Nitrogen Fill
A Smart Choice for your tires


Get a nitrogen fill at Henna for $39.95 and if you replace a tire or have a flat, we will fill up your replacement tire for free!

How Nitrogen works and what it does

Nitrogen (N2) makes up the majority of the air that we breathe and is contained in the protein of all life on earth. It is colorless, tasteless, and non-toxic. The next most common component of air is oxygen (O2). Together N2 and O2 make up approximately 99% of the air we breathe and traditionally fill tires with.

N2 is a larger molecule that O2.

Therefore, it cannot escape as easily as oxygen through porous material such as a rubber tire wall (carcass). Leaking at a much slower rate than oxygen, a tire filled with a higher percentage on N2 maintains its proper pressure roughly three to four times longer than air-filled tires. Proper inflation provides better fuel economy, superior handling, longer tire life, and increased safety by reducing the like hood of low pressure related loss of control, blowouts and other tire failures.

N2 is a dry, inert gas.

O2 in a tire provides unwanted oxidation. Over time, this reaction destroys the tire carcass and corrodes wheels. A tire is prematurely aged by O2 from the inside-out as the pressurized air in the tire makes the O2 try to escape through the tire carcass, speeding up the damaging oxidation process. N2 on the other hand, is a harmless inert gas that does not react negatively with tires and wheels. N2 filled tires also reduce tire hear, thereby decreasing rolling resistance and increasing fuel economy.

N2 is non-flammable

O2 is a flammable gas while N2 is an extinguishing gas, Thus, a large number of mass transportation companies around the world fill their tires with N2 for added fire and explosion safety. In a vehicle fire, ruptured air-filled tires fuel the fire. N2 filled tires slow the fire.

N2 has been used in tires for many years on aircraft, military vehicles, off road trucks, racecars and even Tour de France bicycles.

Nitrogen inflated tires are safer and longer lasting than tires inflated with air

  • Nitrogen inflated tires do not age as quickly as air inflated tires
  • Nitrogen inflated tires minimize blowouts
  • Nitrogen inflated tires improves vehicle handling through proper inflation and consistently maintained pressure
  • Nitrogen is an inert, non-combustible and non-flammable gas
  • Nitrogen is a stable gas providing more constant pressure
  • Nitrogen is a dry with no corrosive properties as found in compressed air

Correct inflation versus under-inflation

Correct inflation is highly significant when considering tire life and performance. It is not always possible to look at a tire and detect under-inflation. However, under-inflation can cause many tire-related problems. As inflation pressure largely determines a tire's load capacity, under-inflation results in an overloaded tire. An under-inflated tire operates at high deflection resulting in decreased fuel economy, sluggish handling and may result in excessive mechanical flexing and heat build up, leading to catastrophic tire failure.
