My to date with 22017 Audi Q-7 has had 3 sets of defective tire. Always serviced at dealership, before servive even due, they informed me at 13,642 that my tires were throwing chucks of rubber. Good year tires warrantied but charged me $600 plus install and balance that I paid. At 23,425 miles the same even worse issue appeared on the 2nd set-- again good year warrantied if I paid another $762. The dealership, Audi sarasota, fl has been helpful but suggested I buy perrelli tire for another $700 plus dollars. Goodyear has a problem with the tire for this model, other owners have had issues I was told by the first service manager who has left the dealership. I would like Goodyear to return all monies spent on these defective and dangerous that works.tires and I will buy the appropiate brand and style. How should I go forward?

After 10K miles we started noticing abnormal wear on the outside of the tires. I have the 18" Goodyear runflat tires. The tires are chunking severely posing a serious safety concern for my family. Audi has a tsb for the same condition on the 20" tire. I do not know why the do not cover the same condition on the 18" tire??

Goodyear Eagle sport run-flat tires on a new 2017 Audi Q7 are completely bald on the front outsides and have chunks coming off of them by 16,000 miles. It was actually a problem earlier, but my current mileage is 16,000 so I'm using that number. It's a known issue according to Audi, but Audi of North America only passes the buck and says the dealership should deal with it. The dealership was the one that told me to contact Audi of North America.

Bought vehicle from dealer with 22K miles, as a previous two year lease vehicle. After owning it for four days, noticed loud screech in brakes when backing up and applying brakes first time in the day. Took to local shop, and they found brakes to be ok, and that there is a bulletin on this with no fix at this time. But what they did find is very uneven wear on my front tire, which we would not have noticed. They said there was a bulletin on this at the 14K mileage mark for tire replacement on the Goodyear Eagle. We were fortunate that the dealer we purchased from agreed to replace all four tires for us with continentals. No hassles at all. Could have missed the notice since it was a lease vehicle. But I wonder how long we would have gone without knowing this"?" if it wasn't for getting the brakes checked, we wouldn't have known. Waiting now for a fix on the brake noise. Kind of embarrassing when driving an expensive vehicle.

We purchased our Q7 Feb of 2017. It was a cpo with 10K miles. Part of the deal was they had to change he tires. The front tires looked like they were chewed up or tearing up. They changed the tires. Then about 2K miles later it started doing the same thing on the new tires. Same chewed or tearing up look. We took it to Audi. We had the Goodyear Eagle sport all season tires. They changed the tires again. Then same issue again about 1500K miles. So finally the GM placed new set of pirelli tires on all 4 tires. Now it's only about 1500K miles still doing the same on the new sets of tires. Audi claims that there's no issues and blames its the road that we drive. We've never taken it off roading or any dirt roads. Only regular street roads. A friend of ours that works a local tire shop and he says it's an alignment issue. I'm not sure if Audi have looked at their specs on the alignment and maybe off on the numbers. We also filed a complaint with Audi directly but they said they can't do anything for us. We also found out there's already a bulletin going on about the issue with the tires through Audi. But still no recalls.
