From the Super Mario Wiki
The Triforce Tires (known as Triforce Tyres in PAL regions) are a set of tires included in The Legend of Zelda × Mario Kart 8 downloadable content pack for Mario Kart 8. As the name implies, the tires are emblazoned with an icon of the Triforce from the The Legend of Zelda series. They share the same stat changes as the Slim and Crimson Slim tires, slightly increasing speed and handling, while reducing acceleration and traction.
The Triforce Tires were shown off with an image of Link riding the Master Cycle, but were not announced.
Stat values are out of 6.
