What type of tire rating indicates the most heat resistance?

The tire rating system categorizes tires based on their heat resistance and overall performance under different load conditions. A tire rated 'A' indicates the highest level of heat resistance among the options provided. This is crucial for maintaining vehicle safety and performance, particularly under high-stress driving scenarios such as heavy loads or long-distance travel, as it helps prevent tire blowouts and enhances longevity.

While ratings 'B', 'C', and 'D' indicate progressively lower heat resistance, they may not withstand extreme conditions as effectively as those rated 'A'. Recognizing the significance of heat resistance is essential for safe driving, especially in situations where tires are subjected to increased friction and temperature buildup. Understanding these ratings helps drivers choose suitable tires for their specific driving needs and conditions.
