I NEVER let a dealer touch my tires. I always show up with my Guage post service to check. Seems all techs are clueless about tire pressures.
Will not cause alignment issues. If tire mileage is important to you, rotate. If fresh rubber every 2-3 years is more important, just run them till done or as i do with snow tire season, rotate in spring annually. Really depends on driving style. If you grind around corners locally, you will wear outside front edges more dramatically. Highway drivers will wear the rears quicker across the tread.
