Theoretically, nitrogen has less mass as compared to air molecules so nitrogen has more velocity than air and nitrogen will exert more pressure on walls of tube present in tyres, therefore, the risk of damage of tyres during the summer season will be more when nitrogen is filled as compared to air. But most of the people recommend nitrogen for tyres than air and I too felt this is true because the tyres filled with air is so hot when we go for a long ride as compared to tyres filled with nitrogen. Why does this happen?
