Tire Temperature Rating Explainer | Grades A, B, C
Understand UTQG tire temperature grades (A, B, or C) and what they mean for a tire's ability to resist and dissipate heat, affecting safety and performance.
A tire's Temperature grade (A, B, or C), part of the UTQG system, indicates its resistance to heat generation and its ability to dissipate heat effectively. Sustained high temperatures can degrade tire material and lead to failure, impacting safety and tire life. Grade A signifies the best heat resistance, crucial for high-speed driving or heavy loads, especially in hot climates. Grade C represents the minimum federal motor vehicle safety standard. This interactive tool helps you select a grade and understand its specific meaning.
- Locate the Temperature grade (A, B, or C) on your tire's sidewall. It is part of the UTQG ratings, usually found near 'TREADWEAR' and 'TRACTION'.
- Select this grade from the dropdown menu in the tool.
- The explanation for the selected grade will update automatically (or click 'Explain Grade' if a button is present).
- Review the general meaning and specific commentary for the chosen temperature grade.
