How much PSI are you running in your tires?

Reminds me, I need a new one, that will stay locked onto the stem. Maybe Fleetpride will have a good one. Short Truck stop cheap ones get stripped out, won’t stay on stem.

 

I got these air chucks from NAPA Auto parts.

I think Harman Heavy Vehicle Specialist will have them too.

 

And they lock on? Call me a chicken, but here's what I've done: You know the air chuck with the short rubber hose and the trigger with the built in gauge? I took off that short hose, and added a 25' hose to it, so I can lock it to the tire and hide while I air it up. When I was a mechanic in the Marines, they showed us a picture of an Air Force guy that was airing up a tire on a jet. It blew up, and split him in half from his crotch to his neck. Looked like hamburger meat. I've been scared of tires for the last twenty years because of it.

 

I like to run max pressure in the summer/dry and low pressure in the winter. At least with wide singles as they start to loose thier footprint around 95psi+. I want more rubber on the road in the winter. High Psi does tend to wear the tires unevenly but it saves fuel and the fuel savings trumps the cost of uneven (center) tire wear over time.

 

One good thing about using the glad hand on the Truck. I can’t over inflate them. Govenors set at 130, most the tires will ever go to is 110. Have to be careful at some Truckstops, can over inflate/ blow one out.

 

I use the sticker in the driver's side door jamb. Recommended pressures are listed there for steers and drives.

 

I do almost all the tire installation at the company I work for.

All the drive tires for dump trucks, tractors, cement trucks are at 105 psi whether virgin rubber or recaps. They wear just fine at those pressures.

425 Wide Base are 120 psi for steers on dump trucks and cement trucks.

My tractor is the exception for the drives because the Continental tires are wider than all the other 11R22.5’s we have.

They won’t sit flat on pavement at max pressure. Even loaded when they were brand new.

All the 255’s for stepdeck is 110 psi.

The 275 low pro, 115 psi for all the low boy trailers and the lift axle for live bottom.

The 11R22.5 trailer tires are 105 psi for all of them.

 

110 steers 100 drives

 

I know this is an older post but those aircraft tires are split rims so we used a safety inflator system with a stand-off. The rim blowing apart is what really kills. When I was young, dumb, and full of .... we decided to just over-inflate a tube by itself in a tire safety cage and when it blew the entire hangar vibrated and people came from other ha gars because they thought it was a real explosion. Almost got into deep shizzle over it until we played it off as trying the show the newer guys how unsafe it was and blah blah blah lol.

I am just like you, anything with higher PSI if it blows no matter what it won’t feel good. Checkout this vid, ain’t nothing to mess with.
