How to verify the exact tire size on your 2016 GS
To confirm your specific tire size, use these reliable checks on the car itself and in the documentation.
- Inspect the tire sidewalls for the size code printed on each tire (e.g., 235/45R18). This shows the actual installed size.
- Look at the driver’s door jamb placard, which lists the recommended tire sizes for the factory configuration.
- Consult the owner’s manual or a dealership if you need VIN-specific tire sizing information, especially if a wheel package is factory-installed or altered.
- If you’ve changed wheels or tires, compare the new size to the original spec sheet and ensure it complies with load and speed ratings for safe operation.
Keep in mind that aftermarket wheels or regional option packages can modify the stock size. When in doubt, rely on the door placard and the tire sidewalls for the correct specification.
Why tire size matters
Tire size influences handling, ride quality, rolling resistance, and accuracy of the speedometer. Using a size that’s too large or too small can impact traction, ABS performance, and fuel economy. If you’re considering new tires or wheels for a 2016 GS, ensure the selected dimensions match the vehicle’s intended load and speed ratings and, if necessary, consult a Lexus service professional.
Summary
For a 2016 Lexus GS, there isn’t a single universal tire size. The correct size depends on trim and wheel package, with common factory configurations including 235/45R17, 235/45R18, and a 19-inch staggered setup (front 235/40R19, rear 265/35R19) on F Sport variants. To be certain, check the tire sidewall, the door placard, and the owner's manual. If you’re replacing tires, prioritize sizes that match the original specifications and maintain proper load and speed ratings.
