These pre-mounted tires are specifically engineered to upgrade the performance of the Kyosho Mini-Z 4x4 MX-01 series micro crawlers. Featuring the highly detailed and aggressive Interco Super Swamper tread pattern, they provide exceptional grip and articulation over diverse off-road terrain, from rocks to loose dirt. Each tire includes a precisely integrated internal weight of 33 grams, significantly lowering the vehicle's center of gravity to enhance stability, improve climbing prowess, and prevent rollovers on challenging obstacles, making them a crucial upgrade for serious trail enthusiasts.
