E90 factory suspension tune causes excessive wear on non-RFT??

xq_zhu · 07-05-2010, 09:19 PM

I switched to a set of Bridgestone Potenza Grid last year after reading positive review of it on tirerack (tested on a 328i). But after 9000 miles, I've been hearing loud noise when running.

Dealer checked and told me ALL 4 tires has feathered on both inside and outside, and suggest that I replace them all.

I have been maintaining the tire pressure and since all 4 are equally worn, I don't know if this will be due to an alignment issue? Or is it just that the factory suspention is tuned for the stiffer RFT?

The car has X-drive.

Definitely could be due to the alignment. What are the alignment numbers?
