Firstly do tire covers help, not much or a lot? What should I look for when buying tire covers? Any recommendations on which ones to buy or stay away from? Thanks, Phil
Way2roll has already mentioned that a major factor is using the tires. Tires age quickly if not run frequently. I gave up worrying about sunlight after I tried to put my 4 year old spare tire into rotation. It seemed ok until it was on the truck for a week or two and the cracks appeared virtually overnight. That tire had been under the truck bed and of course never saw direct sunlight or excessive heat.
