• Continuous Shoulder Rib Design: Provides superior resistance to irregular wear patterns common with commercial use, resulting in longer life and a quieter, more comfortable ride
• Wide Circumferential Grooves: Four deep grooves effectively channel water and slush away from the tire footprint to resist hydroplaning and enhance wet weather safety
