Gladly. The differences in pressure are based on the average bicycle bearing 60% of the weight on the rear tire. This is why rear tires wear faster and rear wheels are often built stronger. The extra weight means the tire needs to be run at a higher pressure. In the spreadsheet you can change the percentages, but 60/40 is pretty accurate.
As long as there is not an ozone source in the closet (usually generated from electric motors like in a refrigerator) the tire in the closet should last a long time. When you are ready to mount it, look it over carefully for cracks. Fine surface cracks are not a problem, but large ones going through the rubber and to the casing are a concern. If you wanted to put it in a plastic bag, like a trash bag, that might protect it even more. That's probably not necessary though. It doesn't hurt to have a spare on hand.
