Strengths: This 2.4 on an older santa cruz light with fox rlc fork. I use Stans system on K.B. valiant rims chris king hubs. Loose about 2 lbs of air between rides. I check air before each ride, noproblems in that dept. Rolls well for knobby and its good as advertised in loose rocks and sand and no problem climbing desending rocky slopes. I previously ran the conti vertical pro and this tire is a marked improvement. I ride only intermediate trails as a rule in phoenix area and this tire holds its own on southwest trails. I've had it on bike for 3 weeks, ride 4-5 days aweek. Seems to be wearing well with strong casing. I run it at 28 PSI on loose rocky trails.
