Uhhh, see this: a nitrogen molecule measures roughly 300 picometers while an oxygen molecule measures 292 picometers. That’s only a 2.6% difference in size. One picometer is equal to one trillionth of a meter (1 m / 1,000,000,000,000). The Nitrogen molecule is slightly bigger so therefore the marketing is that Nitrogen will not permeate the tire walls....Physics is there, common sense is not. Put good ole air in their. Air is 78 percent N anyway.
