The MT/R like ANY other MT type of tire needs wheel spin to clean out.Goose the throttle and spin those suckers and the MT/R's clean out better then any BFG
Where I live, my experiance has been the opposite.
Even with wheelspin, which you need to clean out any tire, the MTR's just don't dig in and grab in mud as well as most other MT's.
I, personally, am going Bighorns, Cooper STT's, or Kumhos for my next set of MT's.
As far as recalls go...the ProCraps use the same carcass as any other Cooper-built tire in similar sizes (MT ATZ, Cooper ATR, American Prospector AT, Sigma Stampede AT/S) but Cooper, unlike some other manufacturers, is quicker to recall than many others.
Course, maybe that's just me stickin up for the Ohio boys, ya know?
