The tire employs uniquely developed 3-D shaped sipes. The sipes, which are shaped into a three-tier pyramid, suppress breakdown of the tread block. This contributes to exceptional stiffness on dry surfaces and outstanding edge effects on wet surfaces.

We enhanced the road-hugging properties of the shoulder and lug grooves. This ensures exceptional traction in off-road conditions. Optimizing the shape of the entire grounded portion of the tread also improves wear resistance.
The design of the shoulder section has been overhauled as well. In addition to improving the tire's follow-up durability, the appearance gives an aggressive feel.
For the design, the lug grooves get narrower as they approach the center section and gradually wider as they approach the grounded edge of the shoulder. This helps to beat down off-road surfaces for greater traction.
Compound exclusively for the GEOLANDAR A/T G015 that is highly wear resistant and resistant to temperature changes.
1Triple Polimer 2Orange Oil 3Silica (A)The compound is a blend of three types of polymer with differing functions.All of the functions required of the compound have been improved, namely wear resistance, flexibility in low temperatures and resistance to cuts and chipping. (B)Blending in Orange Oil realizes a flexible compound at the micro level. This improves tracking performance over minute undulations in the road surface as well as enhancing grip strength on both wet and dry roads. (C)For silica, which enhances performance in the wet, it is critical that particles inside the compound are dispersed evenly. YOKOHAMA promotes the uniform dispersion of silica through its unique compounding technology. (D)Image
Rubber stays soft in low temperatures
Ordinary compounds stiffen up in low temperatures, which tends to compromise grip. The new compound stays softer in cold temperatures, making it more adaptable to winter roads.
The tire tracks minute undulations in the road for superior grip
The use of Orange Oil compound enables the tread rubber to stick closely to undulations on the road surface at the micro level, thereby ensuring exceptional grip in the wet.
A triple polymer boosts wear resistance
Wear is more pronounced in summer when road surface temperature is high. The new compound blends polymers that are resistant to wear to ensure excellent anti-wear performance even in hot weather.

Rather than have uniform block pitch in a circumferential direction, the tire employs pitch sequence of differing size. The frequency of the pitch is dispersed to reduce pattern noise. There is also less burden on the block, which contributes to a reduction in uneven wear.
