Took the time on Saturday to check the air pressure on the XFire and my other vehicles. As expected, all were low; some considerably low. Fired up the compressor and corrected all the tires. Went to within a couple of pounds on all tires, as it is expected to return to the mid-to-upper 50s late next week. All the tires should be okay then. This is routine maintenance I perform every 45 days on all my vehicles.
