I own a Tyre & Petrol Station in Essex, England and over the last three weeks
we have noticed four CLS`s with 5-8mm across the tread, but wear on the inner sidewall of all tyres. One irrate customers tyre had actually blown out and he was lucky not to have had an accident. I decided to check my own CLS500 and although I had 7-8mm flat across the tread I had the cords of all four tyres showing. I contacted our local mercedes dealer and had the vehicle transported to them at a cost of £188.00.
They very kindly checked said vehicle and informed me that their was no fault with the car in any way. I asked what had cause the tyres to wear on the inner side walls? his reply "I dont know, I am not an expert, sir" I answered I am an expert but I dont know what has caused it. There must be a fault, again "I am not an expert, sir".
The upshot of this mail is to warm all CLS drivers to check the inner edges of all four tyres as they might be in for a nasty suprise. I have sent correspondence to Mercedes Head Office in the UK warning them of this fault and the possibilitys of fatal accidents if they do not alert the owners.

I have encountered the same issue with the 20" wheels. What some have told me is that the adjust air ride of the car cause the car to 'squat' at 60mph and the car actually rides with negative camber forcing the wear to the inner side of the tire. I have asked if other members have had this issue besides me but you are the first to bring it up. I only had 6,000 miles

Did you change your rims and tires or are they stock?
I have owned my CLS500 now for two years and am running on the second set of tires. At the 35,00 mile mark (20,000 on the current set of tires) I nced extreme wear on the inner tread of the front tires. The wear was extraordinary. The steel belts were actually showing through rubber! There was no indication in the steering wheel to indicate any probelms. The outer tread show little wear but the tread towards the innner side of the tire indicated severe misalligment of the front wheels. There was never any pull when brakinng and the car tracked straight both when braking or not.
Recommendation to all: Carefully whatch the wear on your front tires. Don't repeat my mistake.

I have the slight upgrade from the factory, ie 245/40-18 fronts and 275/35-18 rears on Michelin. But I have seen this wear on the standard 17",
without a doubt it is a problem (as stated above) with the camber of the vehicle
and not the Michelin tyres as Daimler Chrysler The Netherlands have just suggested in an E mail to me!
I still await an answer from Mercs Head Office in England.

You description is identical to my problem, second set of tires with about 20K miles on the second set of tire. Inner front tire were worn down to the the point of the steel belts showing. Never had any indication of misalignment...no pull at any time. I did notice what in retrospect was extreme tire noise shortly after installing the second set of tires, Pirelli P-Zero Neros. I did notice that the front edge of tread was wearing faster than the trailing edge but did not connect that to misalignment unit the I noticed the steel belts showing through.
I did not hit any curbs or otherwise experience anything that would result in an obvious connection to tire alignment. The car has always tracked straight and there has never been any indication in the steering wheel of any alignment problems. The repair documentation indicates that the dealer replace a pin nunber 000-330-0-18 when aligning the front wheels.
The alignment and tire replacement cost me more than $1000. I am very interested to hear if there are any other owners experiencing similar issues.
This is a great car to drive but the time it has spent in the shop for problems (rough transmission down shift, SRS light and other problems) the car has spend more time in the shop than my eight year old Lexus. Please comment.
