RE: [A/S] Tire Pressure and Nitrogen

I have a totally different view of tire pressure.

Recognize (as has already been pointed out) that maximum inflation pressures
increase tire life, as the higher pressure reduces flexing of the rubber
(which is the main cause of heat build up in tires) and the associated
damage.

Inflate your tires with nitrogen to the maximum pressure on the tire
sidewall (most airplanes and race cars use nitrogen) and the maximum tire
pressure will not vary very much - less heat and no moisture in the
inflating gas. [The "hot" and "cold" pressures become a non issue.]

So far as ride is concerned, modern tires are designed to provide "softer"
rides at higher inflation pressures (and less rolling resistance and better
fuel economy).

The ride of the vehicle is more a function of spring rates and shock
absorber damping characteristics than tire pressure.

So, tire pressure is a minor parameter, compared to what it was years ago
with bias ply tires and air inflation. Instead, go for improved tire life
and function.
