Just a small note: the pressures in this chart are absolute, not gauge. In everyday usage (like talking about tire pressure) we mean gauge pressure - that is, the difference in pressure from atmospheric pressure.
Your overall point is well taken (the change in temperature doesn’t matter much), but the numbers will be slightly different. For example, a tire filled to 100 psig (gauge) will reach 106.496 psig at 100 deg F, versus 105.663 in the original chart (assuming 14.7 psia atmospheric pressure).
