Having worked for ProComp's parent company years ago and having specified ProComp tires for many builds while I worked for them, the two biggest complaints I consistently heard and noticed about their tires is fast tread wear and weak/thin sidewalls.For tires, I went with Pro Comp MT2s. Truthfully, I went this route because they are less money than others out there. Also, 4WP sometimes has deals where you buy 3 get one free. The side walls aren't that tough but they grip really well. I cut a sidewall on one of them with only about 500 miles on it. After the replacement cost, it's still cheaper for me to have gone with the MT2s over something else but the amount I spent is getting closer to what a better sidewall tire would have been.
I got my boss really mad at me by refusing to run ProComp tires that would have replaced my Goodyear MT/Rs, even though they would have been installed for free. He never understood when I explained the ProComps wouldn't stand up to the SoCal trails I enjoyed doing.
