Can cars have odd number of wheels?


assistant
Cars are vehicles that allow you to commute from one point to another. These are built by companies across the world and designed based on the companies choice, local context, historic reference. The car has three main parts: i) the engine that provides the thrust or power to the vehicle. ii) The body or the frame that provides the space to transport things and people. iii) The chasis which is the structural component that does the load bearing and has wheels which transfer the power of the engine into horizontal motion. 

Cars generally have four wheel but can sometime have odd numbered wheels as well. For example cars have a fifth wheel, the spare wheel, bolted to the body for differentiated look. It is not uncommon for cars to have a wheel stolen in which case they have three wheel. Few cooler car designs, modified cars, smaller cars can have three wheels as well but it is rare for a car to have zero or one wheel.
