Procomp X-terrain ?\'s I am about ready to get rid of my swampers in favor of a more road friendly yet aggressive tire. Since I will be running 5:13 gears very soon, I need to run at least a 37" tire to keep my rpm's in the right range for towing/freeway driving. So, in my research for a radial 37" tire for a 15" wheel, I came across the Procomp X-terrain and the Parnelli-Jones Dirt Grip tires. They both make a 37x12.50x15 tire that is not too bad on price. I know several on this board are running the Procomps. How are they for wear and road noise? Right now I can't hear squat with the swampers once I am over 20 mph. I am looking for opinions and ideas please! Which are better, the PC's or the PJ's? For tire noise? For tread wear? Thanks guys! And Gals!
