Monster

The Monster tires are a set of unlockable wheels. They offer good speed, weight, and off-road, but bad acceleration and handling. The Monster tires have the best speed boost in the game along all of the kart parts, but the worst acceleration boost. They are tired with the Red Monster tires for the best off-road boost. They're also tied with the Red Monster tires, the Slick tires, and the Gold Tires, for the worst handling boost.
