Nope, I've never run an interco tire, but I have plenty of friends who do. They're tough tires for sure, but my rig doesn't weigh much and I'm more concerned with traction than strength of the sidewall. But that's just me.
I just see a lot of people on forums recommend the SSRs as a great offroad tire without considering the terrain they'll be used on. The best Florida tire is far different from the best Utah tire. You catch my drift. I think there are better options traction-wise for our terrain here in Utah. Not meaning to diss intercos, just making sure killshot did a little research before dropping $1000 on new tires based off someone's advice from across the country. Just trying to help killshot out. Feel free to ignore me.
