The MT/R’s weren’t very good on wet roads. I had a near accident with my mechanic (at the time). We both slid past each other as we crossed a cattle guard. There must have been mere inches between us. Good thing I was in a TJ and he was in an XJ. We were narrow enough to avoid colliding. However, my MT/R’s were near the end of their lifespan, so I’m warming up to trying them again. On a 17” wheel they’re one of the few with load C, and I always liked the Kevlar sidewall, especially now that I run without a spare. I might see how siping them helps with the wet and snow if I decide on this tire.
I’ll keep looking at the bosses. Not having to balance them would be a huge plus. That would indicate a well-built tire.
