What does the letter grade 'A' in traction grading signify?

The letter grade 'A' in traction grading indicates that the tire achieves above 0.54 g of force on a wet asphalt surface during testing. This grade is part of the Uniform Tire Quality Grading (UTQG) system, which provides consumers with information about a tire's performance characteristics in various conditions, including traction on wet surfaces. A grade of 'A' suggests that the tire has superior wet traction capabilities, enhancing the overall safety and performance of the vehicle when driving in rainy or wet conditions. This grading helps consumers make informed decisions about tire purchases based on their driving needs and environmental conditions.
