Electric and hybrid cars are accelerating in popularity, with more battery-powered motors registered in the past year than the previous five combined.
While great for the environment, their relative freshness to the market means buyers don’t pay as much attention to details as they are to petrol and diesel vehicles.
And it turns out that buying an EV with the wrong kind of particular part can prove disastrous.
thank you expert Continental Tires We’ve uncovered exactly what to look for when searching for the right type of rubber – and where things can go wrong.
According to the team, most electric vehicles on the road are still relatively new and have yet to require any major servicing, maintenance, repair or replacement parts.
But surprisingly, when the time comes, there are some specialist requirements to consider, especially when it comes to tires.
The batteries in EVs can make them up to 30 percent heavier than internal combustion vehicles.
This, coupled with the increased torque that gets them off the line immediately, puts a lot of pressure on the rubber.
Fortunately, there are plenty of tires on the market that have been designed with EVs in mind.
However, it’s important for drivers to know when it comes to changing a tire on their EV, or if they’re buying an old, used EV and want to make sure it’s fitted with the right equipment. So what are the features to pay attention to?
The top three areas of concern are the increased weight of the car, noise in the cabin and low rolling resistance.
1. Extra load
Having tires that can bear the weight of the car is always important, no matter what the motor.
But on an EV, the extra load on the battery also has to be taken into account.
You should check that the tires initially included with the vehicle are Extra Load (XL) tyres, with a load range developed to provide a greater load capacity than standard tyres.
In some cases, you may even find that heavy load (HL) tires are required.
The load capacity of the new HL tires amounts to a 10 percent increase over the more familiar XL standard.
Always go for a similar tire replacement that has the load capacity specified by the vehicle manufacturer.
Continental Tires has a easy guide To see what the load requirement is for your vehicle.
2. Cabin Noise
EVs are generally much quieter than vehicles with standard internal combustion engines.
As a result, the noise produced by their tires coming into contact with the road surface is much more noticeable in the cabin.
Continental’s Continental technology, which uses a special layer of polyurethane foam on the inside cavity of the tire to absorb vibration and noise, is popular among automakers for its ability to reduce in-cab noise levels .
If your EV came with compliant tyres, you should make sure that the replacements you put in are also compliant.
3. Range Anxiety
Specially designed, low rolling resistance tires can help increase the range of an EV by up to 12 percent.
For new cars with a range of more than 250 miles, one tire EU Tire Label An ‘A’ rated tire can benefit from an additional 30 miles per charge compared to a ‘C’ rated tire.
Not only can this save you money on charging, but you will also be able to complete longer trips seamlessly.
Steve Howat, general manager of technical services at Continental Tire Group, said: “While some standard tires can be fitted to electric vehicles, there is no impact on performance, many others by lengthening braking distances, hindering range and increasing noise. reduce the risk of wasting the benefits that EVs bring – compromising the comfort, cost-efficiency and safety of the drive.
“And even within battery-powered vehicles, there isn’t a one-size-fits-all approach with tires.
“Performance requirements can completely vary from vehicle to vehicle, which is why we work closely with each manufacturer in the design phase of a new EV, to develop a tire that is tailored to its individual needs. be best suited for
“This also means that when it comes time to replace EV tires, it’s important to invest in premium, equine options that enable the vehicle to perform at its best while maximizing safety on our roads.”
