Re: Nitrogen in Tyres

That research is specific to TRUCK tires, not performance
rated tires on sporty cars used at Driver's Ed. The reason
for using nitrogen in these TRUCK tires is to minimize
deterioration of the tire carcass over long periods. I
don't doubt that this is valid.
However, this would only be applicable here for those folks
who keep the same set of tires mounted for more than a couple
of years.
One driver's school will probably scrub off at least 10% of
the tread rubber on a set of tires. Anyone doing drivers
schools should probably invest their efforts elsewhere since
their tires will be shot within two years anyway. IMHO, of
course...

The _ONLY_ reason to use pure nitrogen in your tires at Driver's
Ed. is to eliminate MOISTURE. Any moisture in your tires will
increase the pressure rise due to temperature at a much greater
rate than the main components in "air". Since you don't know
exactly how much moisture is in there and it is not terribly
repeatable, predicting pressure rise with temperature is
difficult.
Actually, normal compressed air, if properly dried, will give
as much benefit as pure nitrogen.
I would hazard a guess that anyone querying about Driver's
Ed preparation is enough of a novice that he/she will have
much more important things to worry about than a couple of
pounds variability in hot tire pressures...
Just find an experienced driver in the morning with a car
kinda' sorta' like yours and ask them what they'd recommend
for starting pressures. Put that in and then focus on your
driving and having fun.
