Gold Tires

The Gold Tires (known as the Gold Wheels in British English versions) are a set of tires in the Mario Kart series. They are gold versions of the Standard tires. CPUs never use the Gold Tires, along with the Gold Standard, and the Gold Glider, making these tires player-exclusive.

Mario Kart 7
In Mario Kart 7, the Gold Tires are unlocked by collecting 15,000 coins, or getting at least a one star ranking in all of the GP cups for every engine class. They offer roughly the same stat boosts as the Slick tires, and they offer the best speed boost, but they also offer the worst off-road boost. However, the Gold Tires give up some more acceleration to enhance weight. Additionally, they're tied with the Slick, Monster, and Red Monster, for the weakest handling boost in the game.

In terms of their hidden stats, the Gold Tires have a negative impact on sea speed, but interestingly, they don't affect the sea handling stat. They also hinder the air handling stat, making it more difficult to steer while using the glider. And unlike the Slick tires, the drift stat is hindered. Based on stat totals alone, the Gold Tires have the lowest stat total of all the tires in the game.

When the Gold Tires are combined with the Gold Standard body and Gold Glider, they complete the whole Gold Standard. This kart gives great speed (the 2nd biggest boost in the game) and good weight, but has a bad handling boost, and abysmal off-road (the smallest boost in the game, which is on par to if the Slick tires were used).

Mario Kart 8 / Mario Kart 8 Deluxe
The Gold Tires also appear in Mario Kart 8, along with the other gold parts from Mario Kart 7. They look slightly different than they do in Mario Kart 7, however.

In Mario Kart 8, the Gold Tires' stats have been altered to be more balanced, boosting ground speed and weight, while hindering acceleration and traction. In terms of their hidden stats, the air speed and anti-gravity speed stats receive a boost, while the water speed and mini-turbo stats are hindered. The Gold Tires share their stats with the Metal tires. The player can unlock the Gold Tires by beating all the non-DLC Staff Ghosts in Time Trial mode.

In Mario Kart 8 Deluxe, the Gold Tires' stats are much less balanced than in Mario Kart 8, only boosting ground speed and weight. All the other stats (except water speed) are hindered, with acceleration being hindered the most. The Gold Tires still share their stats with the Metal tires. The player can unlock the Gold Tires by beating all 48 Staff Ghosts in the 150cc Time Trial mode.

Mario Kart Tour
The Gold Tires seen in Mario Kart 8 and Mario Kart 8 Deluxe reappear in Mario Kart Tour used by the Gold Snow Skimmer and the Gold Standard, the latger being exclusive to Coin Rush. The Gold Blooper, Gold Cheep Charger, and Gold Pipe Frame use a gold variant of the Pipe Frame's tires.
