Is It OK To Deflate A Hot Drive Tire On My Truck?

Oh ok. I get it now. Yeah, I see.

I think in your case it's probably best to deflate empty trailer tires to the minimum, and then inflate them when you get loaded. But not inflated to the max, just enough to meet weight requirements.

Then immediately deflate when your empty again. But, since you can't deflate a hot tire, you'll have to set until the tires cool. Then you can deflate and know your PSI is correct.

 

We won't see you because we're 10 hours ahead. We stay on top of these things already, and don't make mountains out of mole hills.

Your post reminds me of another member you'd probably get along with well.

 

Air the tires up when "cold", at start of day and leave them alone. "People love to complicate their life and then justify the complication".

What benefit do you achieve by deflating tires? Imagine yourself in court, on the stand, and telling everyone your theory and why you dropped air pressure and you didn't mean for the blow-out to harm anyone, but here we are in court.

 

No. But they can for a few reasons.
1) they were run at low psi, high heat stress in the past.
2) casing rupture due to prior curbing or the psi is so way over like 20 psi over at cold and a bad pothole or road hazard is hit. Doesn’t have to puncture it to cause what we call a casing concussion.

Here’s something to pondor. Look at the “construction patch” on the sidewall. The place were it gives you the number of plys and the materials used. Look at a Michelin for example. Look at a 14 ply LRG. Then look at a 16 ply LRH. You will notice they say the same exact thing. They are the same tire. Built the same. Weigh the same. Yet they are rated for different load ranges and weight capacities. Why. The extra 20 psi cold put in thru the valve stem.

 

@PianoManCJS the bottom line is this, if you run all your drives and tandems at 105psi up to sidewall max cold pressure, you will never have a blowout due to pressure. Run your steers between 110psi and max sidewall pressure. Sounds to me like your heart is in the right place, but you're definitely overthinking things. Set it, check it on the regular and forget it, you've got more important things to worry about on the road. On a related note, when setting pressure, set all the tires on the same axle to the same pressure.

 

The problem is you don’t have a unique situation. This is overthinking.

you don’t get that the number one reason why tires fail is under inflation.
