Don't know if this will help or not, but here is a product that I used called Smartire. The sensors mounted to the wheel and sent information to a display I had on the console. It gave tire pressure and temperature information. There were pros and cons to the system. IIRC, I ran 285 BFGMT’s then at 60 psi. In the cold the tires would start off at approx. 53-54 psi, then increase in pressure as they warmed up.

Edit to replace picture.
That looks pretty sweet! I imagine changing the batts would be a 'con'. Any others you remember?
