Not significant. There would be negligible advantages of N2 more or less of an academic value. 1) Les weight 2) Les pressure loss by membrane diffusion 3) Less corrosion 4) More fire safety All the benefits due to absence of oxygen - and repeating again: would be hard to prove it practice.

@@curiouscat8457 its a scam mate, my neighbor got nitrogen filled tyres and they charged him 5 dollars per tyre... they even did the spare. What id like to know is if pure nitrogen is so great then what process do they use to get all the old air out of the tyre? Truth is they can't... so instead of having a mix of 80% nitrogen and 20% oxygen you'll probably end up with 95% nitrogen and 5% oxygen... and for 5 dollars a tyre??? Ill stick to air and save my money, especially when in 3 months times i top the air up at a gas station and dilute the mixture even more... an absolute scam.

@@tims001 Absolutely. I didn't say it as directly as you have, but you can read it between the lines :-).

It will prevent dry rot

@@crpro5420 The outside of the tyre walls are subject to a far more hazardous environment (wet, frost, snow, road salt, UV) and they seem to do OK....

And NASCAR

nice

Upside down ...you know what it means
