For fuel mileage your tires should be properly inflated, not over-inflated. The manufacture's load inflation tables show the proper tire pressure for the maximum load the tire will carry.

Over inflation is dangerous, especially when empty or lightly loaded and in inclement weather.

Why diminish all the benefits of pneumatic tires by over-inflation? Solid rubber tires aren't a desirable design to try to emulate by over-inflation.

 

Mine don't run hot because they are properly inflated for the weight they carry. When tires are over-inflated they wear more in the center and the edges start getting irregular wear from having poor contact with the pavement.

I understand 100 or whatever psi was drilled into many heads for many years and there was no internet to obtain proper inflation information back in the day and there's many hard-headed drivers out there.

Just trying to enlighten a few thinkers out here.

 

You don't need the internet to find what a tires recommended tire pressure is, it says it on the tire.

 

I paid 3400$ +my last set of BF with 450k miles for a new set of BF Goodrich, not bad deal at Love's TS in Mathew,MO+ low sale tax in MO. The BF are lasting longer than my original Bridgestone are cheaper ;for steering i use Michelin XZ3A only, imop the best steer tire.

 

I put 105 p.s.i. cause that is what is on all my tires. though in the winter I put 110 p.s.i. in. in the cold weather the tires seem to lose a few lbs, from the cold. I had my drives at 110- 112 recently.. the last 4 months & they have wore more in the center, but I wanted better m.p.g. & knew I was going to change out this month. some tire brands look like they are too low of pressure even if they are not. I would think 5 lbs over or under would not hurt. it is impossible to keep perfect lbs, for me. with weather crating increase/decrease in pressure.

 

It only has maximum load inflation pressure on the side of the tire.

Show me a sidewall that has recommended written on it and I'll eat my hat.

 

Correct. The tire has no idea what kind of vehicle it is attached to nor how much weight it is trying to hold up. The figure on the sidewall is only intended to tell what the maximum inflation pressure is for maximum weight at a given speed.

I run 35 psi in the drives my dually, but will air them up if I need to carry a heavy load. The tires are wearing perfectly,

 

Keep in mind that the air pressure gauge you guys are using is not accurate at all temperatures and air pressures .

A good gauge can be unscrewed and adjusted, but I have never noticed a air gauge calibration station at a truck stop.

If the gauge is accurate at 90*, it can be off by more then 15 psi at 30*.

 

The stick gauges i use are all close to each other but the brass one I bought off the cashier's counter at AutoZone for my car is off by over 5 lbs.

I'd love to find a master gauge to check mine against.

 

We had one when I worked at the local JB terminal.

It was a liquid filled gauge with a adjustable regulator. We always set it to 100 psi, then check the gauge and made the adjustment. Also need to keep the slide cleaned with a light coat of oil.

I doubt if many tire shops take care of their gauges.
