: Feeling the bumps!

10-12-2009, 12:32 PM
1995 525i with 109,000 miles. Very little work has had to be done on this one. Got some new Bridgestone Serenities on it - great tires - feels great on the open road - but feel the bumps in the road - possibly the struts / shocks? Any thoughts?

Probably a good place to start. What size wheels are you running? Bigger wheels allow less sidewall and that makes for a rougher ride.

Not sure what your tire profile is on your car, but feeling every bump is just as often due to tire type and psi, as it is suspension. If you are running 17" tires bring the PSI down to 36 in front and 38 in back. If you are running 16" tires, bring the PSI down to around 32 front and 34 back. BMW PSI recommendations in general are a bit on the high side IMO. And, a few PSI lower on the tires can make a big ride difference.
