In this modern age where many cars are fitted with air conditioning systems as standard equipment, and therefore fitted with a dual layer system, it is also vital that the car owner has at least one set of spare tires on the vehicle. Depending on how many layers are present on the auto tires, one may find that they have to change their wheels more often. There are many reasons why the tires need to be changed, including poor performance, worn out tread areas and even the dreaded co2 emissions.
The number of layers in non-pneumatic tires gives an idea of their rolling resistance. Tires with fewer layers provide less rolling resistance than those with more layers. Thus one can conclude that having fewer layers will give better grip on wet or slushy conditions, while having more layers would give better resistance in other conditions. This may make airless tires preferable for those driving in wetter climates or in climates where the temperature often drops below freezing, since in these cases having additional layers of non-pneumatic tires may be beneficial.
It may be assumed that airless tires are without problems when it comes to temperature, however they are not all. There are two other factors to consider when debating the benefits versus disadvantages of having airless tires fitted to a vehicle. The first of these factors pertains to the level of fuel consumption of the car, as airless tires require a lesser amount of fuel to function properly. However it should be noted that although they consume less fuel, their engines are not idle during the drive or when switched off, so the amount of fuel consumed is dependent upon the regular use of the vehicle.
Another point of debate relates to the varying styles of automobile tyres available. Airless tires are made from rubber compounds, which in themselves come in a wide variety of compositions. Some examples of such compounds include EPDM (ethylene propylene diene monomer), polyurethane (polyethylene propylene diene terpolymer), and polyacrylic. Depending on the actual driving conditions in the area where one resides, certain compounds will prove to be better than others. In certain locales the temperature can vary on a seasonal basis; in these instances certain types of airless tires may prove to be unsuitable.
As an example of the variation of performance between various tire compounds is found with respect to tread depth. A typical airless tire of an ABS built vehicle will have a tread depth of six inches, whereas that of a standard tire may only measure four inches. This difference in thickness of the tread can, as a general rule, only be accounted for by comparing the individual characteristics of the two types of tires. Some drivers, for example, prefer a narrower profile that does not sacrifice protection on either front or rear wheels. However, the ABS built airless tires will allow a tire profile that sacrifices protection on either side.
Airless tires are also available in a specialized form that is better suited for wet and winter road conditions. These types of trucks tires are commonly referred to as mud tires. While their primary function is clearly to provide traction in a variety of circumstances, they can be used on paved surfaces in addition to gravel. They work well in this situation because their width is greater than that of most other types of tires. This allows them to better grip the snow and ice and therefore prevent slippage.
Another way that airless tires perform better than their non-pneumatic counterparts is that they have a much lower level of internal friction. Because there is no seal between the tire and the wheel, there is a reduced amount of friction. This, in turn, lowers the overall tire rolling resistance. The lower rolling resistance in turn increases the fuel economy of the vehicle. However, the fuel that is saved can be offset by increased insurance premiums.
In most cases, choosing a more expensive non-pneumatic tire would be the best option. Unfortunately, purchasing non-pneumatic tires for all types of driving conditions would be extremely costly. The higher the level of care that is needed with these types of tires, the more expensive the tire would be. On the other hand, an airless tire is much less expensive to replace in the event that it is damaged or needs to be repaired. Therefore, purchasing airless tires for the most common types of driving would be the most economically sound decision.
