Nitrogen Tires

Actually, we won the CASC GTA championship this year, so we must be doing
something right.

Yes Yes & Yes
But the cost & effort seem hardly worth the effort.

In fact it is true that nitrogen is better than air. However, this is
generally used for fleet operations. The benefits for a passenger car would
be minimal. Nitrogen is a "larger" molecule than the oxygen in the air. As
a result, the tires will hold their pressure over a longer period of time
resulting in less maintenance time to check the tire pressures. This leads
to better mileage and better tire tread life with less maintenance effort.
The maintenance effort can become very important if you're managing a fleet
of vehicles. For a passenger car, just check your pressure regularly and
you'll get the same benefits.

 

Interesting, N2 has a molecular weight of 28.02 g/mol while O2 has a
molecular weight of 32 g/mol. Is there something I'm missing here?

 

The Mol Wt is not necessarily an indicator of the size of the molecule.
