A Fat Tire is when you are with a fat bitch and instead of banging her in her pussy you do her in her bellybutton. This may or may not be intentional; sometimes she is just too fat and you just can't find the right hole, but there are occasions that you knowingly stick it in her bellybutton because it feels good or you are too embarrassed to stick it in her pussy.

The first documented instance of this act taking place occurred on April 6, 2009 at John Barleycorn's pub in Schaumburg IL.
There was no way in hell I was going to bang her so I gave her a Fat Tire instead.
