I put the FF SZ50 EP's 285/40/17's on my SS and was wondering what air pressure people are running in these.

think you should be running what the GM recommends...I run at 30 PSI on the Nitto's NT450, give or take a pound or so

It's been my experience that softer pressures aid dry traction, while higher pressures are better in the wet. I used to run 32 in daily driving and pumped up to the max on heavy rain days.

I agree with Ken. You need a little more in the front because of the extra weight. I am running 32 in the front and 30 in the rear.2002 Electron Blue Vette, 1SC, FE3/Z51, G92 3.15 gears, 308.9 RWHP 321.7 RWTQ (before any mods), SLP headers, Z06 exhaust, MSD Ignition Wires, AC Delco Iridium Spark Plugs, 160 t-stat, lots of ECM tuning
