I live in the desert (palm desert) and the temps range from 100 to 40 degrees between day and night so it takes a toll on the tires I'm still running the stock advans any advice on what psi to use?

BTW I SEARCHED

 

I wore my Advans out 3 sets of tires ago so I cant remember what the max psi is, (45??) anyway I would set it for 5 psi less than the Max. and that would give you room to move either way.

 

I would stick with 32# front 29# rear. Any other pressures could just increase the stresses on the tires.

 

cool just wondering because of the temp changes on such a regular basis I figured we would want to set it a little low

 

When the weather is HOT you should inflate 2-3 lbs over the recommended pressure. I have 31-32 lbs is the rear and 34-35 lbs in front during the summer. During the winter I keep the tires at about 1-2 lbs above the recommended pressure (for a little better gas mileage). The owner's manual says to inflate 3-4 lbs above the recommended if you are going to do any prolonged highway driving in hot temperatures.

 

cool but that wasn't really what I'm looking for if I were to do what you are saying I would have to deflate my tires in the morning and night and re inflate them during the day everyday I'm in the desert the temp change is pretty big

 

Filling your tires with nitrogen will lessen the amount of change in pressure due to changes in temp. My local Costco has it but You may have to go to a truck stop to get it.

 

I'm sorry. I didn't know that you were referring to that drastic of a temperature change within the same day - my fault. I would say that you should keep the tires at 2 lbs. above the recommended pressure. Therefore, 31 in the back and 34 in the front.

 

Actually that is what you were looking for. What he was saying is that about 2psi higher will be OK for HOT driving and also works in the cold. Plus, as he said it should improve gas mileage slightly.

FWIW, I ran my Azenis at about 40F 38R both for racing and street driving.

Just dont vary the pressure from frt - back >7psi, or back to frt > 5psi or your frt will spin, respectively, slower or faster than the rear which is rough on the drivetrain.

You will be surprised on the effect that 1 psi has on the tire circumference.

Since you live in an area with a wide temp range, just keep the psi at the recommended owners manual specs.
