Why use nitrogen for the tire

[Saaber]

Why inert tire gas filling?

 

Formula 1, aviation and hazardous transport trucks use already for a long time inert fillings of tires. Most of civil drivers do not take care on their tire pressure. Because the pressure loss is reduced and the fire risk is avoided this filling of tires contributes substantially to security, comfort and economy .

 

What is an inert filling of tires with nitrogen?

 

The compressed air normally existing in the tire is replaced by an inert filling with tire gas. This gas is cleaned from particles, oil vapour and humidity. Above all especially this air is oxygen-poor, i.e. inert (= low reactive).

 

What causes inert filling of tires?

 

Inert tire gas avoids oxidation at the rim and valve seat. Also the tire rubber is protected inside against oxidation by the low oxygen share. Inflammations in the tire inside are not possible any longer, since without oxygen in air no process of combustion can take place. The loss of the molecules by the rubber wall of the tire (pressure loss by diffusion) is reduced.

 

 

What are the advantages of a more constant tire pressure ?

• More driving safety by better handling characteristics
• Higher durability of tire caused by optimized rolling resistance
• More comfort by better taking up of impacts
• Less fuel consumption caused by lower rolling resistance
• Better handling & road holding
• Reduces tread wear and increases tyre life by up to 25%
• Correct inflation pressures reduce puncture risk by up to 33%
• Reduced rolling resistance improves miles per gallon by 2%
• Improved pressure retention
