Chevrolet dealership in gaylord, Michigan installed dunlop AT20 grandtrek P245/75R16 tires on my hd 2500 Silverado pickup truck. This truck is a 3/4 ton pickup. These tires were passenger tires rated at 4 ply and never designed to be installed on a 3/4 ton pickup truck. I was not aware of this until June 2014 when I learned this from the Goodyear tire Corp. After they sent me to have their tires inspected. My truck requires lt tires and at least 10 ply. Chevrolet dealership in gaylord made my truck unsafe and dangerous to drive. One tire eventually blew out on the expressway, fortunately a motorist I was passing pulled up along side us and signaled that we had a problem up front at the passenger side wheel area! question is, why would a Chevrolet dealership not know what tires to install on their own Chevrolet Silverado pickup trucks? I asked them to put on the correct tires ( 10 ply - lt tires) according to the placard located on my drivers side door at no charge but they refused now what action is to be taken against a dealership who would do this" I had lt tires on the truck back in June of 2010 when I pulled into this Chevy dealership to have one tire repaired because of a slow leak. They talked me into buying 4 new tires and these are the ones they recommended and I agreed to. I did not know that these were not designed to be used on a 3/4 ton pickup truck. I had 75K miles on the truck then and to make matters worse they gave me free rotations every 6 - 8K miles without ever telling me they had installed incorrect tires on my truck! this is a nightmare! what do you suggest I do" GM has been zero help in this matter!!!!---I've tried but they are worthless! and this dealership is pathetic that they will not acknowledge their mistake and correct it by refunding my money back! I could have been killed or another motorist or seriously injured someone.

Consumer stated while driving on I-66, around mile marker 58, the tire blew out. This happened at 6:45 am. Consumer felt the steering wheel shook, and he felt the rear of the vehicle would fall. This was the driver's side rear tire. The tires had been rotated approximately 2 weeks ago. The tire was previously on the front driver's side. Consumer had a picture that he will send in. The entire sidewall blew out. This occurred on a 2004, Chevrolet Silverado. This was the original tire for the vehicle.
