N2 = nitrogen; I have done few researches on its advantages over air and found out the following:
1. N2 help regulate internal temp more constant, hence your tire pressure will remain fixed even in variable condition.
2. No water beading. As the internal temp remains constant there is no chance of H2O accumulation thus preventing corrosion.
3. Tire should perform better as the psi remains constant and study even say that tire also last longer.
TAI member can contribute more points on it.
I have Turtle Wax - bought from ebay (looking original to me) and was thinking to try it. wax is a coating which protects the cars paint so theoretically i should apply wax to protect the paint and shine.
