In Reply to: Correct Tire Pressure posted by Dave323i on September 23, 1999 at 22:13:25:
: I have a black '99 323i with Continental (I know, I wish they were Pirellis too) 205/55 16 tires. Door jamb says recommended pressure is 33 fr 41 rear. Seems I read somewhere to run them about 4 lbs above recommended for greater handling in corners. Am confused about effects of a little over vs. exactly recommended and how much over can I go without undesirable effects, etc. Can someone with authority please explain pros/cons of moderate overinflation and also settle question of "correct pressure?" Thanks.
It's for 4 people. More pressure does not equate to better handling. I run mine at 29f and 34r with a modified swaybar anchor point. The car now handles like a go-cart which is the way I like it. Bear in mind that stiffer suspension and higher pressure tire results in loosing contact from the road while its bumpy. The setup has to be a bit compliant to allow the suspension sticking to the road. Also higher air pressure in the front aids turn-in response, BUT up to a point. If the front tire become real hard, then the diminishing return is understeer because the car will push.
