Tyres and the fuel economy

Is there a change in fuel consumption after changing your tyres? If yes, than congratulations because you are about to unlock the secret to save some extra bucks, so stay tuned and keep reading.

Question: The multimillion-dollar question is, how does a tyre affect the fuel economy?

Answer:  About 20 percent of the vehicle’s fuel consumption depends upon rolling friction. It influences fuel economy consequently influencing the operational expenses and carbon dioxide emissions of the vehicle. The lower the rolling friction is, the lower the fuel consumption and carbon dioxide emission will be.

With regard to mileage or fuel economy its all about rolling resistance. The laws of material science states that stationary objects like to stay as such, so moving those items requests energy. In terms of an automobile, the energy is generated via fuel. The more rolling resistance your vehicle faces, the more fuel it will consume.

Following is the table showing the fuel consumption areas for city driving:

Previously, purchasers frequently settled for an exchange off between low rolling resistance and other specification of tyre, for example, wet braking & tread life or even price. At times, consumers simply compared Yokohama Tyres price with those of Dunlop or between other brands, and selected the cheaper option. Yet, as of late, tire producers have been manufacturing the superior tyres by incorporating all season grip & low rolling resistance within a single tyre.

Here is a guide to economical tyres so you can decrease the fuel consumption of your vehicle:

Ways to increase fuel economy in terms of tyres

Tyre pressure

If your tyres are under-inflated by 8 PSI the result could be increased in the rolling friction for about 20%. Be sure to check your tires for tyre pressure on a month-to-month premise. When you fill your tires follow the owner’s manual for optimum performance and better fuel economy.

Another study of the U.S Department of energy suggested that loss of .3 percent of the mileage is a result of every one PSI drop of tire pressure.

If the tyre pressure is well maintained not only the fuel economy will increase but the life of a tyre will also increase.

Tread design

Mileage is inversely proportional to the deepness of tread on the tyre. Tread design enables your tires to get through the nasty climate and when you need to brake all of a sudden.

As a tyre tread wears out its fuel efficiency increments. Fresh out of the plastic new tires will have a new and deeper grove resulting in high levels of rolling resistance. As the tyre is used, the tread groove depth lessens. Because of worn out tread and decreased mass of rubber the energy required by the vehicle to overcome the rolling friction is less hence having the improved fuel consumption.

Race vehicle drivers utilize tyres with lesser tread design and shallow groove since the absence of tread improves mileage and increases speed. But in terms of the everyday driving tread is important.

In case you are driving on a rough terrain that is thick and bumpy, the deeper tread will help you to tear through the fudgiest mud, however, it will debase your fuel efficiency altogether.

Size of the tyre

Littler tires on a littler wheel are simpler to get going from those numerous stops we make driving in the city. This is on the grounds that the Littler tires causes less contact or moving opposition than a heavier, bigger wheel.

Bigger tyres are better for high-speed driving since littler tyres put more work on your motor, increasing the rate of rotation per minute (RPM).

A few drivers need to change the size of the tires they put on their vehicle, however, the best tires for ideal fuel mileage are the stock tires suggested by the vehicle maker in your proprietor’s manual.

Tyre type

Always know the type of tyre your vehicle is compatible with. In case you install incompatible tyre your vehicle will have high fuel consumption and lower tyre life, plus you will not be able to experience the optimum driving.

You should always keep in mind the load rating of your vehicle and whether you are conveying loads according to the prescription of the manufacture since wheels have an assigned burden limit. If you overload your vehicle it will not only consume more fuel but it can also be extremely dangerous.

Consider the size of the tire which specification match to the wheel. You won’t be any happier if your lighter wheel requires a more extensive tire that causes all the more moving obstruction in any case. Know that if your new wheel requires the tires to have a shorter side divider, this will bring down your load limit.

Every single geographical location will have its own type of compatible tyre, for example, there is the best tyre for UAE hot weather or on the contrary for the cold weather in Alaska. You must always keep your geographical location in mind while purchasing a tyre.

Wheel alignment

Toe setting on the steering axle is the most critical aspect of wheel arrangement. An unnecessary positive or negative toe can cause scouring and shoulder wear to the tire and excessive fuel consumption.

Toe can be communicated as a precise calibration of wheels. Tow-in is the term utilized when the main edge of the two front tires is nearer together and toe-out is the articulation utilized when the trailing edge of the two front tires are closer together. while zero toe is the term utilized when the wheels are parallel.

For each one kilometre wheel misalignment causes the vehicle to drag few meters sideways hence forcing the driver to keep the truck in a straight line by turning a steering wheel little, hence, causing flexing and scour to the tire as well as excessive fuel consumption.

What is the Fuel efficiency rating?

The fuel efficiency of a tyre is evaluated on a shading coded scale from A to G, A ( forest green) stands for the best fuel efficiency rating and G (red) being the most noticeably low fuel efficiency rating.

Extra tips

Here are some extra tips for getting the most mileage from your tyres:

• Keep your tyres appropriately inflated. (A placard on the driver’s doorjamb discloses to you the right pressure for your tyre.)
• In any case, check the tyre pressure frequently; do this when the tyres are cool.
• If you were content with the tyres that accompanied the vehicle when it was new, think about supplanting them with the same set since default tyre have low rolling resistance.
• Before purchasing substitution tyres, search for tyres that have low rolling resistance, are fuel economy and have great overall performance.
• Always drive in the highest gear possible

Conclusion

Many aspects affect fuel efficiency including tyre pressure, load on the vehicle, wheel alignment and driving style. If someone uses eco-friendly driving techniques as discussed in the article above, great mileage can be achieved.

In case you are unsure about the best economical tyre for your vehicle its always a best choice to visit a nearby mechanic for advice.
