About Yokohama Geolandar A/T4 G018 305/70R17 121/118R

The Yokohama Tyres Geolandar A/T4 G018 is built around an aggressive all-terrain tread rather than a road-focused SUV pattern. Its 2-in-1 centre blocks use different lug-groove arrangements to create multiple working edges, while zig-zag deep grooves open the tread for loose-surface traction and water evacuation. Deep and wide shoulder grooves extend the tyre's ability to work on softer terrain, and vertical protrusions within the voids help reduce the tendency of mud and stones to remain packed into the tread. 1

Steering Feel and Heavy-Duty Road Behaviour

At 305 mm wide with a 70-series sidewall, this is a substantial tyre, so steering will naturally feel more planted and deliberate than with a smaller highway-oriented fitment. The square profile and firmly grounded lug blocks help maintain a stable contact patch when a pickup is carrying weight or travelling across uneven ground. On the highway, the construction is intended to retain usable handling rather than behaving like a loose, flexible mud tyre. The E load range and 121/118 service description make this configuration particularly relevant to trucks where load capacity and structural strength are important considerations. 2

Off-Road Traction, Wet Roads and Snow

The main reason to choose this pattern is its ability to keep working when pavement ends. Large centre blocks, zig-zag grooves and open shoulder areas create multiple edges for gravel, dirt and uneven surfaces. Deep wave-shaped sipes add additional biting edges on wet surfaces, while the tread's deep and wide shoulder grooves are intended to support traction in snow and loose terrain. The A/T4 carries the Three-Peak Mountain Snowflake severe-snow-service qualification, so this is more than a cosmetic all-terrain tread for drivers who regularly encounter winter conditions. 3

Comfort, Noise and Tread Durability

An aggressive all-terrain tyre cannot be expected to be as quiet or as smooth as a highway tyre, particularly in a large LT size such as 305/70R17. Yokohama has nevertheless used single-pitch shoulder blocks to help reduce pattern noise, while the contact shape is designed to keep the tread blocks firmly grounded for a balance between traction and tread life. The dual-sidewall design also gives the A/T4 a choice of sidewall appearance while using large side blocks to contribute to off-road traction and durability. 4

Who Should Choose This Configuration?

This specification makes sense for a pickup or truck owner who spends meaningful time on dirt roads, rocky trails, construction access roads, gravel, sand or mixed terrain but still needs predictable highway behaviour between trips. The 121/118 load index provides a maximum single-tyre load of 3,195 lb, while the E load range and 65 psi maximum inflation specification reflect its heavy-duty LT construction. The tyre has an 8 to 10-inch approved rim-width range, with a 9-inch measuring rim used for published dimensions. 5

For an owner who spends almost all of the time on smooth urban highways, a highway-terrain tyre can provide a quieter and more road-focused driving character. The Geolandar A/T4 G018 instead makes more sense when durability, loose-surface traction and all-weather versatility are part of the requirement. Yokohama lists a 55,000-mile limited treadwear warranty for LT-metric A/T4 sizes in the U.S., although warranty eligibility and terms depend on market and usage conditions. For this 2025 listing, the referenced LT305/70R17 specification is shown as produced in the Philippines, while Yokohama is a Japanese tyre brand; country of production can vary by batch. 6

For buyers comparing heavy-duty all-terrain options, the Yokohama approach here is clearly centred on maintaining usable pavement manners without giving up the aggressive tread hardware needed away from the road. If your priority is a truck tyre capable of regular mixed-terrain work rather than occasional gravel use, this configuration offers the combination of deep tread, reinforced construction and substantial load capacity that makes it well suited to demanding ownership. Dwbtyres can provide this specification for customers looking to buy car tyres in UAE while checking that the 305/70R17 size, load rating and vehicle clearance are correct for the intended truck.
