[TR] Nitrogen in Tires

[mark.jones at exxonmobil.com]

Personally I can't see the point to it.  Air is already approx 78% nitrogen
(and 21% oxygen) and the nitrogen molecule is just a bit bigger than an
oxygen molecule.  So, to me, putting pure nitrogen into a tire , as opposed
to plain old air, will have no affect on how fast a tire looses air
pressure.

I just had my new tires installed on the TR6 and the tire shop is now
offering nitrogen as an "air" option. This shop was also featured in the
local newspaper with a big article about the benefits of using nitrogen. I
wasn't willing to spend the $50 which came down to $25 by the end of the
installation but wonder if anyone, other than racers, use nitrogen and
notice a difference. I know that racers use it to maintain a constant air
pressure regardless of heat but how about for everyday use? Is it worth it?
