SHERIDAN, WYOMING -- June 24, 2026 -- Yokohama Rubber Co., Ltd. has begun supplying its ADVAN Sport EV A/S V35 tires as original equipment for Porsche AG's fully electric Cayenne Electric and Cayenne Turbo Electric SUVs, which launched worldwide in November 2025. The fitment covers two staggered sizes — 255/55R20 110V front and 305/45R20 116V rear — and extends a supplier relationship that dates back to 1988. For Porsche's Cayenne line, Yokohama Rubber's ADVAN brand has been standard equipment from the first-generation model through the current fourth-generation electric variants.
ADVAN Sport EV A/S V35 Co-Developed With Porsche for Electric Cayenne Homologation
The ADVAN Sport EV A/S V35 supplied to Porsche carries the "NG0" sidewall mark, indicating Porsche's own technical approval. That designation reflects a co-development process specific to the Cayenne Electric models rather than an off-the-shelf fitment. The tire also bears Yokohama's proprietary "E+" sidewall mark, which the company uses to identify products engineered specifically for electrified vehicles.
Co-development with an OEM at this level requires the tire to meet performance thresholds the automaker sets independently of general market specifications. The result here is a compound tuned to hold low rolling resistance while simultaneously reaching a high-level balance of dry grip, wet grip, and snow performance — three performance axes that typically involve engineering trade-offs.
All-Season M+S Certification Widens Usable Conditions Across EV Markets
The ADVAN Sport EV A/S V35 meets the M+S (Mud & Snow) standard, qualifying it for use in markets and regions where all-season capability is a purchase requirement or regulatory threshold. Yokohama Rubber describes the tire as developed for driving across a wide range of road conditions, including shallow snow. The company notes explicitly that it does not qualify as a winter tire and cannot substitute for studless or dedicated winter products on icy roads or in heavy snow.
That distinction matters for fleet and retail buyers. An ultra-high-performance all-season tire rated M+S covers a practical daily-use envelope for most EV drivers in temperate or mixed climates without requiring seasonal tire changes. It does not, however, eliminate the need for a dedicated winter set in severe-weather markets.
Low Rolling Resistance and Cabin Quietness Engineered for Premium EV Expectations
Premium electric SUV buyers apply different benchmarks than those used for internal combustion vehicles. Cabin quietness, in particular, receives more scrutiny in an EV because road and tire noise is no longer masked by engine sound. The ADVAN Sport EV A/S V35 was designed with both low energy consumption and quietness as primary targets — attributes Yokohama Rubber describes as appropriate to the premium EV segment.
Handling stability was also addressed through engineering changes specific to this build. Yokohama Rubber optimized belt cover rigidity and tread contact area to improve stability, targeting the handling demands of a large, performance-oriented electric SUV. The Cayenne Electric and Cayenne Turbo Electric represent high torque loads relative to comparable combustion-powered models, placing additional stress on tire structure at launch and during sustained cornering.
ADVAN Brand Has Supplied Every Cayenne Generation Since the Model's Debut
Yokohama Rubber's history with Porsche OE supply is one of the longer continuous relationships in the premium tire segment. The company received Porsche's technical approval for the first time in 1988, when the YOKOHAMA A-008P was fitted to the 911. Since then, Yokohama tires have been installed as original equipment across multiple Porsche nameplates — the Cayman, Boxster, Cayenne, and Panamera.
For the Cayenne specifically, ADVAN has been the designated tire brand from the first generation through to the current fourth. The electric Cayenne now continues that sequence. No generation gap has occurred between the combustion-era fitments and the new EV variants.
YX2026 Strategy Targets Higher OE Share for ADVAN and GEOLANDAR Flagship Brands
Securing OE fitment for the electric Cayenne is also a direct output of Yokohama Rubber's three-year medium-term management plan, Yokohama Transformation 2026, running from 2024 through 2026. Within that plan, the consumer tire business aims to increase the sales ratio of high-value-added tires. OE placements with premium automakers are identified as a primary vehicle for that objective.
Two brand families are central to the OE push: ADVAN, Yokohama Rubber's global flagship for passenger and performance applications, and GEOLANDAR, the company's brand for SUV and pickup truck fitments. The Cayenne Electric supply deal contributes directly to both the ADVAN OE volume target and the broader YX2026 commercial objectives. It also positions the company in the growing premium electric SUV tier as automakers accelerate electrification across flagship model lines.
