MY tires are rocking at 38 PSI
my dad told me to keep em at 36-37
But its cold as hell and i need gas milage,

What PSI should i have at each season?

is this cold PSI or Warm PSI......yes there is a significant difference

Even if it'* cold, you wires will warm up, especially if driving at high speed / long distance.

Keep the tire at the psi which is listed on the dr. side door or the owners manual. A good running engine will be the best way to get MPG'*.

i set them all to 34psi since its real cold outside
and it said 30

Adjust them to the recommended inflation pressure of 30 psi (cold), and forget about it. : ) ya can't go wrong.

Moving to General since this is not a mechanical problem.

what is rated on the drivers dorr (30psi) is the optimum tire pressure for safety, tire life and fuel milage

30psi is to low for a good amount of tires, you can just see it, and feel it.

I run 33 front and 32 back, cuz the car is lighter in the rear.

I run 35psi, and I still think that'* too low, at least by how the tires look.

A friend of mine asked me if he should fill his to 44, because that'* what his max pressure ON THE TIRES said

And comfort. If you want fuel mileage, you can run 35psi (cold) safely.
