EV Tyres Can Extend The Range By 10%
Sunday, 5. February 2023
Drivers of electric vehicles (EVs) can boost their battery range by up to 10% when using EV-specific tyres, says Michelin.
However, research conducted by the tyre manufacturer showed that most drivers are unaware that EV-specific tyres are available, with three-quarters (72%) of drivers in the dark.
John Howe, managing director for UK and Ireland at Michelin, says that EV-specific tyres “can enhance battery range, allowing drivers to travel further per charge”, but also “last longer on an electric car than a standard tyre”.
Further research also revealed that the increase to battery range is viewed by respondents as the main benefit of EV-specific tyres (35% of drivers), with the second most important benefit proving to be that EV-specific tyres last longer on an EV than a standard tyre (one in five respondents).
Howe continued: “A great deal of innovation and research goes into producing a tyre that can increase the range of an electric car.
“It requires the incorporation of several new tyre technologies to lower rolling resistance, increase efficiency and optimise the handling characteristics of electric cars.
“However, to truly get the most out of an EV, drivers should ensure they are making use of every opportunity available to them. To this end, we have provided our expert-recommended Top Tips for increasing EV battery range.”
MICHELIN’S TOP TIPS FOR INCREASED EV RANGE
1. DRIVE MORE SLOWLY AND SMOOTHLY
Electric cars are notoriously faster off the line than their petrol or diesel equivalents, but it is wise to limit full throttle accelerations to not only stay safe on winter roads, but also to extend your EV’s range. Where possible, keep your speed under 60 mph; as speeds increase, drag and rolling resistance increases too. Utilise your car’s “Eco” mode, if it has one.
2. USE EV-SPECIFIC TYRES
Electric cars can perform with a suitable standard tyre – they don’t have to be EV-specific tyres. However, if you are keen to maximise range, reduce noise levels or embrace the full performance of your car, EV-specific tyres can allow you to travel further on a full charge. Whichever tyres you choose, make sure they are inflated according to the manufacturer’s guidance, as improperly inflated tyres can reduce range, accelerate wear and pose a safety risk.
3. MAKE THE MOST OF REGENERATIVE BRAKING
Use your EV’s regenerative braking function as you come to a stop to harness the energy generated as the car slows down. By using the brake pedal less and using regenerative braking instead, you can extend the range of your car.
4. ONLY USE THE HEATER WHEN YOU NEED IT
The heating system can drain your EV’s battery – switch it off if you don’t need it. Some EVs allow the driver to pre-heat the car while it’s plugged in, but even this can consume energy before your journey has begun, so be mindful of this when aiming for the maximum range from your EV in winter.
5. TRAVEL LIGHT AND REMOVE THE ROOF RACK
Reducing a vehicle’s weight will improve efficiency and therefore range. So, remove any unnecessary items from the back seats or the boot, especially if they are weighty. Roof racks and other accessories will cause additional aerodynamic drag which will reduce your EV’s range, especially at high speeds when drag increases significantly.
6. CHECK THE LABELS ON YOUR TYRES
On new tyres, the EU Labelling can indicate the specific qualities that a tyre possesses. For example, choosing a tyre rated A or B for rolling resistance will help you to maximise the range of your EV.
