Cool Re: Is This Tire Pressure Chart Legit?

CAPRI RACER!

Scroll down to Table (3) in this link....

It is similar to the blue one linked to here, and discussed above:

https://s19526.pcdn.co/wp-content/up...tion_chart.jpg



The explanation following my first link explains how such a chart might be used - for adjusting tire pressure in an environment unlike actual operating conditions! - IE: a WARM GARAGE DURING COOLER AUTUMN OR WINTER OUTDOOR TEMPERATURES.

Think about it - it makes sense after reading the explanation that follows my first link-to.

So if I did regularly garage my Honda Accord(recommended tire pressure 32psi) in an attached space that was heated to, IE, F60°, and the January avg. dawn temperature was F20°, it would behoove me to set my Acccord 'cold' tire pressures to 36psi while in that heated garage.

Once I drove out of the garage, the tires would 'settle down' to, approximately, the Honda-recommended 32psi.

Makes more sense now! Too bad the providers of the blue chart did not make clear that intended purpose. Duhhh.. It implies an enclosed service space heated to F70°, and calculates pressure recommended to compensate for setting it inside of said space, before driving out into lower ambient temps.

Actually, it works out for the better that, in reality, our cars reside in our driveway, so no worries about cold-vs-compensated pressures. Just go outside at dawn, regardless of outdoor ambient temperature, and set to carmaker recommended cold pressure. If that pressure is too high, remove air, if too low, add.
