I drove in alot of snow this year, since moving to Pinedale, WY. I only slipped once on ice pretty much because I was goiing a little to fast thru a turn. My tires were 10 ply because of all the rocks in the dirt roads up here. I passed my Avalacha on to my son so he could have a good car to drive my month and a half grand daugther around in. the tires barely look worn. most of the miles I put on them were highway miles, driving from Mississippi to New Mexico and Southern California. I just bought a F-150 and the Perrilli's are coming off soon becasue they are only 6 ply. They don't like rocks. The SilentAromor loves them..
