.
