Three oe (3) Goodyear Wrangler tires, LT265/60 R20 have become defective, all in the same fashion with sidewall problems, two with bulging, one with an at speed blowout at the sidewall. First one, 1/22/16 while driving but stopped due to heavy traffic and another motorist pointed out the bulge. Installed spare, at destination purchased at full price 2 brand new tires in order to have matching tread on all tires. Dealer alleged there must have been damage, so there was no wear adjustment. Second one noted while vehicle was parked in my driveway 2/15/17. Called Goodyear who referred me to a local factory store who pro-rated an adjustment and I rec'd a new tire. Third one blew out at turnpike speed 8/16/17. None of these tires were anywhere near the end of tread life at the time of the problem. This vehicle has never been "off-road" and I do not drive around hitting objects with the tires. I do not want to turn over the latest defective tire to a dealer until I hear from you if an investigation is in order; it is "evidence". I did take photos of the first two tires and will do the same with the most recent one. Thank you.

All four wheels have developed cracks over the course of my six year ownership of the vehicle. I have spoken with the service director at simpson GMC of buena park, ca, numerous technicians at simpson GMC, service managers at America's tire of victorville, hesperia, and fullerton, ca and have hired an outside engineer that all agree that there is a defect in design and manufacturing on the 20' denali hd wheels (RPO: Pys). I have well documented interactions with all parties involved and I intend to prove the design flaw that exists with these wheels. I am also in contact with the media regarding the life threatening hazardous design these wheels pose to the public. General Motors has been advised numerous times of the safety hazard and problems with these wheels. Please reference the two latest executive office cases 8-1552109660 and 8-2402833027.

I have a 2011 GMC Sierra 2500hd denali diesel 4X4 pickup truck. At 60,000 miles one of the 20" aluminum wheels failed with a large crack on the backside of the wheel. I purchased a new wheel and had America's tire remount my tire. At 95,000 miles the same failure happened, but on a different wheel. This time there were two cracks in the wheel several inches long. On this failure I notified my GMC dealer, simpson GMC in buena park of the issue. I replaced this wheel again with a new wheel. Now at 115,000 miles I have a third 20" aluminum wheel that has failed. This time there are four cracks, 2 of which are over 1" long. I took my truck into America's tire and my GMC dealer and both a technician and the service director at simpson GMC are surprised the wheel didn't come apart while driving. I have attempted to work with my GMC dealer as well as General Motors corporate towards a resolution of this safety issue. I have asked GM to replace at least this latest failed wheel and investigate this matter further. I can't be the only one with this issue. GM has denied covering the cost of a new wheel and has twice now ignored my requests for an investigation. Because this is a huge safety issue where a failure could endanger my life, my family's life, or the lives of innocent motorist around me I must file a complaint and ask once again that my concerns be validated. I am asking GM to replace all four of my wheels with new wheels of the same kind if they can assure me this problem has been fixed, and if that is not an option, I am seeking General Motors cover the costs of four aftermarket wheels. If no resolution comes from this complaint I will file additional complaints with General Motors, the bureau of automotive repair, the BBB, the attorney general, and finally with my legal counsel.
