I noticed a screw in my tire when washing my car in my driveway, so I immediately swapped to the spare and brought the damaged tire to the local tire store just down the road from me that has 37 locations in the state.
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 doesn't even carry winter tires for 325/40R22
Selection is not the greatest as this is what I found for my area:
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
I hate how the tire availability still hasn't caught up to the demand (makes me want to never buy a car w/a staggered wheel setup again).
Folks with 22 (you have my sympathy) and 23" wheels will continue to keep their local tire shop on speed dial...

I recently put a new set of tires on my 2022 GLS 450. I've got the Pirelli Scorpions with a staggered set up. I shopped around at my local tire store chain, and then compared prices at my dealership. To my great surprise, the dealership was very competitive and so I had them done there. Occasionally, my dealership, and probably many others, offer a four for the price of three deal on tires. Had I waited for that sale, I suspect it might have even been cheaper. I was very surprised by this, considering that Mercedes is usually quite expensive when it comes to maintenance.
You will pay that $1,000 again in short order using the dealer for tires.
Definitely worth checking the dealer. in my experience, half the time they're cheaper than any other store.
Plus they have the best warranty, which includes mounting and balancing.

No, I don't believe it either haha!The entire place damaging your car. You must be kidding?
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.

All good reasons to Hover around the operation. As close as they'll let me.
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.
A plug by itself is not a complete repair. An internal patch in combination with a plug is the standard - each protects the other.
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've had better luck at the local mom and pops tire shops. Especially when the owner is always around. I find corporate or franchised tire shops that the employees are just there for the check and probably have little experience

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

My MB dealer sold or quoted me non runflat tires, even though the OE tires were runflats. 2010 ML Bluetec and 2019 GLC.
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.)

VERY few MB dealers would do that. Mine will not install anything but run flat tires.

My dealer in Maryland had Michelin Pilot Sport All Season that they installed on my SL400 a couple of years ago. You need to drive north a little ways.

Did your SL400 ship with run flats originally?
No need to drive north, I just have tires installed elsewhere. No need to worry about whether or not the dealer will do it.
