OK...so I got caught in all this snow with my slides out. As of now, there's about 14" of accumulated snow and ice on top of my fifth wheel, with the slide deployed. I tried to get up there to brush...
Thanks to all who answered. I guess the general consensus seems to be everything should be OK. So once this confounded snow melts, I'll post again and let everyone know what problems I've had. Hopefully none.
I never gave a thought to the tires, but they were all brand new 2 years ago with whatever brand Camping World in Roanoke sells. I forget the brand.
