Hi Ross,

For grins, the ideal formula is P1T2=P2T1, temperatures in kelvin.

For example:

In the morning when it's 80 deg F (300 deg K) you set your 315 pressures to 130 psi and you get on the road, the day warms to 100 deg F (310 deg K) and the work done by the tire warms the tire an additional 50 deg, so your tires are now at 150 deg F ( 340 deg K).

Solving for P2 your runtime hot 315 tire pressure will be (340/300)*130 = 147 psi,

and with the 365's the runtime hot pressure is (340/300)*110 = 125 psi

Add in some sun baking, stops and brake heat, turns and hub bearing friction and we're pretty close to what you are seeing. Looks normal.
