Except that no one has been able to find a correlation to tire failures.
Plus, oxygen will find its way INTO the air chamber, even if the air chamber starts with 100% nitrogen. The process is called the "Partial Pressure of Gases" - which states that you can treat a mixture of gases but looking at each independently. That means the oxygen in the atmosphere will leak into the air chamber.
The conclusion within the tire engineering community is that the use of nitrogen as an inflation medium doesn't appreciably change the oxygenation effect and can be ignored.
