Gold Tires

The Gold Tires are a special set of unlockable wheels in Mario Kart 7. They offer the exact same stat boosts as the Slick tires, except for that they give up some more acceleration to enhance weight. The Gold Tires are unlocked by collecting 15000 coins, or by getting a star rank on every GP cup for each engine class. Like the Slick tires, the Gold Tires offer the best speed boost, but they also offer the worst off-road boost. Additionally, they're tied with the Slick, Monster, and Red Monster, for the weakest handling boost in the game.
