Stayed at Crumpler Mountain Resort again. Riding Pinnacle Creek outlaws again. First trip since the Governor shut down the HMT for COVID-19 last year - the very weekend I was there! Great to get back. First time in the KRX and what a pleasure. It snowed the Thursday I arrived. Friday was a take it easy party day. Saturday was a great fast 60-mile ride with the guys from Triad Trailblazers, including Bob T. (The maps guy.)

Videos are only from Friday. No way to video the Triad Trailblazers they are fast as hell. The ultimate professionals though, I always learn from them.

Looks like a good time. I'd like to make it up there sometime.

How do your System3 XTR 370s work? Would you recommend them for mixed trail-riding and rock-crawling? I'd like some Roxxzillas, but I think they would probably wear out too fast so checking out alternatives.

On some of the rocky trails that are vertical I noticed some tire spin in 2wd when climbing. Switching to 4wd cured that. Not so much on loose stuff, on hard rock. It's like the contact patch becomes smaller on hard rocky edges and the tires don't flex enough? Not sure how exactly to describe it. She's a big heavy girl and the XTR 370's are more of a mud tire than a rock tire.

I'm running 11 psi front and 12 psi rear. I didn't' try airing down we were flying at 20+ mph and nobody in that group wants to stop for someone to adjust tire pressure.

Every tire is a compromise, we all know. For me the XTR 370's are the best choice as the only hard rock I ride on is on the West Virginia trails. Everywhere else its dirt, hard pack, soft pack, or mud. I try to avoid mud but often its not possible. As far as looks go - the XTR 370's are impressive.

I saw the AMS M1 Evil tires in person on that trip. That's a great choice for a West Virginia tire! It comes in 32x10x15 and is 8-ply, non-directional.

I used to have the M1 Evil tires in 32" on my RXR XP4 1000 before I upgraded to the KRX. They were a great all around tire but not the best at anything, certainly not at the kind of rock-crawling that I like to do. I have 37" Maxxis Trepador stickies on my old rock-buggy, they look just like the Roxxillas only bigger. They also work ridiculously well in the slick and wet rocks where I play. I probably just need to get 2 sets of wheels and tires for trail riding/rock-crawling.
