: Tire pressure question

On the door of my 07 escalade I believe it says to inflate the tires to 31 psi. I've always kept it where it's "supposed" to be. However it seems like my old tires were worn more on the outside which indicates too low of pressure. I just changed the tires and don't want them to wear unevenly. What do all of you keep your pressure at?

I keep mine at 38 PSI.

on 26s with 305/30/26 I try to be between 40-42 psi, like to keep them firm to protect the wheel from pot hole and road damage. blow out tire cheaper than wheel replacement (extreme situation)

Were they worn on the outside on all four or just the front?

Best way to check is the chalk line test. Draw a line of chalk across the tread on all four tires. Drive forward a couple hundred feet, and check the chalk line. Adjust your tire pressure accordingly so it disappears evenly from the tread.

Alignments are always recommended when replacing tires. Especially if they are wearing out unevenly. Toe can be out or caster.

35 is the recommended pressure. I keep mine at 37/38 also.

35 is the recommended PSI like people said. 50 is the max safety limit

I always inflate to 40psi. (filled cold, not after a long trip) Than forget about them till they hit around 33 than its fill time again. 31 is under inflated unless you were filling them back to 31 every couple weeks if not, than they got into the 20's which will cause premature wear on the sides faster than the middle.

In the past I had bad back issue and kept them at 30 for about 6 months until my back got better, you get a softer squishy ride at 30. I didn't like it but it was easier on my back going over all my city's pot holes.

<25 PSI Dangerous condition may arise
25-30 premature wear on sides, soft ride, bad gas mileage
30-35 Safe operating condition
35-40 Safe operating condition, harder ride, best gas mileage, least tread wear
40-45 Premature wear on middle section, very hard ride
>45 PSI Dangerous condition may arise

The door says 35 that is what they should be set at cold. In Florida they will raise to 38 when hot.A lot of time and research has went into ride, wear and handling from the factory. Just go with what the door says.
