Contact patch is the portion of a vehicle's tire that is in actual contact with the road surface. It is most commonly used in the discussion of pneumatic tires, (i.e. pressurized tires), where the term is strictly used to describe the portion of the tire’s tread that touches the road surface. The term “footprint” is used almost synonymously.
The following discussion only applies to pneumatic tires.

“Yet for all that, there is nothing in me of a founder of a religion—religions are affairs of the rabble; I find it necessary to wash my hands after I have come into contact with religious people.”

And bearded bronze, but not a man,
Although I patch him as I can
And reach through him almost to man.”
