Smarti has it right. However, you need to adjust your cold pressure with seasonal changes in temperature. I run 42 psi cold. Forget what it does as the tires warm. Nitrogen is pretty much a scam in car tires. It's used in high performance aircraft to prevent a fire if a tire blows. The Concorde's tires were filled with nitrogen. I currently am running General Altimax RT-43's and they lose literally no pressure. Some tires lose more, some less, through the rubber. I don't depend on the DIC for setting pressure. My favorite gauge now is a CyclePump inline analog gauge. (www.cyclepump.com). You attach it to the valve stem, then fill thru a fitting on the gauge. There's also a buttom to release air. Very convenient as you can observe the pressure while filling. I won it at a motorcycle rally.
42 psi, Goodyear OEM Tires
I run 42 psi in the Goodyear OEM tires. Gauged when cold. It is so hot in this area, ambient temps 108/111 degrees fahrenheit, that the DIC tells me the pressures are 46/49 psi after 10 miles of 65 mph freeway driving. When cold the DIC reading is fairly accurate when checked against an electronic pressure gauge.
What pressure would you run in these conditions when checked with the tires at 72 degrees?
