I have an 03 S430 with 17,200 miles. Last summer I noticed a bumpy ride at 30, 45, 55-65 MPH. I took the car to the dealer 3 times to no avail. I was told recently that the problem was not the suspension, but the tire on the right rear. Today, I purchased 2 new tires for the rear and the problem is still the same. Any suggestions???

not suspension related? seem wierd. you should of replaced all tires and started from there. its possible that the tire pressure is too much or just the road you are driving on is just uneven.

I believe it is a suspension problem because the problem does not move when you move the tires around or replace them.
