Thanks for the professional information wmtire. Reading your post regarding over inflation calls to mind my experiences traveling from Western MA to TN at the end of December (two years in a row). We left our home with both tires inflated to 50 psi as recommended by the TM manual. Arrived in eastern TN the next day and spent the night. Checked the air pressure before leaving (the next morning) and discovered the pressure was 56 psi . . . and that was a cold reading. I think elevation and ambient temperature may also play a role in pressure variations.
