The SuperMax HF1-Plus is a commercial tire that's designed for use on the steer axle of trucks and buses in on highway applications and features four wide grooves that force water out of the tread to reduce the risk of hydroplaning on wet roads. Closed shoulders fight off uneven wear to promote a longer tread life, and the HF1-Plus utilizes angled tread blocks to increase traction in dry, wet, and light winter weather conditions.
