The Red Monster wheels are unlockable wheels in Mario Kart 7. They have good speed, weight, and off-road, but lack good acceleration and handling stats.
Comparing it to the Monster tires, the Red Monster's acceleration is a little bit better, yet it is slightly lighter. They are tied with the Monster tires for the best off-road in the game and are also tied with the Monster tires, the Slick tires, and the Gold Tires, for the worst handling.
