Slick

The Slick tires are a set of unlockable tires in Mario Kart 7, Mario Kart 8, and Mario Kart 8 Deluxe. They resemble  P Zero tires, which (except for the wets) are also s.

Mario Kart 7
In Mario Kart 7, the Slick tires offer the strongest speed boost (tied with the Gold Tires), while also offering a small weight boost. Their acceleration is hindered slightly, but their handling and off-road are hindered heavily, and their handling is tied with the Monster, Red Monster, and Gold Tires for being the weakest handling among all the kart parts. They are also tied with the Gold Tires for having the worst off-road boost in the game.

In terms of hidden stats, the Slick tires excel very poorly while underwater, but they're also one of the very few tires that boost speed, but do not have a negative impact on air handling.

When compared to the Gold Tires, the Slick tires are slightly lighter and have much worse sea handling, but have better air handling and acceleration. Also, unlike the Gold Tires, which hinder drifting, the Slick tires boost drifting positively, making them pretty useful for tracks with extremely sharp turns.

Mario Kart 8 / Mario Kart 8 Deluxe
The Slick tires return in Mario Kart 8 and Mario Kart 8 Deluxe as unlockable tires, with their appearance being altered to an extent. Their statistics are also different in that they no longer have a negative impact on handling in any terrain, and don't boost speed as much as they did in Mario Kart 7. However, the Slick tires still have one of the worst water speed stats in the game along with the Wood tires, but their water handling has been improved to make up for it. They're also the fastest tires while on any of the anti-gravity portions of a track and their air speed has been increased as well. But their traction stat is the worst in the game.

The Slick tires also have a variant called the Cyber Slick, sharing the same stats as them.

In Mario Kart 8 Deluxe, the Slick tires still share their stats with the Cyber Slick tires and their water speed has been slightly improved, though the air speed is significantly worse. The acceleration, handling, traction and mini-turbo stats have also been further worsened. The Slick tires still have the worst traction stat, and have the lowest stat total out of all tires in the game. CPU Luigi uses these tires with the Circuit Special.

Mario Kart Tour
The Slick tires return in Mario Kart Tour, used by the Circuit Special, Black Circuit, Green Circuit and Carrot Kart. Red versions are used by the Blue Soda, light green versions are used by the Dark Trickster, and pink versions are used by the Wild Pink.
