Rocks, Hardpack tire...not a mudder
Great low rolling resistence, great side lugs, light weight as both a UST & tube tire and my old set has lasted for all 2 years of a drought here in Texas. Great tire if you're running it in dry conditions. Loved it in the limestone ledges and scree and loose dirt. For the clay + limestone in my area this is NOT a mud tire. It packs up pretty quickly. So it's not a wet season tire by far.
