I didn't even think about offering feedback about the PR3s in cold and wet, but I'm greatly impressed. On my ride home from Fort Worth in early May, I'd taken a "long-cut" so I could ride in the mountains. I went to Clayton, NM, camped and headed for Taos. Just west of Cimarron, NM, as I got into the mountains, the roads were wet. West of Angel Fire, it began to rain hard, and temps dropped into the upper 30s. The PR3s were fine.
Leaving Buena Vista, CO, climbing up Trout Creek Pass, temps were in the low 30s and dropping. Then about 20 miles from Fairplay, it started to snow and the temperatures dropped to about 23F. It had been warm the day before and so I made about 10 miles before the snow started sticking to the road. But the last 10 miles I was slowed down to 15mph. I saw two cars in the ditch, one a 4WD SUV that a highway patrol officer was stopped at. By the time I got to Fairplay, the snow was probably 1-2" on the road, and my pucker factor was at about a 10+. But the bike never felt squirmy or loose, even when I turned into a "drive" into a motel that ended up being a mud and gravel trail leading down to the river.
I had to stop and turn around. It was too narrow to U-turn in and I got off the bike. I could barely move without slipping and sliding, but the bike just moved where I pushed it.
I feel much better about the PR3s in questionable traction situations now.
