SM2.5

The Hoosier SM2.5 is a track and competition tire engineered for drivers demanding maximum grip and performance. Its extremely soft compound caters to autocross, time attack, and road racing enthusiasts seeking an edge in dry conditions. The SM2.5 is designed for experienced drivers who understand the trade-offs associated with ultra-high grip tires.

This tire prioritizes exceptional dry grip and responsive handling. The soft compound allows for maximum adhesion, translating to quicker lap times and enhanced cornering capabilities. Drivers can expect a significant improvement in braking performance and acceleration compared to typical street tires. The SM2.5's construction is focused on minimizing sidewall flex for precise steering response and predictable handling at the limit.

While specific construction details are proprietary, the SM2.5 utilizes advanced compound technology to optimize grip and heat management. The tread pattern is designed to maximize contact area, further enhancing dry traction. Due to its very soft compound, the SM2.5 exhibits reduced tread life and is not suitable for wet conditions or street use. It is intended for dedicated track vehicles or competition events where ultimate performance is the primary concern. The UTQG treadwear rating of 40 reflects its extremely soft compound and expected lifespan under racing conditions.
