I have always run 50psi front and back when using as my daily driver and then airing up to 80 when I load the camper. I had to have the TPMS system reset in my current ride to allow 50PSI as it was set at 70PSI and I hate looking at the light in the dash. I just replaced the factory Bridgestones at a little over 45,000 miles and they were wearing very evenly. In fact they could have gone another 10,000, but I run many miles very rough dirt road every month both loaded and unloaded and hate changing flats so replaced them before camping season.
