Popular Tire Shop Destroyed $1,000 Winter Tire
They called me to tell me that the screw damage was repaired, but when remounting the tire it can't hold air because of a huge cut in the sidewall. I looked over the tire before brining it in, there was no huge cut. I was driving on it with 37 psi in it.
I drive over to the Mercedes dealership and their tire service advisor said he has accidentally made the same mistake when he worked at the other popular local tire chain with 58 locations in the region. He said with these wide 325mm tires, when depressurizing them to dismount them, you have to wait several minutes for all of the air to escape, otherwise the bead will not unseat easily and the tire shovel on the tire machine that pushes the tire off the bead will slice through the sidewall. He said the tire will still dismount, so sometimes you might not notice until you go to remount.
It's $1,017.68 including tax at the dealership to replace the tire. I'm negotiating with the tire shop now for them to replace the tire at their cost.
I am going to the dealership for all future tire work.

- Costco has one all-season staggered combo for my 21" wheels
- BJs has none
- Sam's club has nearly only winter tires for my rears and no all-seasons that could make a matching set
Folks with 22 (you have my sympathy) and 23" wheels will continue to keep their local tire shop on speed dial...

The Best of Mercedes & AMG
A few years back when my GLS 450 was brand new, I had a rear tire leak while on the road. So I pulled into a tire shop and asked them to put on the spare, which of course was not a full size spare and thus the rim was different. Imagine my surprise when I saw the technician trying to drive in the long bolts for my alloy wheels into the hub (with a pneumatic rattle gun) in order to mount the steel wheel of the spare, which is much thinner and uses different/shorter bolts. By the time I was able to stop him, the long bolts were damaged, the threads in the hub were stripped, and the car was undrivable. After a tow back to the dealership, which was about 150 miles away and $3000 worth of repairs, including a brand-new hub, the car was repaired. Happily though, I sent the tire shop an invoice for the repairs, which they paid.

I physically hand my wheel locks and the correct bolts to the shop foreman. And my wheel-protecting socket. And watch them use it. Also wary of lifting points.
I don't do this at the Dealership because I trust this one. Not my last one, though.

That said, the repair kit I have is Dynaplug, which I have used successfully without the patch.
Discount Tire refuses to service tires that have been repaired without the Tire Two-step.




I had a flat in my S560 and I actually paid to have it towed to my mechanic rather than use MB Roadside because they would only tow me to the dealer...and I knew the dealer was going to force me to pay $500 for some terrible Runflat tire




There wasn't any resistance. They wanted to sell me the tires.
(Saved @ $250 plus mount and balance vs. Tire Rack BTW, although that changes.)
No need to drive north, I just have tires installed elsewhere. No need to worry about whether or not the dealer will do it.
