Tire Pressure
The door post pressures of 32 and 33 work best for me. I have less than 4000 mi on the red car and only 400 on the gold one and have the OEM Conti's on both. Anything over the posted pressure and it shakes my teeth out! And they are not false ones either!
My local dealer likes 40 psi for some reason they cannot explain to me. I had it there for a wash job and to program the second key they owed me for one they thought they lost and both times my tires were all 40 psi and it rode horribly. I found the lost key under the drivers seat a week later so now I have 3 expensive keys for it.
I don't drive the cars hard but I sure can't tell any difference in handling, only a much stiffer ride. I bought a new Conti for the wheel I scuffed and had repaired. Unmounted and standing upright I could not flex the tire by putting my 200 pounds on it. They are stiff tires! Other tires might respond differently though so I'd suggest 32/33 and work from there until you (or your significant other) can't tolerate the ride any longer.
A surefire way to tell if you have too much air in the tires is if your significant other can't keep em' in her bra! Lower the air pressure immediately!
I have nitro in the gold car and a mixture in the red car but haven't had them long enough to make a comparison. In the Air Force we used nitro but it was to eliminate or curtail a fire hazard if I remember correctly. Nitrogen is an inert gas.
