Real-world test data, everyday impressions, and plain-English breakdowns — from a former Bridgestone test engineer.
The BFGoodrich KO2 has been the benchmark Off-Road A/T tire for more than a decade, trusted across the US and Canada for its 3-ply sidewalls, trail toughness, and snow-certified 3PMSF traction. The newer BFGoodrich KO3 keeps that DNA but improves snow grip, extends tread life, and sharpens handling, making it the clear evolution for drivers debating KO2 vs KO3. The Yokohama Geolandar AT4, as an On-Road AT Tire, meanwhile, enters from a different angle — emphasizing modern road manners, stronger wet and ice braking, and a lighter steering feel, while still carrying adventurous A/T styling.
That’s the choice buyers face — KO2’s proven legacy, KO3’s updated balance, or Yokohama’s road-friendly refinement. In the sections ahead, I’ll break down how they compare across dry, wet, snow, and off-road testing. You can also line them up in our All-Terrain Tire Decision Tool for quick recommendations tailored by SUV, CUV, or truck class.
Quick Look
The Yokohama Geolandar A/T4 is the comfort commuter’s all-terrain. It brakes shorter on dry and wet pavement, feels smoother in daily turns, and stays impressively quiet on the highway. With its 3PMSF rating, it surprises in winter commutes—holding its own in packed snow and light ice—while still looking the part of an A/T. Its trade-off is durability and trail grit, but for suburban drivers who value calm road manners, it’s a standout.

The BFGoodrich KO3 is the modern benchmark, balancing toughness with refinement. It grips earlier on ice than the KO2, steadies heavy rigs under towing, and shortens winter stops, while keeping its legendary off-road bite. Noise is present but livable, and its versatility makes it ideal for regions where snow, storms, and trails all collide.
The BFGoodrich KO2 remains the veteran workhorse. Louder, firmer, and longer in the wet, it still outmuscles rivals in deep snow and trail abuse. Built with armored sidewalls and proven longevity past 50k miles, it’s the tire you trust when durability is the priority and comfort is secondary.
