E93 Negative Camber tire ware

khaleel · 01-13-2016, 01:49 AM

I bought My E93 335is in May.
the driver side front tire developed uneven ware over the past 7 months, more on the inside than the outside. No issues with the passenger side tire.

I got all 4 new tires replaced with Michelin pilot sport this weekend ant took it in for alignment at an indy shop here in bay area (Auto Innovations). They have good reviews Yelp.
The guy was told me that the alignment is not off enough to justify left tire wareout more than the right tire. He also told me that the camber is off on left tire slightly and cant not be adjusted

. See the attached sheet.

Any inputs as to what may be wrong and how I can resolve it .
One more thing he did not reset my steering angle sensor does this matter ?
Is it okay for the caster to be off so much ?

How bad was the wear? Were your tires nearly worn anyways? If you do alot of highway driving and your roads are crowned that little bit of negative toe on your passenger side could possibly lead to a bit of inside tire wear on the left.

Tech was right, nothing in those numbers to indicate your tire wear problem. He's not totally correct on the front camber not being adjustable. You can remove the pin at the top of each strut and push the strut top in enough to gain about 0.5 degree more negative camber. I always do this, as you cannot get enough negative camber up there to cause a wear issue, and the slight increase in neg camber might improve handling just a bit, as it tends to reduce understeer.
