Tire Pressure

Remember what happened with the Ford Explorer, Firestone tires and low pressure recommendations to improve the ride. 

Maximum air pressure and hard ride just seems to me like its shaking the car up and might find a weak spot in the fiberglass on the rougher roads.

[quote=ranger3]I am on the same program as Joel. If I am at max gross weight I will inflate up to 32psi. But for my weekend driving I run 22-24 psi. If this were a daily driver and I were concerned about tire longevity I might run  higher pressure. But I like the softer ride and the improved cornering that comes with the factory recommended pressure.

Are you sure your handling improves with lower tire pressures?

I autocross mine and  have 255/60-15 Uniroyal GTS tires.  For AX purposes I use 35# all around and it seems to work quite well. Street use I will drop it to about 30. The comment above about the lower pressures for bias ply tires is correct. My 79 sticker recommends 24# min/30#max Front and 26#min/32# rear. The higher numbers were recommended for "economy".  The idea behind the lower front pressures (vs. rear) is to promote some understeer (intended to be safer).  On the street I run mine at 30 all around and it feels great.  Lower pressures will provide a softer ride and for street use the differences in handling wouldnt be noticeable.  But, I live in an area with lots of curves and hills, so I like the firmer feel and the way the car will handle transitions with those pressures.
