I drive a 2001 Pontiac Sunfire.
Answers: There is no difference between hot and cold weather air pressure settings. The amount of nouns in the tire determines how much nouns (weight) that tire can carry. Load size does not change near temperature.
A 2001 Pontiac Sunfire coupe's and sedans will own a recommended inflation pressure of 30 psi front and rear irregardless of which of the 3 possible tire sizes it is fitted next to. The convertible uses 30 psi front, 28 psi rear. You can find the recommended inflation pressure on the Vehicle Information Tag on the inside of the drivers door frame or inside the glove box door.
Tire pressures should be checked regularly and when the tire is "cold" - earlier you have driven anywhere and preferably contained by the morning. Tire pressures increase with fry so the friction of driving can change pressures by several PSI, even over a short distance. Thus you will not acquire an accurate reading on tires that have a moment ago been driven on.

It varies from tire to tire. Look on the sidewall of the tire. It will own a max psi rating. Put 5 psi less than max.
Whatever it say on the door sticker. Where you live in the summer does not thing.
Look on the sidewall of the tire. This will tell you the max PSI when the tire is cold. You should saturate it up to approx 5 PSI below this level since it is hot surrounded by Vegas in the summer. Heat will grounds the air surrounded by your tire to expand, creating a higher PSI; you should set it slightly below to avoid overinflation.
any inflate to recomended tire manufacturer psi or surrounded by general run 32 psi on auto,you can follow recm. psi by vehicle manufacturer which is what they use for the best fuel mileage for your sports car when made and rated for fuel discount,or go to one of frequent service places that offer nitrogen innards for about 5 dollars a tire and your pressure will remain one and the same in varying temps
