Why do nitrogen filled in modern vehicle tyres, Does filling nitrogen in tire have any benefit ?

Normal air contains about 73 % of nitrogen and rest contains 20% of oxygen and other vapor. Filling nitrogen instead of air is generally in racing cars tyres, aircraft tires and in heavy commercial vehicles. In normal air filled tyres commonly heats when running due to the moisture inside the tire. If we filled nitrogen in tires the running temperature reduces dramatically and the result is longer tyre life. In case of tubeless tires nitrogen doesn't reacts with rims. We do not need to check tyre pressure regularly if filled the tire with nitrogen ( check it after 5 months).

Some major benefits of filling nitrogen in tires are


  • Low inflation pressure loss.
  • low wheel corrosion.
  • Nitrogen prevents inner rubber deterioration by oxidation
  • Tires run cooler.
  • Increased tread life.
  • Increased mileage.
  • Helps prevent uneven wear.
