I get flex at 30 psi, 20 psi, 15 psi, and everywhere inbetween. 33" C load range.
I vote kevalrs. I was driving on gravel slopes this past weekend and never air'd down, perfect grip, no wheel spin to get up the steepest of climbs. I just walked right up what others had to spin their tires on. This is my second set of MTRs.
