Yokohama Rubber has confirmed that its Geolandar A/T G31 and X-CV tyres are now being fitted as original equipment on Toyota’s new 4Runner in North and Latin America which was launched at the beginning of this year.

The Geolandar A/T G31 size 245/70R18 110H are fitted in Latin America and the Geolandar X-CV sizes 245/70R17 110T and 265?55R20 113V are fitted in North America.

The GEOLANDAR A/T G31 are all-terrain tyres with impressive road handling ability in any off-road situation. Whilst for environmental performance, improvements have been made to fuel efficiency and quietness. Also, pattern optimization, profile, and structure of the tyres being supplied provides a high level of both comfort performance and steering stability.

The GEOLANDAR X-CV tyres represent a new standard in highway terrain tyres focused on high-speed performance and versatility and are specially tuned to achieve a significant reduction in rolling resistance while also providing excellent steering stability and comfort and obtaining superior reliability in severe driving environments.

The tires being supplied as OE for the 4Runner were developed using Yokohama Rubber’s proprietary HAICoLab, an AI-based development framework that incorporates new discoveries and digital innovation by merging human inspiration and creativity with AI’s enormous data processing capability. 

The development of the pattern design includes evolutionary computation (genetic algorithms), one of the technologies incorporated in HAICoLab. 

The innovative technologies applied in the development of these tires are based on new knowledge obtained by collecting actual data and virtual data generated by simulations and then using AI’s predict, analyze and search functions.

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.
