Tires on a PopUp.

Hello All! How long is to long for tires to sit without being move?Does dry rot come from not being moved and how long? My Popup has not been moved in about 8 months is this not good for the tires?This might sound like a dum question but i don't know. :) :blush: Thanks
Tires on a PopUp.

Keep the tires inflated, put your leveling jacks under the camper and take some of the weight off the tires, and keep a layer of armor-all or some kind of protectant on them. It wouldn't even hurt to cover them to keep the sunlight off them. Don't forget a little armor-all on the valve stems too.
Have a good day,
