Yep, the Pro-Comps are a little more and do not have the sidewall that the MTR's have. I have a friend that works for 4WP and he bought the MTR's.
Rick, RangerX, Paul Bredehoft, Tom Davis, myself, etc.. all run the MTR's. When we were on the Rubicon, the majority of the tires were MTR's of all the rigs I saw out there. The only two flats I saw were a BFG and a Super Swamper, all due to sidewall tears.
