MPS4S - strange wear on one tire

[chimaera]

I noticed yesterday some very strange wear on my front right tire. None of the other tires are worn like this. only around 3k miles on the set, and one light autocross event almost 2 months ago. anyone have input as to what might be going on here? I am certainly not an expert, but from past experience, if it were an alignment problem, i would expect more odd wear on the other tires. and this doesn't seem to match wear patterns i have seen with balance issues either.

anyone else with MPS4S seen this kind of wear?

Stock camber + track. It's to be expected.

Looks normal for a PS4S that has been autocrossed, mine look the same (actually much worse). They get hot especially on that outer edge without more negative camber (not possible to adjust with the car's factory setup, front camber is fixed unless you get camber plates, lower the car, etc.).

sounds like i need to get those camber plates sooner than later! thanks for the feedback everyone

Are you sure you're not rubbing?

Seems unlikely since it is still at the stock height.

Rubbing is not only a question of ride height...

Tire size, tire tread width, wheel offset and spacers can all cause rubs on the stock ride height.

of course, however, all of it is stock...with the exception of course a change from the stock conti's to the MPS4S of the same stock sizes.

Which pretty much excludes rubbing as the culprit.

Looks like they're feathering.

Also, looks like they were run with too low of PSI.
