Tire UTQG ratings show the treadwear grades, the temperature ratings, and the traction rating on tires.

Definition of UTQG. The UTQG intended to provide consumers with standardized tire durability, safety, and performance information. Since its implementation, the UTQG has undergone various modifications and refinements to improve the accuracy and relevance of the information it provides. As a response, regulations and testing methodologies have been periodically updated to enhance consistency and reliability. The primary purpose of the UTQG is to offer consumers a reliable and comparative measure of tire performance attributes critical to safety and efficiency.
