The R-T1 from Radar is a commercial trailer tire designed specifically for long haul, regional and urban applications. Made from a low hysteresis tread compound, the tire gives excellent heat dissipation to reduce build-up and offer low rolling resistance. The tread pattern and depth are optimized to promote high mileage and fuel economy, and deliver a long and even wear life. The R-T1 features four wide grooves and sipes that channel water away from the contact area to reduce the risk of hydroplaning and improve wet weather performance.
