AMG GLS run flats?

Hi all,

I’m looking to switch from an X7 to an AMG GLS. The Mercedes rep I have been speaking with said that all AMG GLS models have run flat tires. I am having trouble verifying this on the mbusa.com site. Can anyone confirm if this is true? I will be getting the upgraded Burmester sound system and am planning on the 22-inch AMG multispoke wheels. Any validation on the run flats would be much appreciated. Thank you!

That doesn't sound right. AFAIK, they have always come with summer tires.

You cannot verify it because it is not true. You may be able to get some sets with run flats but they are definitely not on all. The 23's are only made by Michelin and Pirelli, neither are run flat. The factory 21's are Pirelli, also not run flat.

And as someone who had run flats on a CLS 450 I can tell you they are garbage and you don't want them.

Thanks all for the feedback! The rep helping me insisted that all AMG GLS wheels had run flat tires because they didn’t come with a spare…he even said he had double-checked with someone else to make extra sure! I trust y’all more than what he was telling me.

I’m concerned about the no run flats. The idea of getting a flat and having to wait for a tow truck isn’t super appealing. I’ll have to do some more research on this. I’ve had run flats for the last 10 years, and it’s been a real life saver a few times. Thanks again for the quick responses!

Tire plugs and tire kit would probably save you in most cases. If it doesn't have RF then it probably comes with the tire kit. Then buy some tire plugs too. You could also see if this might fit in the back:

The first thing I would do is to go somewhere else to source this vehicle. You are off to a bad start already. You clearly are dealing with someone who does not know the product they are attempting to sell you. I personally would never in a million years buy a car from someone who gave me such clearly false and verifiable information and then subsequently "verified" the truthfulness of said false information.

Something I suggest all players in this game do is purchase the First Class Wheel and Tire package for the duration you expect to own your vehicle. It's a MB branded product albeit deployed by a 3rd party but it will save you countless thousands of dollars and headaches. I have far exceeded what I paid with every car, especially my CLS which has had no less than 6 front tires and wheels replaced and no charge to me except a $50 deductible. It's also fully refundable at a pro-rated amount as long you don't have an active claim and it's also fully transferable to new owners with a couple pieces of paper.

I have a 22 450 which came with the factory 23" non-AMG wheels and I have a factory "spare" tire, an inflator and sealant. I can show you a picture of all three if you would like but this eBay listing shows the spare that I have. You can clearly see it does in fact exist.

https://www.ebay.com/itm/25662081819...saAutAEALw_wcB

And lastly, just as a blanket statement... if you are looking for any sort of "convenience" I would NOT buy one of these cars. As convenient they are not. Pretty. Comfortable. Safe. Fast if you get the AMG. All of this describes this vehicle. Convenient it is not.

I will point out that if you opt for the upgraded Burmester 3D sound system, you don't get the spare tire!

I think that's the only situation that I'm aware of where don't get the spare. Instead you get the Tirefit b51 which I believe is the inflation kit.

The idea of "runflat" is good, but how often have you been in a situation where the tire had 0 air pressure and you could not have aired it up with a portable pump to either continue your trip or get it repaired? I can count once in over 25 years where I had this situation and had I had a plug kit I would have been able to plug the hole, drive home, and then have it repaired properly. Even with a runflat if you drive it very far with 0 psi, it's going to need to be replaced and there aren't many shops that will keep a 21" - 23" specialty tire on hand ready to install for you. When I got my first vehicle with no spare I was slightly concerned, after driving several hundred thousand miles at this point I'm not concerned at all. I do carry a pump and plugs in the vehicles now but have yet to actually need them save for the single instance.

All excellent points .

I can't say I would never buy a car with run flats again because that is unavoidable but, I would never purchase a run flat tire when they wore out, nor would I accept a run flat as a warranty replacement. The ride quality and performance are both garbage. And when you are talking about a vehicle that weighs somewhere in the neighborhood of 6000 pounds give or take, I would never feel comfortable enough with a run flat tire to drive it in such a way that was the purpose of why I bought such a brash vehicle in the first place.

If it makes you feel any better, the new G45 (X3) has gone away from run flats! Not sure if this is the new direction for BMW but the masses have spoken!

Wow, I love all these thoughts and responses. Thanks everyone for taking the time to post! I’m getting much more comfortable with not having run flats based on these comments!

The 164 chassis came with runflats with the Diesel engine. The DEF filler was in the floor.
They moved the DEF inside the gas flap with the 166.version, so no more runflats.
Not AMG.

What did you end up doing about the run flats on your CLS 450, because I’m having problems with them now. they keep getting flats on bumps in the road & now the rims are cracking. I had 3 cracks. What do you think I need to do about this situation?

If your wheels are cracking, you might file an insurance claim. Identity an instance when you've hit a pothole and use the protection you've paid for.
Run flats have stiffer sidewalls, but I wouldn't think enough to crack a wheel without a major impact.
