Tire pressure when it's cold

And Michelin have no reason to go to the topside of any potential savings do they? Not like they are trying to sell tires or anything.......
Oh yea, I'm a French Supermodel too, in case you haven't heard. Read it on the internet, so it must be true.

I will continue to run my chunky duals thank you. First time someone gets stuck in a muddy field with those wide tires, removes any and all advantages they MAY have in my book.

I had to get several of our drivers out slick surface mud with solid ground beneath. They didn't know how to drive those wide tires.

Slow and steady wins the race, but predict where you'll get stuck ad gas the heck out of it.

 

Y'all who over-inflate for more mpg over properly inflated tires, did you ever realize that your tires are now not gripping the road with the proper footprint they are designed for? Is one accident worth the $$ you so desire? What about liability? A sharp lawyer will place some fault on you for running over-inflated tires.

The only time to exceed the load/inflation table pressures listed is when exceeding the safe operating speed of the tire. Most modern tires are good to 75 mph. If you're gonna run faster centrifugal force deforms the tire and a harder tire will keep it's shape better.

 

I have less problem with wide singles breaking loose than I ever did with duals... at any pressure.

 

So where's that link ?

 

Lowered my XDA HT's down to 90PSI yesterday, and I run up to 40k on the drives. Will see if it makes any difference or not.
As far as grip, I get into some pretty nasty terrain, fields, job sites, and so on. Not always dry and firm unfortunately. The guys with the X Ones etc, need a pull long before anyone else does as a rule. Then we had one guy leased on here that went to them, and blew a tire in SD or ND. He had to sit on a ramp for TWO days until one of our other guys could get a tire to him as he was passing through. The tire came from Mn. Lost revenue alone would blow any cost savings out of the water....
Bob, don't hold yer breath mate, sometimes it's easier to find the wall for your head, if ye know what I mean?

From Michelin (I wonder if they know anything about tires?)...

 

There can't be any trucker that has all tires perfectly inflated at all times....there are way too many variables. Just be DOT compliant lol

 

Depends how lazy you are I guess. I know at least once a week, I go around all 18 with my tire gauge, a few times a week for the most part. If I wake before I can leave out, I go around with the gauge. If I fuel in the morning before leaving, ditto. I am normally sat for a day a week, or most of a day. I use that time to check tire pressure, brake adjustment, check every light on truck and trailer, lube up my binders, and any other little jobs I make a list of during the week.
