 | Pressure Two of the main gases found in air, oxygen and carbon dioxide, contain very small molecules. Over time these molecules permeate the rubber tyre which reduces the pressure in the tyre. Pure nitrogen molecules are larger than those found in oxygen and carbon dioxide and cannot permeate the rubber. This keeps the tyre pressure constant for a mucher longer period and ensures the correct amount of tyre is in contact with the road. |
 | Pressure When the temperature of rubber in a tyre increases the water vapour found within the air inside the tyre reacts and causes the tyre to expand. Temperature change has little or no effect on pure nitrogen molecules as it contains no water vapour. This keeps the tyre pressure constant when in motion and ensures the correct amount of tyre is in contact with the road. |
 | Pressure Normal air within tyres contains water vapour. Over time this can cause the inner wheel rim to rust. Nitrogen contains no water vapour and prevents this rust build up. This keeps your car in best possible condition at all times. |
- Extended tyre life
- Reduced fuel consumption
- Increased safety
- Higher performance
Tests have shown that the average car driver could save between 4% & 7% in fuel bills when inflating with nitrogen instead of air. For example, an average domestic vehicle doing around 30mpg, covering 12,000 miles a year, would save around £100 annually on fuel. Tests also prove that the average life of a nitrogen-inflated tyre is 20% to 30% longer, saving a driver doing 12,000 miles a year £30-50 on replacement tyres. Join our Nitrogen club today!
