The 5 gallon buckets for paint make pretty good storage containers for tires. Be sure to use the ones with the O-ring sealed lid. Keeping air & sunlight away from the rubber does a lot for longevity. One front & one rear tire per bucket…
You don’t need to do anything to store a tire but here’s what I do. Take the tires off the wheels, turn them around and put them back on the wheels, then put them back on the kart on the opposite sides. Get a heat gun and a scraper and clean the clag off then wash with trac tac blue tire wash after it’s dry wrap in cling wrap then shrink the wrap with the heat gun. next year take the plastic off and brush on one coat of trac tac SST a week before the track. Then the day of the race I throw the tires away and mount a new set.
