Hello,
I say (actually, I SHOUT) BULL****
Let us say it was even remotely true...
I fill my tires with 'air', ie: 80% nitrogen, 20% o2...
After 2 month, the o2 went away and I lost 20% of my tire pressure (which with
30 PSI would bring me down to 24PSI, really close to the recomanded 26~28 PSI
for the car anyway...
I refill the missing 20% with 'air', I now have 96% Nitrogen and 4% o2, which,
even if it went away would only bring my tire pressure to 28.8PSI, largely
within the tolerances for the crappy pressure gages that we are using, or the
normal cold/hot changes..
But let us say, I refilled a 1/3 time, I now have 99.2% Nitrogen in my tires
and .08% o2... not really a problem, and it did not cost me $8!
