I replaced with same tires. Was very smooth before replacing. I made tire dealer replace entire set, still very rough. Had them trued ,still rough. When car is off the ground and spun up very smooth. sounds like a suspension issue?How can i prove to the dealer(have extended warranty and service contract)
I am experiencing a rough ride on new set of tires on 2007 BMW 750Li
Would it be possible to swop tires and rims with another BMW similar to yours at the dealership that does ride well or swop your tires and rims to that car and see if it then rides rough.It's strange it happened with only a tire change, it's hard to comment without being able to drive the car first hand.
