Yokohama Geolandar A/T4 G018 – an all-season profile product for powerful crossovers and SUVs, designed for drivers who require sports-like clarity of response from their vehicle without compromising on traction and durability. Its design is a response to the challenges of a high center of gravity and significant torque, focusing on stability, precision, and longevity.
Stability as the foundation
The key innovation is the proprietary tread profile with a variable radius of curvature. Unlike a classic arc, it forms an optimized, wider, and more even contact patch even at the design stage. When lateral acceleration occurs in a turn, this geometry works in conjunction with reinforced shoulder blocks with internal support. As a result, the contact patch does not deform, but retains its area and shape, which directly translates into exceptional directional stability, predictability of traction, and instant feedback through the steering wheel.
Silica for performance and durability
The "heart" of the tire is a high-tech rubber compound based on high-dispersion silica in combination with special polymers. This formula provides two critically important properties: first, it reduces hysteresis losses to improve fuel efficiency; second, it retains elasticity and viscosity properties over a wide temperature range. This ensures a consistently short braking distance on wet asphalt and levels out wear throughout the entire lifespan of the tread.
Tread architecture
The pattern features an asymmetric non-directional scheme with a clear zonation. The inner side with more frequent transverse grooves and blocks is responsible for efficient water drainage and anti-aquaplaning. The outer side is formed by massive, rigid blocks connected by stabilizing elements, creating a solid zone for maximum traction in turns. Multiple 3D lamellas and micro-grooves on the blocks increase the number of working edges, improving the initial response and traction in borderline conditions.
Key features of Yokohama Geolandar A/T4 G018:
- patented profile geometry that maximizes and stabilizes the contact patch for sports-like stability and predictability in any weather;
- reinforced internal elements in the shoulder area to minimize block deformation and maintain sharp steering;
- silicon-organic composition for balancing traction on wet, slippery roads, fuel efficiency, and wear resistance;
- asymmetric architecture for stable vehicle behavior on snowy sections;
- numerous lamellas and block structures that prevent deformation and increase the number of working edges for improved traction.
