Nitrogen in tires

Nitrogen in tires is becoming a popular replacement for standard air. Nitrogen is all around us... the air we breathe is 78% nitrogen, 21% oxygen and the rest is small amounts of other gasses. When it comes to tire inflation, nitrogen has many advantages over oxygen. With nitrogen tire inflation, improvements can be noted in a vehicle's handling, fuel efficiency and tire life through better tire pressure retention, improved fuel economy and cooler running tire temperatures.

A colorless, odorless, and tasteless gas , nitrogen could cost you as much as $10 a tire.

Most expensive air filled in my m3 tires..

I paid 40 dollars plus tax at the Fairfax BMW Service..

do any of you have one?
