Your loading changes as you go around a corner. The Interply Shear (cause of belt separations) can go up by 20% or greater when you turn a sharp corner and your morning tire pressure will change by 2% for each change of 10°F. With o psi margin that means that every day you would have to adjust the pressure based on that days temperature. Not fun so why not include a "cushion" of +10 % so you would only have to add air if the temperature dropped 50°F.


Understand?
I read John's post as saying fill them up to cold max to gain all of the reserve capacity available to you based on the tires. It makes NO SENSE to buy tires with extra capacity and then run them at less air pressure and not use the reserve.

I believe you're both saying the same things.....at least this time! [emoji16]
