The Right Tyre Size can Increase Your Car’s Mileage

The Right Tyre Size can Increase Your Car’s Mileage

Quite often we come across vehicles on the road with modified tyres and rims. Those bulky, wide tyres do look really impressive sometimes. And let’s be honest that irrespective of which car we drive, we have all thought of getting those larger tyres for our cars, jeeps and SUVs. But have you ever thought of the fact that larger tyres may not be good for your vehicle’s mileage?

Let us tell you why.

There are some very simple reasons – supported by science – which tell us why it is important to have the right sized tyres to get the best mileage. Since a vehicle is all about movement, laws of physics dictate its performance. In this particular case, it is called rolling resistance.

Moving a stationary object like a car requires energy, which is provided by the engine. The more resistance your vehicle has, the more fuel it burns.

So, what does that have to do with the tyres?

Apparently, everything.

Tyre Size

Wider tyres have more surface area and hence more friction with the tarmac – resulting in higher rolling resistance than the tyres size recommended by the vehicle manufacturer. This means, your car’s engine has to work harder to maintain the cruising speed, which increases fuel consumption.

This theory can easily be put to test by comparing mileages at highway speeds.

Tyre Weight

The second reason is an obvious follow up of the first one. A wider, bulkier tyre is also going to weigh more. And, as we know, the more weight you are pulling, the more energy you need. A tyre that is made for your car will be lighter, thus decreasing the weight and rolling resistance thereby increasing your car’s per kilometre fuel average.

Types of Wheels

Obviously, when you are changing to a larger tyre, you will be replacing the wheels with some fancy ones as well. In general, they are referred to as ‘Alloy Wheels’. Most stock wheels are made of steel – which is heavier than comparable alloys. So, if you replace the stock wheels with alloy wheels, it should help your mileage, right?

The correct answer to that question is NO.

Since, you are getting larger, wider tyres for your vehicle, the new alloy wheels also need to be larger. Thus, negating any fuel efficiency benefits you might have gained. On the contrary, most people end up buying alloy wheels which are even heavier than the stock steel ones, thus reducing the fuel efficiency.

How much of a difference does large tyres make to a vehicle’s fuel efficiency?

Several independent tests have shown that the difference can be as low as 10% in a controlled environment – where vehicle speed, air conditioning and other systems are kept constant. But for an average highway driver, the difference in fuel efficiency while driving with larger tyres can be as high as 25%. Moreover, the figure can go up even further when driving in heavy city traffic.

So, choose the best car tyre and wheel combination by consulting with tyre experts to keep running costs down and prolong engine life.

Our recommendation:

Getting new car tyres is always tricky. While stock tyres are optimised for the vehicle, they are also a cost-effective solution for the OEM, especially in the entry-level models. So, when it is time to get new car tyres, look for compatible high-performance tyres for your car. Our recommendation is the Apollo Alnac series if you are driving a premium hatchback or a mid-segment sedan. The Apollo Alnac 4G remains the tyre to beat for this segment. For SUV owners, the Apollo Apterra is the perfect tyre for traversing through desert sands and winter snows alike.
