Just in case anyone is considering these tires now or in the future, thought I'd throw up a quick opinion of these.
I got a damn good deal on a set with lots of life left. Hadn't been beaten too hard. I know a lot of the trucks at the mines I worked for ran em, and they see some rough use on shitty roads, and that's it, hardly ever see pavement. They run em in a lot of mud, a lot of sand, a lot of rock, coal, brush. Well considering this I figured they'd be good tires.
Well even though mine use is hard, I guess my tires see worse.
It's been not 2 months now, one is garbage the other has a plug in the sidewall.
On the first trip out I stuck a thorn through the sidewall a couple inches down from the tread. It wedged itself against a shoulder lug and drove itself into the tire causing a slow leak. A simple plug and I was on my way. No one else had any problems on that trip.
More recently, about 2 weeks ago I was out in very remote Nevada on an old overgrown very narrow mining road when I cut a sidewall pretty damn good. Not sure what I hit but it trashed the tire. Also found another cut going down to the belts but not through.
Could be coincidence but I'm of the opinion these tires have weak sidewalls.
I've run from new:
bfg all terrains
and now 3 firestone mt's and a kevlar mt/r
I've run them all in very similar terrain. I did manage to put a tiny cut into the sidewall of one bfg but I pinched it pretty good between my wheel and a rock, and I was able to plug that to get off the trail. I also cut the tread right down through a tread block and into the belts of the tire on a bfg. But I'd call that a fluke. I think the procomp had 1 rock puncture through the tread that needed a patch. I can't think of any other issues.
The good news is that they're a dull roar instead of a high pitched whine like those god awful annoying treadwrights, so they don't bother me on the road at all in terms of noise. They handle well, they're wearing well, they hook up just fine. They seem to be good in the rocks, mud, and snow. Haven't had em for any winter driving but I can say so far I'm happy with them on road and off but they have terrible sidewalls, or at least that's my experience so far. I'd be hesitant to recommend them for any serious wheelers. Too bad to because I really like the looks of em.
