Does anyone know off the top of their head what the ideal air pressure should be for cold and warm weather for a 2005?

 

it depends on the tire.

 

Its just the stock tire. Should the pressure change between summer and winter or should it be kept consistent?

 

The tire pressure specs are inside the drivers door, but off the top of my head i'd say 32 or 35 psi. The tire pressure is listed as "cold p.s.i.".

 

32 and you'll be just fine. follow the oem specs for stock tires. now as for performance tire with a softer rubber compuond they do sometimes require a higher cold psi pressure due to them bieng soft. One guideline i tell my customers with aftermarket tire look for the max pressure on the tire and run 6 to 7 lbs lower. tire pressure will increase from 6 to 7 lbs when warmed up.
