My "design" pressure on the tires us 120 psi cold. That's what I keep them at here in Florida. Just got back from five weeks on the road with some temps around 40F that brought the pressure down to about 105-110 psi just due to temp. I did basically what clr indicated from that manual with a low around 100 (about 15% below norm) and a high around 130 (about 10% over). On the temps, I just left the defaults in. I can tell you that today with air temps of 89F and five hours of driving at 65 mph, my tire temps were around 90. Also, I had been losing signal from the sensors on the toad, so I added the repeater this trip and it worked great. No signal loss at all. Rather than install it where it could possibly drain a battery, I bought a 110V to 12V converter for LED lights and mounted everything in the cabinet behind the bedroom TV and plugged it in there. The inverter keeps it powered while driving, so no battery drain. I think the converter was $10 on Amazon and connected straight to the repeater.
