Just some of the stupid things I see

Bulldog, you do realize that if you operate a tire below max presure that you will cause the tire to over heat quickly.

I have seen alot of tires that have been brought into the shop because some one thought they should run at a lower pressure and cause undue wear. The usual response that they need a new tire is incredulous. But they have damaged the sidewall and made it not hold air plus worn the sidewall on the nearby dual so that you might as well leave a stone in there for 50 miles. I highly recomend to anyone on this thread not to test theories with inflation.

Be safe, keep it at max. Dont over inflate or under inflate. Thankyou.

You'll get better mpg with tires filled to max or close to max but you'll get a rougher ride. Psi builds up with heat so becarefull no to run on max psi and running in the heat with out stopping cause that psi can easily build up to 150 if you starting at 120.

 

Trucks and tires are designed to run heavy and most of the time you are. Alot of companies are running 110 psi now to increase fuel mileage. Like lovesthedrive said, it's not rocket science. The tire manufacturers have fulltime employees testing and evaluating tires. Fuel managers are constantly reading up on best tire wear and fuel mileage. Take what they say to heart.

Inflation is not the only thing that effects wear. Worn shocks, suspension components and alignment plays a big role.

Where's this chart you talk about Bulldog? None of them numbers are stamped on the tire which shows the numbers under normal load and max pressure. What's stamped on the tire is what everyone goes by.

 

Injun? quit poking my eyes with that stick.

 

I don't know what the manufacturer's recommend for your loads. I look at a tire/kick a tire and if it is slack I then put the gauge on it. Here's the OOS statement:

6) Tire has noticeable (e.g. can be heard or felt) leak, or has fifty (50)
percent or less of the maximum inflation pressure marked on the tire​

sidewall. (393.75(a)(3))

7) So mounted or inflated that it comes in contact with any part of the
vehicle. (396.3(a)(1))​

*NOTE: ​

​

​

​

​

An out-of-service condition exists only if the tire can be made to
contact another component at the time of inspection.
(8) Weight carried exceeds tire load limit. This includes overloaded tire​

resulting from low air pressure.

Manufacturer's put the 110 psi on the tire. I can't imagine a manufacturer saying to run it at 50 psi because it will wear better. I know on my pickup tires I run 44 psi in a 285 series tire. So I cant see running 6 more psi in a tractor trailer tire.

But if it floats your boat to do that, beware what could happen to the tire overheating, blowing etc.

 

Had another one today. This time it was a local driver, speeding and his license had expired last November. His medical card expired last September. Five current suspensions in my State, and suspended by two other State's. To top it off he had 4 active arrest warrants in my State. They ranged from Felony Theft, Child support, burglary, and Violation of probation/parole.

 

Just a walking ticker tape parade there huh?

 

Everyday is like a box of chocolates.

 

I'm guessing he didn't get a warning. How in the world can someone like that drive? You couldn't pay me to leave the house, much less get in a truck and drive around hauling freight. I'd be a monument of paranoid ineptitude. Some people.
