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:
Well that SHOULD be obvious. Tire rubs are bad.
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. -

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.
