YOKOHAMA announced today that it is supplying its GEOLANDAR X-CV (Pattern No. G057H) tyres as original equipment (OE) to Mazda Motor Corporation for use on the car manufacturer´s new crossover SUV, the MAZDA CX-70, sales of which were launched in North America in April 2024. The tyre size is 265/55R19 109V.

*The CX-70 is not sold in Japan.

The GEOLANDAR X-CV tyre being supplied as OE represents a new standard in highway terrain tyres that YOKOHAMA developed to meet the M+S (mud & snow) standard for high-performance crossover SUVs, which have increasingly focused on high-speed performance and manoeuvrability in recent years. In addition to contributing to superior handling performance and a comfortable ride, the tyre also achieves low rolling resistance.

The tyres being supplied as OE for MAZDA CX-70 were developed by utilizing specialized tuning to match their tread pattern, profile, and tyre structure to the vehicle characteristics, while also using YOKOHAMA’s proprietary HAICoLab*, an AI-based development framework that aims to foster new discoveries and digital innovation by merging human inspiration and creativity with AI’s enormous data processing capability. To achieve the highly quiet ride, an optimal pitch sequence was obtained using evolutionary computation (genetic algorithms), one of the technologies incorporated in HAICoLab. The innovative technologies applied in development of the tyres are based on new knowledge obtained by collecting actual data and virtual data generated by simulations and then using AI’s predict, analyse and search functions.

* An acronym for “Humans and AI ColLaborate” for digital innovation

The MAZDA CX-70 is the two-row mid-size SUV that offers either an inline-six turbo with a mild hybrid or a plug-in hybrid powertrain. In addition to its superior environmental and safety performance balanced with the joy of driving culminating from Mazda's signature human-centric philosophy, the CX-70's design and features complement customers' active lifestyles.

Under YOKOHAMA’s three-year (2024–2026) medium-term management plan, Yokohama Transformation 2026 (YX2026), the consumer tyre business aims to maximize the sales ratios of high-value-added tyres. One of the key initiatives under this strategy is promoting the global flagship ADVAN brand tyres and the GEOLANDAR brand tyres for SUVs and pick-up trucks as original equipment for new cars.
