Think I'm the unlucky one.
Changed my 12xd 9kmiles 20" Dunlop to Conti DWS a month ago from a local American tire shop in Bay Area.
Started steering vibration and pulling to right immediately . Went back for a rebalancing which did not help either. After reading some posts here, forced them do road force balancing. this seems to be ok at low speed, but anything above 65mph felt the vibration.
Thought of doing alignment to first rectify the pull, and ended up with east bay BMW dealer who did the alignment with min toe as per my request- but could never let the car go straight- even after 5 trips and equal# of redoing alignments, 3 weeks in their possession two OEM tire change to identify the issue led to replacing control arm to change the camber, counter balancing and a whole lot of other things which i did not understand like negative left numbers to compensate right pull....
May be because I started bugging about the status of the car every day,
they finally concluded(talked me into )new tires
are the culprit and asked to swap for a different set. American tire shop did swap for a different DWS set. Even after that nothing changed to pull nor the vibration.
All the numbers from the road force bal shows numbers below the allowable difference i.e less than ~026 inc- so no defect with tires
as per tire shop and BMW blaming on tires
. I don't understand any of those numbers either and just want to enjoy this 70k beast.
Do you guys see a pattern? Or just plain unlucky with these tires
? simply swap for another set or go Mich lat HP's ?
