I always joke about “winter air” and summer air. In the tires of course. Just like your car tires get low in the winter due to the cold, the motorhome’s huge tires get “WAY LOW.” Like from 95psi to 75 psi! So when it’s time for a winter trip, it’s time to put some “winter air” in the tires, pump them all back up to 120 front, 95 rear. While I’m at it, since I have to unscrew all the TPMS Sensors anyway, I check the battery voltage, and change the batteries if they are low. This time, they were all a bit low, 2 were completely dead. I changed all the sensor batteries and filled all the tires. 1-1-23 Jim
