yeah i here ya about the warrenty work!! i have timberline AT's and they are aewsome...they are 31x10.5 and the just feel like you are floating over mud and snow...its a cool feeling! the AT's i think are more practical for highway driving, thats why i went with them instead of MT's, the MT's are super noisey at 60km/h. plus highway driving kills the tread wear!!
