After doing a series of powerslides yesterday, I looked at my rear tires and noticed that the inside of the rear T-1s tires is wearing alot faster than the outside. Is this normal, or is it an alignment or other adjustment (i.e., camber) problem. I have aftermarket 18" wheels, if that matters, but the suspension is stock.

 

that is very odd w/o a lowered car. Normally, when you lower it, you get camber issues, I have not heard of it with just rims. However, if it is a real problem you can take your ride to a shop that has computer aligment, they can tell you if it is a camber issue....if so...a camber kit is in your future.

 

Rims may do it, but I know you aren't riding massive offset, so it's your camber.

After you got your car lowered and new rims, did you go in for an alignment?

You might need to get some crash bolts and what not to setup your alignment.

But remember, negative camber is good for handling.

 

If it is very normal with a lowered car becaues u will have negative camber after the car is lowered. Therefore, the inside of the tyres will go faster than the outside of the tyres.

 

its normal under hard driving but the difference shouldnt b that big, get an alignment to b on the safe side

 

This is not unusual even with a stock ride height car. If you are powersliding, you are draging the opposite side of the car in the direction of the slide and the inside tread is subjected to the most abuse. The stock care does have some negative camber dialed in.

 

I'm also not sure that the excess wear (especially on Toyo T-1's) isn't purely from doing the powerslides....

Tires and brakes are con$umable item$ -- especially if you abuse them....

 

even stock the C32 has slight neg camber in the rear. no matter if you are on 17" or 19" the rear tires will wear out faster inside. And for the front wheel you will experience the outside wear out faster than inside.

 

You may want to dial-out some camber. To do that you need the speedybenz Camber arms. Oggle is selling a new set for $200 that would work for you, great product and not a bad price.

 

the car doesn't roll too much when you power slide, not like taking corners on the track. I drive fast on the street therefore I need my 2 deg camber.

 

I wouldn't dial out the camber, but I WOULD take it to a place that will perform a race prep alignment on it and maybe try to corner balance the car. My C230 came stock with negative camber and I go through tires fast, and planning to lower it soo, maybe after a needed engine swap this winter if I can convince my wife it's all for the good of the car, and will have to get the alignment set up again.

 

I had a C36 in the past and my buddy a mechanic who mainly deals with race cars now told me this was normal for German cars especially Mercedes. You're fine. Make sure your alignment is good but what others have said.. your car is fine.. enjoy some more power slides before you replace them tires =)

 

Weird. Fronts are wearing badly on inner edge, and rears are perfect. Time for an alignment I guess.

 

Still using 17" tires in stock alignment setting, no wear evenly at rear, but wear at front faster outside, I think more camber needs to be added.

 

Corner harder all of the time or get the alignment checked.

 

Even on my stock C55 the car has negative camber from the factory. I get tire wear on the inside rear tires, especially on the right rear whichs its worse, this is because it is the primary drive wheel (engages first) the way the differential is setup. The dealership confirmed this is normal for the tire wear even with a perfect alignment.

To get better tire wear I cross rotate the rear and front tires (left to right, right to left) this way the tires get even wear. This also helps cut down on the feathering/cupping effect on the outside edge of the tire, especially on the front tires.

I've run both 245/35/18 and 255/35/18 in the rear on stock rims and the same wear happens.
