If you recently added a new set of tyres and noticed a slight change in your fuel consumption, you are not the only one. The truth is, each set of tyres affects each vehicle differently. Most importantly, tyres are a direct factor when it comes to fuel economy and one that has an impact on your fuel savings, especially in the long run.
Being more generous to your wallet is something that everyone would do in challenging times like these. Choosing tyres that do not contribute to major fuel expenses is something that our team at TyresOnline can definitely assist you with. Below, we are sharing our simple guide with tips you should take into account when buying new or replacing your existing tyres with another set.
As an overview, we are going to talk about the most important factors that lead to more fuel expenses, which include:
- Rolling resistance: The higher grade your tyres have, the more efficient they will be.
- Tyre structure and size: Larger tyres sustain more air pressure, which is why they need more fuel to move the car. Similarly, models such as diagonal tyres are more efficient compared to radial ones.
- Tyre wear and pressure: Driving with worn out tyres puts a risk to your safety but also increases your fuel consumption. Same goes for underinflated or overinflated tyres.
Understanding Fuel Efficiency And Rolling Resistance
The best way to choose tyres that won’t drain your wallet and fuel tank is to opt in for a model that has the highest energy efficiency, or in other words, the best rolling resistance.
For those of you who are not familiar, tyre rolling resistance is the ratio between the energy input that goes into the movement of the vehicle, as well as the external factors that slow it down. So, the rolling resistance is influenced by the aerodynamic resistance, the weight of the vehicle, the tread’s structure and shape, as well as its micro-slip and pressure levels.
By law, tyres in UAE have viable labels, which provide drivers like you with information about their performance. If you are interested in tyres that have the lowest rolling resistance (which means the highest energy efficiency), you should consider ones with class “A” on their label. This is the best of the seven grades in rolling resistance vs. burning.
Understanding Tyre Structure & Size
Next in our list of things you should know is tyre structure. Tyres that have greater weight affect the level of combustion – meaning that the heavier your tyres are, the more energy your car will use to get you moving, which again translates to more fuel.
The construction of the tyres is another factor that many tend to forget. Diagonal tyres have higher rolling resistance compared to radial ones.
Aside from structure, choosing bigger tyres will also lead to greater fuel expenses, mainly because of the aerodynamic resistance, which gets reduced. Typically, drivers change the width of their rims for aesthetic purposes and change the size of their tyres, which is how the cost increases.
Tyre Wear & Tyre Pressure
Tyre wear and pressure are additional factors linked to fuel economy. Lower tyre pressure typically translates to tyres that are more deformed and bent, which leads to increased rolling resistance. In cases like these, the vehicle needs more power to move, which is why it uses more fuel.
According to a research, tyres that were reduced by 0.3 bar in pressure led to a 6% increase in rolling resistance. Another set of tyres which were reduced by 1 bar in pressure, led to a staggering increase of 30% in fuel consumption. So, tyre pressure and wear are one of the most important elements that determine the level of fuel consumption.
So, what should you think about when choosing your (new) tyres?
Now that you know the main factors behind fuel consumption related to your wheels and tyres, you should have a basic idea on what type of tyres you need for your vehicle. However, there are many other factors that you can’t control, and are equally important for optimal fuel economy.
We advise you to always:
- Choose a set of tyres that match your unique driving habits
- Choose tyres that have better grades and reviews
- Replace and rotate your tyres (seasonally)
- For city driving, look for braking distance, longevity, and fuel economy when choosing new tyres
- For road/highway driving, consider braking distance at high speeds, comfort, noise and handling as one of the main features
- For unpaved roads, look for tyres that are optimized to deliver solid off-road traction
- If you like quiet and comfortable rides, touring tyres with lower speed ratings can be your best choice
- If you like to feel every curve and accelerate/brake quickly, look for tyres with great handling or steering precision (which are usually high-performance sports tyres) and models with higher speed rankings
- Always make sure that your tyres are the best fit for your wheels
As you could read from above, there are things that we can do to control our fuel consumption. If your main goal is to drive from location A to location B and you are driving a normal car, you should always choose tyre models that are as close to the factory tyres and unique features of your car, rims, and brakes.
On the other hand, if you are a fan of sports driving, love to accelerate quickly, brake and drive in higher gears, you will likely experience greater fuel consumption than with regular driving. The goal here is to choose a set of tyres that can maximize your performance and give you the most optimal fuel economy for your specific vehicle. However, you should also have in mind that driving this way may also require a specific set of brakes for the best performance.
