I made a pressure/temperature calculator for wet and dry. 
If you would use that, you see that the pressure rising represents a higher temperature in tire. 
I did not use it now, but your pressure rising look like no extreme temperature in tire. 

Will give a list for cold filled pressure at 70 degr F, and the degrF change per 1 psi change. 
Then you can calculate by head, while dtiving even, the new temperatures in tire. 
Pretty normal for average driving is 120 degr F of gascompund in tire. 

But if you want to play with my calculator, mail me at hotmail. com adress with username jadatis. 
Combine yourselfes, spamm-machines cant this way.
