UTQG Tire Rating Guide & Score Chart

The tire grade system ensures that tires meet the safety standards required by the Department of Transportation (DOT). Tire quality grade is specific for passenger tires except for winter, run-flat, or deep-tread LT tire models. The UTQG rating chart is provided in the table below:
