Tire (spelled Tyre in the UK-based Rareware games) are commonplace objects in a few titles of the Donkey Kong franchise, the first being Donkey Kong Country. Tires have bouncy properties that enable the Kongs to reach items or higher areas.
Donkey Kong Country / Donkey Kong Land
In Donkey Kong Country, there are two types of tires: round and half. Donkey Kong and Diddy Kong can move round tires, though halves of tires cannot be moved due to them being stuck in the ground. Halves of tires often appear on floating platforms. The level Bouncy Bonanza features the bouncing mechanic through, and as such, it features many bouncing many tires, both whole and half. Sometimes a tire is needed to enter inside a Bonus Barrel. Winky the Frog has a high bouncing ability that can be considered as roughly bounce about as high as when the Kongs bounce from a tire.
Tires reappear in Donkey Kong Land where their functionality remains unchanged. Both games feature a hazardous, spike-covered tire obstacle, Mincers. In early stages of development, tires were considered to be used for a much larger variety of uses throughout the game.
Donkey Kong Country 2: Diddy's Kong Quest
In Donkey Kong Country 2: Diddy's Kong Quest there are much larger tires resembling those from a tractor. They only appear in the level Jungle Jinx and retain the functionality of tires from their previous appearance. Due to their size, the tires can be hazardous, if one lands on the Kongs, crushes them into a wall, or pushes them into an obstacle such as spikes or pitfall.
Donkey Kong Country Returns
Donkey Kong Country (television series)
DK: King of Swing / DK: Jungle Climber
Round tires reappear throughout DK: King of Swing, where they appear floating in midair. They often act as obstacles because they bounce Donkey Kong back if he hits into one. Tires otherwise retain their general purpose from Donkey Kong Country.
In DK: Jungle Climber tires are featured in numerous color variants.
