Bought a set of Cooper Discovery HTs only have about 20k miles and the tires are flaking and chunks of the tread are coming off.. The truck is driven on paved roads, alignment is great, air pressure is always kept in check, rotated on a regular basis.. suspension is fine. I dont take it off roading at all.. Took it into tire dealer they think its the tire since all 4 are doing it. Cooper customer service rep said its my truck causing it... anyone else think this lame??? ha ha
