Slang for an emergency T-type spare-wheel for a vehicle. These types of spare wheels are not very wide. Usually a torus-like tire affixed to a steel rim. They vaguely resemble the delicacy of the same name.

Not to be confused with a spare, stock wheel. (As normally seen on Jeeps and large SUV type vehicles.) Stock Spares are frequently attached to the rear door (on an SUV). Donuts are a feature of some cars, and are store in a small space in the trunk.

Donuts are very limited in their ruggedness. You can't go above fifty, and can't go over bumps or anything interesting on the road.
"I tore the balancer of my alloy rim, now i'm stuck on the donut for a week until the replacement wheel comes."
