Electric Cars face more tyre problems

A recent study suggests that electric vehicles (EVs) may be more likely to develop wheel and tyre problems than petrol powered cars.

The research carried out by the British Vehicle Rental and Leasing Association (BVRLA) analysed data from more than 47 million MOT tests in the UK.

According to the findings the extra weight of EV batteries and the instant torque produced by electric motors can put greater pressure on tyres and wheels.

Why do electric cars put more pressure on tyres?

Electric cars use large battery packs that can weigh around 299 to 499 kilograms.  In some vehicles the battery can account for up to 25% of the car’s total weight.

Electric motors also deliver strong torque almost immediately when the car starts accelerating.

This quick power can place more force on the tyres potentially increasing wear and the risk of tyre related problems.

Older EV models show more issues

The study found that tyre related problems were more noticeable in some older electric vehicle models.  Certain EVs also recorded problems involving traditional friction brakes.

The BVRLA said some EV owners may face higher maintenance costs, particularly when tyres need to be replaced.

Premium tyres can cost hundreds of pounds adding to the overall running expenses. The report linked the higher rate of tyre problems mainly to the extra battery weight and instant low-speed torque of electric vehicles.
