Hiratsuka, Japan—The Yokohama Rubber Co., Ltd. announced today that it has begun supplying its ADVAN Sport EV A/S V35 tires as original equipment (OE) to Porsche AG of Germany for its fully electric Cayenne Electric and Cayenne Turbo Electric SUV models*1 that were launched worldwide in November 2025. The tire sizes are 255/55R20 110V for the front and 305/45R20 116V for the rear.

The ADVAN Sport EV A/S V35 is an ultra-high-performance all-season tire developed for premium EVs that is designed to handle driving in a wide range of road conditions*2 and meets the M+S (Mud & Snow) standard. Based on the ADVAN V35 all-season tire that was installed on the previous-generation Cayenne, this tire achieves a level of low electricity consumption and quietness appropriate for premium EVs. The sidewall of the ADVAN Sport EV A/S V35 bears Yokohama Rubber’s proprietary “E+” mark to indicate that it has special qualities suitable for electrified vehicles.

The tires installed on the new Porsche Cayenne electric models were co-developed with Porsche and bear the “NG0” mark on their sidewalls, indicating Porsche’s approval. They use a special compound that maintains low rolling resistance while achieving a high-level balance of dry and wet grip as well as snow performance. In addition, handling stability has been enhanced through optimization of belt cover rigidity and tread contact area.

Yokohama Rubber first obtained Porsche’s technical approval in 1988. Since the YOKOHAMA A-008P was installed on the 911, Yokohama Rubber has supplied tires as original equipment for many Porsche models, including the Cayman, Boxster, Cayenne, and Panamera. For the Cayenne, Yokohama Rubber’s global flagship tire brand ADVAN has been used continuously from the first-generation model through the current fourth-generation model. The ADVAN Sport EV is also being used on the new Cayenne.
　
Under Yokohama Rubber’s three-year (2024–2026) medium-term management plan, Yokohama Transformation 2026 (YX2026), the consumer tire business aims to maximize the sales ratios of high-value-added tires. One of the key initiatives under this strategy is promoting the global flagship ADVAN brand tires and the GEOLANDAR brand tires for SUVs and pickup trucks as original equipment for new cars.

*1: The previous-generation gasoline and hybrid Cayenne models are still being sold following the launch of the new electric ones.
*2: Although this tire was developed to also be capable of driving in shallow snow, it cannot be used as a winter tire. If you are planning to drive in snowy areas or on icy roads, the tires will need to be replaced with studless tires or other winter tires.
