MARATHONS/TPMS
The problems with GY Marathons may be an unrealistic pressure gain. Purchase a TPMS for Christmas for our Monty. On our spring trip to Gulf coast, left home tire pressure set at 80#, as we traveled(about 120 miles)air temp about 72, Tire temps were running 90+. Tire pressures went to 95+, setting off alarm on TPMS. TV tires gain average 6#. Lowered tire pressure continued on trip. After a couple days, checked tire pressures cold, 75# average. On return trip air temps in mid 80's, tire temps 90-95, pressure 85-90. G614's before fall trip. Highly recommend TPMS for all Monty owners, or for any rver out there.
