How many PSI do you run in YOUR tires?

Simply for tire wear, is how I read it

Over inflated tires will wear the center faster and underinflated will wear the shoulders faster. The ideal choice is to use the smallest possible tire(max load=GAWR/2) with the highest tire pressure so they wear evenly. A good example of this was on the poorly engineered Audi Cabriolet S Lines which weighed a few pounds shy of 2 tons and recommended 46 psi in 40 series tires.

About 120,000 miles of tires at 45 PSI and not any uneven wear, on several different tires and cars-trucks running higher pressures for a decade. In fact based on my experience the tires will last longer, as well as the brakes and most other vehicle parts from hypermiling.

Yeah, after all the other criteria is met.

I can take a picture of all 4 of my tires worn in the middle at 46 psi.

LOL, you need to go around corners faster.

Cargoboattails- what % of your miles would you consider "highway" miles?

I couldn't say accurately, but mostly as I lived and worked off the highway. I'm also in a rural area with no much stop and go.

48psi.

I run 44psig in tires that are 51psig max.

Im curious, do cheapo tires with less advanced construction techniques and materials wear the center faster at elevated pressures?

I run 55+psi in tires with sidewall max of 44psi. A little bumpy!
