The market for electric and hybrid vehicles is constantly expanding. The ability to circulate freely in city centres, zero emissions and low noise pollution are just some of the benefits. The first Pirelli tyre with a high load index and “HL” on the sidewall, dedicated primarily to electric or hybrid cars and SUVs was developed to meet this trend. Designed to support the weight of battery-powered vehicles, the new tyre can be fitted on heavier cars, promoting low rolling resistance and high driving comfort.

The new tyre has HL (high load) printed on the sidewall in front of the size designation and can support 20% more weight on the ground than a standard tyre and from 6% to 9% more than an XL tyre of the same size.

The US-based Lucid Air will be the first car to fit the new Pirelli HL tyres. The new luxury electric sedan, which will be produced and sold in the United States soon, will be kitted out with size HL 245/35R21 99 Y XL Pirelli P Zero tyres on the front axle and size HL 265/35R21 103 Y XL tyres on the rear axle. Set apart from the conventional rules of car design, Air redefines the shape, proportions and dimensions of a luxury sedan with craftsmanship recognisable in every detail. In line with the Pirelli Perfect Fit strategy, the P Zeros for Lucid Air were developed together with the carmaker to fully meet the performance requirements of the Lucid and will display the LM1 marking on the sidewall to identify the specific design for the American brand


The new P Zeroes will also feature Pirelli Elect and PNCS technologies. The tyres in the Pirelli Elect range offer low rolling resistance to the benefit of range, low rolling noise to maximise comfort and a compound to provide immediate grip and handle the transmission stresses when starting, together with a structure designed to sustain the weight of the battery pack.

To further enhance interior comfort, PNCS technology features a special sound-absorbing material placed in the tyre cavity to dampen the air vibrations that would otherwise be transmitted to the passenger compartment with a consequent reduction in tyre-rolling noise, producing an additional benefit for the driver and passengers.
