The only vehicle I have that actually "wears out" its tires is my motorcycle, since I drive it 80%-90% of the time. I also have a car in nice condition for nice events, and my ol' Cummins diesel Ford F-250. What can I do to keep the tires on the vehicles from dying due to age? I never wear them out (going bald)... they just get "old". Armor All is worthless. It just destroys the rubber, turning it into goo. I have also tried covering them to keep them out of the sun, but that does not help much, either. (Due to ozone in the air??) and the covers don't like to stay on, and also deteriorate (and are not cheap). Any other options? If things go really bad, I think finding good tires that don't cost $1000 each will be a challenge.
