The rubber compound characteristics for heat up time & hardness vs softness is what makes the difference for all cars, the air or nitrogen/ gas used will NOT make one tire better then the other simple because its filled with it , Air is 79% nitrogen, 20% oxygen, and 1% other gases ,
a Marketing ploy by the service stations is all I see with nitrogen fill stations as all fill stations are 79% nitrogen already..
