2 Separate Blowouts on RV Yesterday. Learned Important Lesson on Tires

"Tires need to run."

Supposedly tires literally need exercise, but sitting around, they deteriorate much quicker. As the story goes, the constant flexing of the material keeps the oils activated throughout the tire and it lasts longer.

I'm no tire expert, but that's the way I heard it, and I'm sticking to it.

so here is a thought, on my wifes car i got 2 sets of rims...winter and summer tires
about 4 month out of the year the winter tires are on the car, and the other 8 they are sitting under the lean too, or in the shed, depending on where i am when i switch em

do you think them sitting for that long would be bad for them too, or are we talking longer term then that?
