The new Terra Trac HTS introduced by Hercules Tire & Rubber Co. features a closed inner shoulder design with low-angle shoulder grooves that reduce noise, maximize stability and resist irregular wear. A notched and siped solid center rib offers responsive steering and maneuverability in all-season conditions, notes Hercules. Four wide circumferential channel grooves maximize water evacuation to protect against hydroplaning. The Terra Trac is available in seven LT sizes, with wheel sizes ranging from 15 to 17 inches; 26 SKUs will be available in the first quarter.
