The forthcoming Lucid Air sedan from luxurious electrical automobile startup Lucid Motors can be one of many world’s most superior electrical autos, proper right down to the tires its will journey on.
The Air sedan will include a set of high-tech tires developed by Italian tire producer Pirelli. The Pirelli P ZERO tires are made particularly for electrical and hybrid autos, with additional load capability to help the extra weight of the automobile’s battery pack and low rolling resistance that assist improve vary.
The tires for the Lucid Air have been collectively developed by Perilli and Lucid Motors to completely meet the required efficiency requirements. To determine the particular design for Lucid Motors the tires can be marked “LM1” on the sidewalls.
The Lucid Air would be the very first automotive to make use of the brand new Pirelli HL tyres. The Pirelli P ZERO for this mannequin can be accessible in two sizes, 245/35R21 99 Y XL for the entrance axle and HL 265/ 35R21 103 Y XL on the rear axle.
“Lucid Air represents a technological breakthrough when it comes to effectivity and efficiency. The brand new Pirelli HL tyres are integral to reaching such benchmarks,” mentioned Eric Bach, SVP of Product and Chief Engineer at Lucid Motors.

All passenger automotive tires offered are rated for traction, temperature, put on and cargo. These rankings are specified by the producer and differ considerably from automobile to automobile. For instance a Porsche sports activities automotive would possibly require a excessive efficiency tire with the next pace ranking that the corporate’s engineers selected to supply elevated traction and dealing with in turns.
Nonetheless electrical autos can weigh greater than twice that of a gas-powered mannequin. The Tesla Mannequin S weighs over 4,900 lbs, whereas a gas-powered sedan just like the 2021 Toyota Camry weighs as much as 3,572 lbs. So matching the proper load ranking is necessary for security. It is often known as the “tire load index” and is often represented by a numerical designation between 70 and 126.
A load index of 70 can safely help 739 lbs, whereas a tire with a load index of 126 is designed to help 3,748 lbs. A standard load index of 99 signifies that every tire can safely help 1,709 lbs. These are thought of to be additional load (XL) tires and are designed for autos that may carry extra weight.
Pirelli’s new EV and hybrid automobile tire will options the HL (excessive load) marking on the sidewall as a sign of its means to soundly help 20% extra weight in comparison with an ordinary tire and 6-9% extra weight than an additional load XL tire of the identical dimension.
SUVs and pickups designed to hold extra weight sometimes include XL tires. These tires have stiffer sidewalls than regular tires, which permits the tires to help the extra weight of heavier autos and payload.
“The seek for cutting-edge technical options has all the time been on the very coronary heart of Pirelli’s enterprise. The eye we dedicate to all new types of sustainable mobility now leads us to know-how that’s able to anticipating the longer term calls for of automotive producers for his or her new electrical and hybrid autos, which more and more require specialised efficiency from tires,” mentioned Pierangelo Misani, Pirelli’s Senior Vice President of R&D and Cyber.
The P ZEROs tire for the Lucid Air will even embrace Pirelli Elect and Pirelli Noise Cancelling System (PNCS) applied sciences, which have been additionally included on the Pirelli tires for the Porsche Taycan sedan.
Pirelli Elect provides low rolling resistance to extend vary, lowered rolling and noise to maximise consolation, whereas on the identical time providing elevated grip for the immediate torque produced by an electrical powertrain.
Electrical autos with their practically silent powertrains may switch noise from the tires to the cabin, so Pirelli added sound-deadening supplies to the within of the tire, which is what Tesla has executed for its autos.
The PNCS noise decreasing know-how helps deaden air vibrations that will in any other case be transmitted to the within of the automobile. The advantages of this method will be felt each inside and out of doors the automotive, in line with Pirelli.
For an ultra- luxurious electrical automotive just like the Lucid Air, rising the consolation of passengers is necessary.
The primary Lucid Air fashions can be delivered to reservation holders later this yr.
