I have one example. I recently purchased these 17" 2006 Camry SE wheels and tires for my parents 03' Sienna because I wanted something nicer than the stock 15" alloys which were clear coat chipping and looked horrible. To my amazement, this guy had this original set of wheels and tires with probably less than 5000 miles that were taken off sometime in 2007 and immediately wrapped up in these thick old school Discount tire plastic bags and put in the garage. FYI, the newer bags they give you now are about 3x thinner, probably as a cost cutting measure.

When I opened these bags up, I got the smells of brand new tires and a richness of rubber filled the garage, like I was in a tire shop with hundreds if fresh tires on the rack.

These tires not only had been preserved in these bags, but there was no signs of dryrot anywhere on the tire tread, doors or sidewalls. The tread blocks are still plenty pliable and the rubber is still elastic.

So what I would do is find some thick plastic bags and tie those shocks up tight in there to keep them as fresh as possible.
