Economical driving, how to do it?
You like long and dynamic car trips, but you think you have to visit a gas station too often? If you want to reduce these costs, pay attention to the wheels of your car.
The vehicle in motion has to overcome a lot of resistance, and the necessary energy is taken from the engine, of course. One of the simpler and cheaper ways to reduce fuel consumption is to reduce the rolling resistance caused by the wheels. Rolling resistance cannot be fully eliminated, and this phenomenon also has its positive aspects in the form of wheel adhesion to the ground. The easiest way to illustrate this is to drive on an icy road. Rolling resistance in this case is very low, but there is also low grip, which makes it difficult for us to move forward. In practice, however, we are more likely to encounter rolling resistance, which is much greater than is advisable. This is always the case when the tyre pressure is too low.
Take care of your tyre pressure
We can fight rolling resistance in several ways. The easiest way to do this is to ensure optimal tyre pressure. This will not only reduce these resistances, but also ensure safer driving and a longer service life for the tyres themselves.
The fight against the phenomenon of excessive rolling resistance was undertaken by tyre companies offering us ‘energy-saving tyres’. The design of these tires and the rubber compound used in them are designed to reduce the weight of the tires and reduce their deformation during driving at low pressure, among other things.
Green tyres can save around 3-6% on fuel costs. In terms of cost per driver, this figure does not seem to be high, but if we take into account the overall reduction in consumption by all drivers living in a medium-sized city, such a decrease in demand can already be seen by Sheikhs on the Arabian peninsula. If we do not want to annoy the oil companies or the environment, but only our own savings on the running costs of a car, the supply of energy-efficient tyres will make little difference. What we save on fuel costs will mainly cover the cost of buying more expensive tyres in this segment. This raises the question of whether there are better ways to use a car more cheaply.
Nitrogen in a tyre
Frequent checking of wheel inflation can be tedious because it involves visits to a vulcanisation plant or having your own wheel pressure gauge. The best way to maintain optimal tyre pressure is to try to eliminate the causes of tyre leakage. The most important of these are a leaking valve in the rim and the penetration of oxygen particles through the butyl layer of the tyre. As for the valve, remember to replace it with a new one every time a tyre liner is fitted on a rim. However, the second cause can be dealt with by using the service of inflating the wheels with nitrogen instead of traditional air. Why is nitrogen a better solution? This gas shows half the tendency to penetrate the tyre’s layers. It also does not change its volume in response to changes in the outside temperature and the temperature associated with heating the tyres while driving. The cost per tyre is relatively low, usually US$5. At this price, we are guaranteed to maintain the correct pressure three times longer and there is no need to control it, especially when our car is not yet equipped with TPMS system. It is worth going to the point which has a generator in its equipment, because thanks to this device the concentration of nitrogen is obtained at the level of 98-99%, while the one from the cylinder does not usually exceed 94%.
