914World.com _ 914World Garage _ Tire pressure?

Posted by: Carlitos Way Dec 6 2004, 07:34 PM

Not to sound dumb... but the PO of my car had the tires at about 40 psi. That seems a bit high. Any suggestions on what a GOOD pressure should be for everyday driving? The car gets a little scary to drive over 50 MPH right now.

what do you mean by "scary"?

my 195/50 712's like upper 38 or so. pretty firm

I've always thought 32-35 psi was good for the street.

What does it say on the side of the tire?????

Because the car is so light---reduce that by 10-15% and you should have all the handling and ride to make you happy.........

i had the kumho 712's at low 30's for a while with that same logic. car feels more tight and on rails with 'em pumped up. your mileage may vary,...

What I mean by scary is... when I get up to about 40 MPH or above, it seems as if the car is starting to wonder. Not sure if it's the tires, or if I have a problem with the suspension. I wanted to eliminate the tire pressure as a possibility first, kinda doing the "easiest fix first" thing first.

So I'll drop them to about 34 and see where they go... and if it's still scary... I guess I'll take a look at the suspension to see what I find.

Thanks for your input!

it ain't the tires..

get it fixed! lift the rear end and try to pull the tires side to side (suspect trailing arm bushings)

Nathan, i run my falkens at 38 on the street, a little bumpy but they stick 10x better

Yeah... it seems all that is in order... but this week I'm working on a MC upgrade/320i caliper upgrades... might not make it to the fun run this weekend.
