Hi everyone,

I recently got the tires changes on my brother's C230 and saw what the old tires looked like and was pretty shocked.

Is inner tire wear a result of bad toe adjustment??

Sucks that these were only a year old

Negative camber. Excessive toe-in/out would just increase general tire wear.

This occurs even if the car is stock suspension?

It doesn't look too aggressive to be out of the norm. Don't suppose you could figure out what the stock camber specs are on his car? Or more info about his car to dig around?

For reference, my E92 chewed up the inside lip well before the outside was close to finished, and it didn't exactly have the most aggressive stock camber specs.

Actually, you are incorrect on toe wear. Excessive toe-out wears the inside shoulders whereas excessive toe-in wears the outside shoulders. Excessive negative camber also does the latter, but incorrect toe settings will wear your tires out faster than a relatively incorrect camber setting.

+1. Everyone thinks its camber that does it but while it may have a small effect, I've read toe makes a much bigger difference. It makes sense if you think about it.

With toe, you are essentially dragging the tire over the pavement while rolling, therefore increase wear. Camber you are rolling on the edge more, but not dragging.

For a street car, you don't want any more than 1/16th total toe between the two sides (I think it is that, might be 1/32nd total). Where as camber, you can go up to -2 or -3 with no toe and your tires won't wear to badly.

Tire inflation also plays a factor (over-inflated means center of tire wears faster, underinflated means the sides of the tire wear faster).

So if you have poor inflation, lots of toe and camber, you can really destroy your tires. The OPs don't THAT bad, just enough bad that the toe was probably incorrect.

This would only be true if there was 0 camber and the tire was sitting flat at all times while driving. Likely there was a little negative camber (okay) and too much toe, therefore the inside of the tire sees the damage from the toe.

Thanks everyone! So I should get an alignment and correct the toe
