That makes perfect sense because the pressure gauge reading is off by the same amount in psi no matter what the tire pressure is. It is not a percent change like it is with temperature at different...

As was mentioned earlier, if you are referring to the Michelin chart, those are the minimums that will carry the weight and I assume a bit of safety factor. Most have found them too low for tall...

Your observation of how people see hot and cold is likely why they specify cold, as it it just ambient temp, no matter what it is. Hot would totally depend on the too many conditions like speed,...

What everyone said is that the max inflation pressure is 80psi and that inflation is done cold. So you would go to whatever pressure above 80psi the tire temperature dictated after...
