Just put on 4 new General Altimax HP 255/60/17 on the four corners. Wow, what a difference in ride & noise. I knew the GYs were a bit noisy, but it's like night & day. I have these same tires on an 02 530i I have and I really like them. Tough to beat price wise too, $588 installed and a $50 mail in rebate too.
