Lately I noticed the ride on the ml350 has been pretty rough, each time going over a porthole, its very bumpy. So I decided to check the tire pressure, I got 33.5psi for both in the front and 35.5 for both in the back (note: these are warm tire psi). I decided to lower them to 31.5 and 32 respectively. So what psi is everyone else using and how is the ride?
ps: sadly, airmatic is not equipped on my parents car. =(
