Just curious, I assume this steering holder was not driving for a major carrier???Injun Thanks this. -
Max pressure is the maximum pressure, as in the pressure which is not to be exceeded. It is not the recommended pressure, nor is it necessarily the ideal pressure unless you happen to be carrying the maximum load as listed on the sidewall of the tire.
The tire manufacturers have load & pressure charts on their websites.
http://www.michelintruck.com/michelintruck/tires-retreads/tireInfo.do?tread=XDE M/S*
Click on the "Load & Pressure" tab. Then click or scroll down to 11R24.5 LRH. That is what I run on my drives.
393.75 (a)(3) says nothing about 50% or less of the maximum inflation pressure marked on the tire sidewall:
HOWEVER...if you read 393.75(h)(1) you will note:
In other words, the 50% interpretation (wherever you are getting that from) is in direct conflict with the ACTUAL regulations IF the tire is properly inflated to the level specified by the manufacturer for the load being carried at the time of the inspection.
Well that SHOULD be obvious. Tire rubs are bad.
Look at the sidewall of the tires on your pickup truck. LT285/75R16 tires will have a maximum load in the neighborhood of 3750 pounds at 80psi.
So, if you are only running 44 psi in the tires of your pickup truck, you are dang near meeting your "50% of max inflation" OOS standard.
You can run 44 psi in your pickup truck tires safely because you are not carrying 3750 pounds per tire, so there is no need to inflate them to 80 psi. The less weight the tires are carrying, the less pressure that is necessary to maintain proper contact with the road. The same is true with large truck tires. If you are not carrying the maximum load, there is no need to run maximum pressure.josh.c and lostNfound Thank this. -
I told him he could now get it straight and now worry anymore. He stated "I wasn't worried about it. I knew I have had 2 of the warrants for 3 years and I thought they forgot about me."zebcohobo Thanks this.

The max on my tires as stamped is 65 psiLast edited: Sep 15, 2011

That is actually from the CVSA OOS criteria. 393.75(a)(3) deals with "flat" tire, so it is referenced there. 50% below the max pressure is considered flat.
I'm still haveing a hard time seeing your calculations. You have the lowest pressure at 75 psi, how is that less than 50% of the maximum 110 or 120 psi? So by your own admission, your not below 50% the max. pressure. Maybe you should contact FMCSA and CVSA and express your concerns, they can put it up for a rule change.Scalemaster Thanks this.
