Air Pressure

[QWKSNKE]

yeah truck tires are a different class and are recommended to be run at a higher pressure.

Ford recommends the tires on my 250 to be run at 55-60 psi

The recommended pressure on my 1500 Chevy is 42psi, I believe. I run 60psi, though.

I run 37 psi cold in the '95.
Better fuel economy, and get longer life out of the tires.
During the hot summer months, I will lower it back to 35 psi cold though
Generally the hot pressures are about 2-4 psi more depending on the outside temps

If I run mine that high the centers would wear out in half the tire life. I drive to much highway speeds to be able to run any of our mustang tires that high

too low a pressure can wear out the tire shoulders prematurely too.... generally anything under 30psi on todays radial tires is too low ... sidewall flex and hard cornering will do it with low pressure. I run mine at 40 psi and wear them all pretty evenly and get better mileage? wear and mpg but sacrifice a little more harsheness in the ride. I don't like the feeling of driving a boat with sidewalls flexing too much

all just a matter of personal preference too. wife doesn't like riding in my Mustangs for a very long ride (over 10-15 minutes) because of the bumpity factor

It must depend on the tires. If I run any more than 30psi on my drag radials, then centers wear out waaaay before the sides. I have run 18psi in drag radials for a few thousand miles and never came close to wearing the edges out.

yeah ... drag radials a totally different construction ....lower pressure works better

You forget how much I drive per year (near 20k per all highway).
I have around 9k or so on the tires so far, and they seem to have worn very evenly.

Are you talking about your DR's?

Actually I was referring to any tire
