Well,I had 4 flats with the Over Priced,Over Rated Run craps!!I kind of know where you're coming from, junkie, but I've had two flats in these c5's and it was kind of nice to keep going until I had them fixed. It's not a lot of fun having a flat in the middle of the Nevada desert with no cell phone service.
30 lb Everyday driveing is factory specs,35 lb for aggressive driving is factory specs!!One more thing comes to mind the door sticker missing off my car.. It has 275/40/17 on all 4 corners is the the standard setup from the factory for a 91 coupe?? Currently I am running 30 psi in them with no guidline other than it rides well and the sidewalls look right.. On another note when I have the tires changed i am getting a 4 wheel alignment any suggestions on anything other than the stock limits for good handling and straight tracking on uneven pavement we have lots of that in the northeast..
I'd add 1 deg + caster to my above settings,Set the camber all the way around at .3 Negative Camber,front toe at 1/16 in,rear toe at 1/8 in and run 35 lb tire pressure,Drive it and see how it feels and go from there!!Where would you set it for performance driving and HS Stability? I will bring it to a race car shop to have tires mounted and alignment done so if outside factory specs no problem... I am in the race car biz so access to them no problem and they can easily do 4 whell alignment thrust angles all that with latest of laser stuff.. I want stable hanling and thanks for the tip on the crown in the road though it wanders all over the place. The interstae pretty flat town roads big crowns and 30 mph speed limits.. 65 to 75 on interstae average..
