Due to their worn tires, electric and hybrid cars fail MoT inspections more often than petrol or diesel vehicles, but they do so more frequently.
Analysis of 49.9 million MoT tests performed between 2019 and 2018 reveals that 14.84% of hybrid vehicles and 17.87% of fully electric vehicles failed the test first time.
The rates for petrol and diesel vehicles were 20.1 and 23.1% respectively.
The main difference is believed to be because conventional motors have more moving parts than electric vehicle (EV) power plants, which means there is more room for error.
However, the carwow marketplace survey also found that, compared to 28.2% of diesel cars and 25.9% of petrol cars, 36.2% of electric vehicles and 33.2% of hybrid vehicles that have failed the first time had tires below the legal requirement.
The quick torque of electric power and the added weight of a large battery, experts say, are two factors that contribute to tire wear.
“The quick torque and extra weight are brutal on the tires – that should be a huge red flag for drivers to inspect their tyres,” said carwow’s Hugo Griffiths.
But in response to the study’s findings, AA President Edmund King said, “Most electric vehicle tires are specialized and constructed from more durable compounds with stronger sidewalls. Driving habits and road conditions have the greatest impact on tire wear.
RAC’s Simon Williams said: “We think their higher failure rate for damaged tires may have more to do with driving habits than anything else.”
Because electric cars accelerate faster than the majority of gasoline or diesel vehicles, drivers who take advantage of them will wear out their tires faster than those who drive more cautiously.
