GL Owners! How often do you replace your tires?




A gentlemen came into my business we got chatting and I noticed he had a MB Key. I asked him what kind of Mercedes? He said "I have a POS GL550 4Matic and I hate it" I reply with "Sorry to hear you have a lemon. Sounds like it was made on Friday?" He proceeded to tell me his car has no issues but he hates it because he has to replace tires every 16,000 miles and how he is going to trade it in on a full size Yukon instead!
It sounds like to me the dealer is racking him over the coils! I have had Mercedes where my tires last for 30k miles! I think he is either miss informed, bad alignment, dealer is taking him for a ride or he has really cheap tires on a premium car. Sound normal GL owners? It just seems very hard for me to believe.
How many miles or how long do your tires last?
Combine that with a relatively obscure tire size with limited options that tend to be soft tires that wear fast and it's pretty normal to see 15k to 20k miles. A buddy of mine with a 550 was having similar issues and bought new wheels and tires to go to a more common size and went with some Michelins with a 65K warranty. He's at about 35K right now and they are holding up far better than previous tires but down to about 30/35% and probably won't make it to 65, but he'd be ecstatic seeing 50 which is pretty likely.
Properly working suspension, correct alignment, and balanced wheels would help your tires to last longer.
if not rotated your right-hand side rear will go first, followed by left-hand-side front as you are running open diffs and most of the time the rear right-hand-side is the wheel with the most torque applied to it followed by the front left-hand side one.

My first set of Contis lasted 30,000 mi, second set of Michelin lasted 31,000 mi, I'm on Hankock set now, very happy with them, low noise and great handling, it looks like they will exceed 30,000 miles but I am selling the car in November when my new 350 comes in.
Looks like Dunlop doesn't make them anymore, so I'll have to shop around for something different.
If he like the car but hates buying tires I would tell him to sell the 21's and get some knock-off 22's. You get the same look with MUCH better tire offerings.

More weight? The 550 doesn't weigh that much more.
Only soft compound tires available in 21"? That's got everything to do with it. Get different wheels.
Or just accept the fact that you will burn through tires. After all, you knew it was a costly car when you bought it, right?
For me, the 450 is bad enough. I couldn't imagine getting just 16k miles out of a set of tires. I would shoot myself and the car, not in that order.
Others on here have posted that non run flats help with the Airmatic "wobble" which would be nice and is my only beef with the car. I am going to carry a plugging kit, three cans of fix a flat, small compressor and give it a whirl.

To resolve premature, costly inner edgetire wear, K-MAC manufacture a front Camber and Caster adjuster kit and also arear Camber kit. Rear includes extra toe adjustment to compensate for thenew found Camber adjustment facility!
Kits provide precise adjustment andimprove traction, braking and steering response.

While I appreciate your shameless plug I would be careful suggesting that people get rid of the negative camber that is built into most European suv's. It's there for a reason and making any adjustment to remove it would effect handling and safety.
The better answer is to rotate your tires and keep them at the right air pressure. I would also recommend buying a tire that is designed for these cars that have a lot of negative camber built in (especially in the rear). I have Firestone Destination ST's on my GL and Vredestein SUV Sessanta's on my Q7 and both have much more dense inner lugs to prevent inner tire wear on SUV's with a lot of -camber (BMW, Range Rover, Audi MB etc.).
The only time I have ever used camber plates to remove excessive negative camber was when I lowered my BMW and had to in order to get it back to near OE specs. I would never make this type of adjustment to a stock set-up and do not think it's a good idea to make this suggestion to folks who may not understand the implications.





“Get rid of”
No ,certainly not. Our intention was simply to make owners aware/point out that at K-Mac we manufacture precise front and rear Camber, Caster, Toe adjustment facility for virtually all model Mercedes- to finally allow accurate adjustment.
So settings in most situations can be returned to within factory specs.
Currently many owners blame the alignment shop when as we pointed out the only facility that they have to work with is front and rear Toe adjustment or one position offset OEM bolts!
