The Geolandar A/T-S is Yokohama's On-/Off-Road All-Terrain tire developed for jeep, pickup truck and SUV drivers who want tires that combine a bold off-road attitude with a capable on-road aptitude. Geolandar A/T-S tires are designed to deliver long mileage and promote even wear while providing year-round traction, even in snow.
The Geolandar A/T-S uses a silica-enhanced tread compound molded into a symmetric design that combines sculpted shoulder blocks, rounded-edge intermediate blocks and staggered center blocks to blend off-road traction with on-road control. Dual interlocking pyramid sipes and multi-stepped grooves on the tread blocks maintain block rigidity to enhance wear and increase the tire's biting edges to provide traction in loose dirt and gravel as well as on wet and wintry road surfaces. Aggressive sidewall protectors are strategically located near the tire's shoulders to increase loose-surface bite while they help fight off sidewall cuts and abrasions from rocks and stumps. The tire's internal structure includes twin steel belts reinforced by spirally wound nylon on top of polyester body plies.
