The Geolandar family of all-terrain light truck tires from Yokohama has been a favorite with drivers everywhere for decades. The Geolandar product line has rightly built a reputation for top quality, durability, innovation, and the right balance between tough, tenacious off-road performance and civilized, composed behavior on the street (without making any real sacrifice in either realm).

The Geolandar A/T4 G0188 is one of the latest iterations of the Geolandar line, and it’s more or less an upgrade from the popular Geolandar A/T G015 model, building on all the successful ideas of that proven tire line. With its great balance of off-road toughness and highway manners, it’s a real winner. Let’s go in and take a closer look at this Yokohama Geolandar A/T G018 review:

SimpleTire’s view on Yokohama Geolandar A/T4 G018 tires

Trucks and SUVs have come a long way in design and performance in the last 30 years, and the Yokohama Geolandar line has evolved right with them. The Geolandar A/T4 G018 is designed for the weight, torque, horsepower, handling performance, and overall driving dynamics of today’s trucks, and it’s showing itself to be a great fit.

The Geolandar A/T4 G018 is surprisingly composed and confident on the street or highway, with noise levels about what you’d expect with an automotive all-season tire and a little firm but forgiving ride. Yokohama’s Geo-Shield construction technology has long been a key feature of Geolandar tires, with its reinforced sidewall that stands up to the roughest treatment without flinching, resisting cuts, punctures, chips, and scrapes.

Not long ago, a few members of the SimpleTire team could take a trip to Central Texas to test-drive the Geolandar AT/4 G018 (mounted on Ford Broncos) over four trail modules with 1 to 1.5 hours on each trail. They were impressed with its control, durability, and tenacious grip, quote:

I thought that they handled phenomenally well, rock crawling, off-roading through loose rock & mud, riverbeds, etc... the time I got to let loose was the dirt speed track which I intentionally tried to fishtail the thing, and it stuck like glue

The stone ejectors on the Yokohama do a great job of self-cleaning the tread of mud and debris, ensuring that there’s always a clear section to dig in as the wheel turns. Stability and road manners on the highway are first-rate thanks to a rigid internal design that cuts down on tread squirm during hard maneuvers, and that robust center block design gives the Yokohama admirably solid straight-line stability. Finally, the Yokohama Geolandar A/T4 G018 features two separate sidewall designs, letting the driver select which sidewall will be flipped toward the outside to customize the truck’s aesthetics. Bottom line: the Geolandar A/T4 G018 has been anticipated for some time, and whether it’s rocks, mud, snow, sand, loose dirt, or a quiet boulevard, this is a tire that’s up to the task.
