Got them out of storage today. They should be ok right since they have been sitting on a shelf in my garage since April of this year. I got them last November because my stock all seasons were crappy in the snow previous years. They're Blizzaks if it makes a difference. Is there any prep work I have to do to them before having them mounted in a couple of months?

 

I ran a set of tires/wheels that had sat untouched for 4 years, still had air in them. Unless they are dry rotting they should be fine, no prep needed.
