psi?
my 240 is sitting on 225/40/18 ps2... the maximum psi is 51. any recommendations as to how much i should fill them up? i have them all at 40 now, should i fill them up to 51?

51 is the *maximum* allowable pressure beyond which the tire would disintegrate - why would you want to stress your tires that much? I imagine they would be bouncing off the pavement like basketballs inflated like that. Even 40 is way too high for a street use. Something around 30-35 should be fine - play with it and see what you like, paying attention at ride and handling.

Remember, as your tires warm up, the air pressure will increase as well. On top of that, add 1 pound of pressure for every 10 degree increase in ambient temperature. To keep that in perspective, during the summer months in SoCal, you can expect an increase of 3psi just from the rise in ambient temperature.

hey guys thanks for the input....
i know the recommmended tire pressure is inside the fuel door.... but am i safe to assume that those numbers are for the factory tires. the factory tires are 205/55/16 with a max. psi 44. the recommendation on the fuel door is 28 in the front and 32 in the rear... with my 18's should i use this recommended psi?

yeah... PV = nRT... with volume and moles held constant.... pressure and tempurature are directly proportional
thanks for the advice man-
