I was curious how much ititial cold tire presure folks run on their Ford F53, 19.5 tires. I run 85psi cold all way around. I understand loading ect.
I have noticed that pressure will rise approx 10psi while driving on a warm day.
Thanks.
One need only concern themselves with cold tire pressures, no matter what the ambient might be for that particular day.
Each axle must be weighed and I always allow 10 - 15 psi for a cushion and to take care of all the variables that can and do take place over an extended trip, especially. These would include changes in ambient temps. as well.
