check psi in the morning before the sun warms up the tire and of course before you run the tires. If the sun warms a tire 10F higher, the PSI will rise 1 PSI.
I run a 65psi 'D' tire on the OEM wheel that had 'C' tires (i dont know the psi rating of the wheel) I run them at 65psi as well as 60 psi and i dont notice any difference in feel.
I have checked the temps from time to time using a digital tire thermometer and didn't really notice much difference in tire temp. between running them at 60 or 65psi.
(Maybe the load on my tires is not near max).
Prior to buying new D tires, i ran the C tires at 50psi and at 45psi , again no difference in temp that would blow up the tire.
Again, my tires are under the load capacity , maybe if i was running at max capacity it would make more of a difference.
