I love em! I had the Nitto dune garpplers in 37s. They performed better out in Glamis at the desert but didn't work well in mud or snow. The performed horribly in the rain; I was all over the road. But the Procomp Xterrains do pretty well in all environments. I don't do anything extreme but I usually go to Glamis and Big Bear a couple times a year. I hit up the mud too and have yet to get stuck. Regular road performance is fine as well. The Xterrains come in 2 ply and 3ply - I went with the 3 ply... a little more exspensive but a better tire.
I'm gonna start on another bumper after the holidays. I was gonna make a front but I guess I could do a rear one. I was going to change some things just to try something new. A co worker is beefin up my computer with some CAD programs, photoshop, shape, etc. that will help me in the design process. No more sketches by hand or using Microsoft paint. I'm gonna make it just to make it. I'll post pics. If you like it, we can work somethin out. Have any suggestions in what you want in a bumper?
