I'm running 265/70/17 big horns on the XK pretty aggressive tread. My question is on the amount of tire pressure I should be running at. They were installed with about 37PSI but the tire says 60PSI. I know what pressure to run for sand and off roading mud and rocks. But what are you guys running on the street with these type tires. I know more PSI better gas mileage I think but would like some feed back on what you guys are doing. 60PSI just seems Like a lot to me any feedback would be great thanks.
