Tire Pressure Vs. Ambient

And he's probably a French model too. Bonjour. ;)

This is what Maxxis says about inflation of the tires I use;

"...In order to accurately assess your tires’ inflation pressure, please note that inflation pressure should be adjusted and/or checked when the tire is cold or before driving for the day."

I call BS on the 65* baloney and adjusting for temperature.

Yeh, I have my suspicions also not knowing the providence of the chart.

On the other hand, it's right on the money based on my current ambient (90F) since the pressures have risen 5 psig and it was about 65F last time I adjusted the pressures.

I'm thinking I will use the chart since I can not see any harm. For example, I will be leaving when the temps are ~104 and within 3 days be in 60F temps. Worst case, be a little high but no chance of being low.

So you want to go with an "anonymous" tire inflation chart with no idea who came up with this theory and something that is not endorsed by any tire manufacturer?
Me, I'm going to follow the tire manufacturer's charts.

Sorry, Dick. As Tireman9 (a retired tire engineer) stated in that link, cold is
not at a specific temperature, but before driving, exposure to sun, etc at whatever the ambient temperature is.

I, also, would like to know the source of that "interesting" inflation chart that contradicts all the major tire manufacturer's written inflation instructions.

Sure looks like another of those "if you read it on the Internet........" things.
