The Holeshot HDs have a hell of a tread extending into the sidewall for awesome bite in ruts and are VERY flat (not rounded like most other tires) for maximum give resistance in cornering and max tread to trail traction. I run about 2.5 - 3 PSI max and they are hard as a rock.
"TAKING TRAIL TRACTION TO A WHOLE NEW LEVEL
High-performance trail riders and cross-country racers will be thrilled with the introduction of the all-new ITP Holeshot H-D, a tire like no other. This is the roughest, toughest, most aggressive Holeshot ever, engineered to handle the most extreme conditions possible.
The Holeshot H-D is wider than other trail riding and racing tires, which helps it to climb out and stay out of ruts. Assisting in this ability is a new, stepped shoulder knob design that provides an additional degree of side bite and rut control. Overall traction and mud clean-out has been enhanced with larger, wider-spaced lugs.
This tire¹s durability has been increased as well, with a special focus on the sidewall that¹s resulted in unmatched puncture resistance. And despite the rugged nature of the Holeshot H-D, it remains surprisingly light. "
