Compressed air is your tire’s worst enemy. Air is about *8% nitrogen, *1% oxygen, and 1% other. Nitrogen is inert, non combustible and non corrosive. Oxygen, on the other hand, is immensely destructive to rubber and other tire materials. As soon as a tire is manufactured and exposed to air, the effects of “oxidation” begin to deteriorate the rubber. Over time it loses its elasticity and strength, just like an old rubber band you’ve probably found around your home. This same process occurs in tires inflated with air as the oxygen attacks the rubber molecules, working from the inside out, until the oxygen, and its destructive properties, permeates the tire structure and ultimately the tread.
