Re: Tire Pressures

Modern High performance low profile tires with their stiffer sidewalls don't
need excessive high pressures.... actually you really want to run as low a
pressure as possible without rolling over onto the sidewall....  Testing at
the track with a pyrometer while setting up a track car... we found that
18 - 19 psi was optimum for that car with those tires... I was shocked to
say the least.... but it provided even temp. across the tire without any
rolling onto the sidewall.... and the car felt MUCH better on the track....
The pressures you run depend on the tires you are running more than anything
else...  suggested pressures in the manual are for the OE tires, if you have
18" rims and "R" tires it is going to be a completely different story....

Just my 2 cents
