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.

Bought a set of federal couragia mt's about five months ago still about 95% tread when two of the tires split going down the interstate. I have read all over the internet about this happening to other people with this tire in all different sizes. I also took the tires back to the company I purchased them from ans they have had a few sets brought back in the past month. Federal so far has refused to credit anyone for the issue. The tires are clearly defective and need to he recalled before someone gets physically hurt driving on them.

Kumho tyres on my Chevy Silverado developed sidewall splits due to dry rot. Tyres are only 1 year old and have 26,000 miles on them. They did not want the dot numbers. Contacted kumho and they said they weren't concerned. My auto shop said the tyres were unsafe to drive and replaced them. The indifference and rudeness of the kumho customer service person charles and his supervisor was appalling. Absolutely no concern that this could create a potentially fatal tyre failure. Very disturbing and quite a surprise.

Prior to purchase of the vehicle a vibration and bouncing was noted on the test drive, the dealer assured me that the problem would be corrected and two days later they replaced the tires. This did not eliminate all of the bouncing, the dealer again serviced the vehicle, the salesman and the service manager both rode with me in the vehicle and agreed that there was a problem and that it would be corrected even if all of the suspension components, wheels and tires had to be replaced. One day later I was told that the bouncing was characteristic of the vehicle and that there was nothing they could do about it, no other solution was offered. I do not feel the vehicle is performing correctly and is not safe.
