I have Pro Comp MT 33x12.5 on my Jeep... I was running 33x12.5 BFG AT. The Pro Comps MT v/s BFG AT may not be a fair comparison, but going from the BFG to the Pro Comp was day and night.
On the highway, the BFG's were smooth and relatively quiet. The Pro Comps have always had a TERRIBLE vibration and are loud. So on the highway, the BFG is a MUCH better tire. However, off-road is where the Pro Comp impressed me. I've taken both tires over the same trails and I've been able to pass areas in 2-wheel drive with the Pro Comp, where I needed 4-wheel drive with the BFGs. Again, AT v/s MT, so it's not a fair comparison. What I would like to try next is the BFG MT's...maybe those will be the best of all worlds for me.
