The IROK ND has the same performance characteristics as the famous IROK with one difference. The IROK is a directional tread design and the IROK ND has a non-directional tread. The IROK ND has the same traction in forward and reverse that is popular in the smaller sized tires. The IROK ND uses the same famous Three Stage Lug design, scooped lugs, blade and molded siping, tighter lug pattern and sidewall traction features combined to give a smooth comfortable ride.
This tire probably doesn't fit most of the current trend's 18" lift and 31" tire, maybe someone can make use.
