So far i can not complain about my madddogs. i have the 39.5 14.50 17s . they have gone on a few snow trips an have done very  well. a few run in the rocks an have done pretty darn good. and of course i have driven them around town an they are awesome on road. in the rocks i did see a little more tire spin then i would have liked to. but they do hook up quite well.
