The Science Behind Yokohama Tire’s GEOLANDAR A/T4® and Its Aggressive Center Blocks

Jake drives a Subaru Forester. Most days, it’s routine - errands, commutes, kid pickups. But on weekends, he trades pavement for trails. Dirt, gravel, mud. He pushes his Forester just far enough to feel free.

The first time he took his stock tires into the hills, they slipped. Spun on loose gravel. Struggled in shallow mud. That’s when he made the switch to Yokohama Tire’s GEOLANDAR A/T4®.

What Changed

Jake picked up a set in 17-inch, perfect for his Forester. The difference was immediate. On his next off-road run, he noticed a grip he hadn’t felt before. The tires bit into dirt and didn’t flinch in tight corners.

The reason? Aggressive center blocks.

Why Center Blocks Matter

Most people think off-road traction comes from the edges of a tire. But on loose terrain, it’s the center that makes first contact. That’s where the GEOLANDAR A/T4 excels.

The GEOLANDAR A/T4 uses staggered, angular blocks down the center of the tread. They’re deep. They’re rigid. And they’re positioned to claw into unstable ground.

Jake noticed it on a rocky incline. His Forester used to slide there. With the A/T4s, the tires held their line. He didn’t have to adjust mid-climb.

Real Engineering, Real Results

• Rigid central lugs maintain shape under pressure.
• Deep block edges dig into soft terrain for a forward bite.
• Wide spacing clears mud and debris with each rotation.

Confidence You Can Trust

On-road, the A/T4 is smooth. Off-road, it holds firm. The balance is what makes it perfect for dual-purpose crossovers like the Subaru Forester.

Jake still takes the same trails. Only now, he takes them with confidence.

If you’re a Forester driver looking for better trail performance without losing daily comfort, the GEOLANDAR A/T4 with Aggressive Center Blocks delivers.
