Tire Pressure Vs. Ambient
I recently found that adjusting our tires to the cold inflation temperature base on the local ambient may not be the correct way to do this. Based on this info, the ambient temp for setting tire pres...

I wonder why the chart DOES NOT follow it's own rule at the bottom that says:
Tire manufacturers never recommend inflating a tire to less than the specified cold inflation pressure. The bead of an RV/commercial tire can unseat
if its pressure gets too low resulting in a catastrophic tire failure. The general rule of thumb is to inflate a tire to a proportionately higher starting value when the ambient tire/temperature is hotter than 65 degrees and to the recommended Cold Inflation Pressure value at temperatures below 65
degrees F.
The chart then shows that at a recommended cold inflation pressure of 100psi, or any psi, if the temp drops to 32 degrees, it says you should inflate to less than the recommended cold inflation pressure. If it followed it's own advice, the chart would stop at 65 degrees. :R
