Goodyear develops tyres for electric Lexus concept

Goodyear has developed concept tyres for the Lexus LF-30 Electrified, a fully-electric concept car which marks the Japanese brand’s 30th anniversary.

The vehicle was originally presented sitting on four bespoke Goodyear concept tyres at the 2019 Tokyo Motor Show. It was presented again at the start of this month at Lexus’s live press conference during the virtual press day of the Geneva Motor Show.

Goodyear says the concept tyres support EV motors and are designed to improve the overall comfort and performance of the car.

Available in size 285/35R24, the LF-30 Electrified concept tyre includes several innovative features:

EV motor cooling: Drawing on Goodyear’s expertise in aerodynamics, the concept tyres are designed to improve the cooling of the EV motors. Cool air enters through the front bumper intake and fins on the tyres drive the flow towards the electric motor positioned behind each wheel. The hot air produced by the EV motor is then expelled towards the outer edge of the rim of the LF-30 Electrified.

Reduced aerodynamic drag: The tyre design along with the outer tyre shape would improve the Lexus’ aerodynamics by reducing drag, resulting in higher efficiency and battery range.

Noise reduction through biomimicry: Goodyear says it found inspiration in nature when designing the concept tyres. The leading edges of the cooling fins are covered with fine velvet like on the wings of an owl, which enables the predator to silently catch their prey at night. Through this biomimetic solution, the rolling noise of the tyre would be reduced to a minimum.

“We are proud to have worked on this project with Lexus, a company that has been pioneering innovations in mobility for 30 years”, explains Mike Rytokoski, vice-president and chief marketing officer, Goodyear Europe, “This collaboration demonstrates once again the critical role tyres can play in shaping the future of electric mobility.”
