Wheel is an installable performance-enhancing component for Extreme Gears. Its actual appearance is unknown, though it is presented as an icon on the head-up display in the top-left corner of the game screen. Its icon is a yellow-colored circle with a black Wheel type Extreme Gear inscribed in it.
In the game, Wheel is permanently installed into only certain Extreme Gears. When used, Wheel changes the Extreme Gear physically into a Wheel type Extreme Gear and gives it the same traits of a Wheel type. This allows the player to smash through obstacles and barricades by driving into them without slowing down, while gaining Gravity Points for each obstacle destroyed. Additionally, Wheel also lets the player use Slide Turn, allowing the player to make sharp turns without Gravity Control. However, it cannot perform Gravity Control to the full extent of most of the other Gear types.
In gameplay, Wheel and its ability will be disabled when starting a new race. To activate Wheel, the player must press one of the following buttons after collecting a certain number of Rings:
Wii (remote) - sideways

When activating Wheel, the player's Rings will be reduced accordingly by the number needed to enable it and the Extreme Gear is surrounded by an orange void, indicating that the Gear Part's ability is in effect. The following Extreme Gears come equipped with the Wheel:
