We can now offer nitrogen tyre filling at RoTechniks.
Sussex Police force, in the United Kingdom, carried out a roadside survey to check tyre pressures due to their concern with incorrectly inflated tyres. The check allowed a +/- 5psi tolerance against recommended handbook pressures.
The results of the survey were that 73% of all cars checked had incorrect pressures
Police also check the tyre pressures of every car involved in a road traffic accident in the UK. This data shows that 86% of vehicles involved in road traffic accidents have incorrect tyre pressures.
Tyres that are under inflated by just 20% (4-6 psi) on average can add £2,600 to a fleet tyre bill that should be £10,000, a 26% increase in cost. According to police figures 73% of tyres checked were 5 psi out against handbook pressures
It is estimated that under-inflation of 20% can cause fuel costs to rise by 5%.
Compressed air contains Water, Water vapour and Oxygen, which attacks the wheel rims and shortens the useful life of the rubber.
Certain components namely Oxygen, water vapour and free water that are found in compressed air are prone to permeation through the tyre structure. This is not from faulty valves or leaky rims but a natural pressure loss across the tyre and into the atmosphere. Of these components, both water vapour and free water can enter the tyre in varying amounts even if identical tyres are inflated with the same gauge on the same day. Compressed air is not a specified gas and as such will always contain varying amounts of these components that are not suitable for tyre inflation.
Under inflated tyres create drag which increases tread wear, fuel costs and the risk of punctures as well as having a significant effect on a cars performance both in handling and cost. Nitrogen filling produces a stable inflation mixture, as can be seen in the diagram on the left, that has improved pressure retention properties that will ensure tyres remain fully inflated for longer. By having your tyres at the correct pressures you will experience the following benefits:
1. Better handling and road holding
2. Reduces tread wear and increases tyre life by up to 25%
3. Correct inflation pressures reduce puncture risk by up to 33%
4. Reduced rolling resistance improves miles per gallon by 2%
5. Improved pressure retention
Tyres inflated with Nitrogen ran 26% more miles before having to be replaced.Tyres Inflated with Nitrogen gave 48% more miles before failing.Tyres Inflated with Nitrogen had a smaller failure percentage than compressed air, 30 % compared to 57%.Nitrogen is used in all Aircraft tyres for safety due to the explosion risk caused by oxygenNitrogen is used in earth moving vehicles due to the risk of latent heat explosion.Uniflate Nitrogen has been the sole inflation medium for all Formula 1 tyres for over a decade.
Under inflation and over loading causes heat build up leading to heat related damage and failure.Under inflation reduce tyre life and increase fuel consumption due to increased drag.Incorrect tyre pressures cause vehicle handling and road holding to be affected. Our machine also is calibrated every 6 months to ensure accuracy.
