TyreSafe: EV tyres are ‘significantly different’
“Drivers of electric vehicles must be aware of how different [tyres] could be to those on other cars, and when it’s time to replace the original tyres, owners need to ensure they are buying the right specification…”, according to TyreSafe chair Stuart Jackson. (Source: TyreSafe)
TyreSafe is advising owners of electric vehicles (EVs) to “pay close attention to the tyres they choose when the originals need replacing” because “increasingly, the tyres fitted are specifically designed for use on EVs and can be significantly different to the ‘normal’ tyres…”. Specifically, TyreSafe is warning EV owners that fitting the wrong type of tyre could result in “loss of range, extra noise, accelerated wear and the risk of failing while being driven, which could result in a serious incident”.
According to TyreSafe, “EVs are well-known for being heavier than their petrol or diesel equivalents, so an owner must be aware of their tyre’s load rating when a replacement is needed as well as maintaining the recommended tyre pressure at all times.”
Another consideration is the impact tyre choice can have on an EV’s range, due to its rolling resistance. TyreSafe’s advice? “A tyre should have the least rolling resistance as possible, however, as always, a balance needs to be struck as grip is essential for safety when it comes to braking. Minimising rolling resistance while providing adequate grip seems like a contradictory requirement but this is a key performance characteristic for EVs to ensure maximum range.”
The tyre also needs to be robust as EVs produce maximum power from standing. This places high demands on the rubber compound, which needs to be of the right mixture of components and have the appropriate tread pattern to provide a lifespan comparable with petrol or diesel vehicles.
Stuart Jackson, TyreSafe, Chair, commented: “Tyres are an extremely sophisticated piece of technology, which we all too commonly take for granted. However, drivers of electric vehicles must be aware of how different they could be to those on other cars, and when it’s time to replace the original tyres, owners need to ensure they are buying the right specification. Choosing a like-for-like tyre will allow EV owners to enjoy the full benefit of the electric car revolution and reduce the risks of an incident.”
