I have 6 motorized vehicles and 4 trailers. I live at 4200 ft and drive to 6200ft regularly. Years ago I figured out that the door post pressure on the vehicles would lead to edge wear on the tires at this altitude. The pressure on the sticker was based on sea level. I add 5 lbs to each door post pressure and have had even wearing tires for the last 10 years. I do the same for the trailer tires. 5 over the max on the sidewall and I have never had center tread wear before the side tread. Your experience may be different but that is my experience.
