The Tropics are reqions of the Earth which have a fairly uniform length of day throughout the year, and fairly uniform temperatures. There is no "Summer" or "Winter" as such - but there is often a "Wet" and a "Dry" season. This is all due to the fact that the Sun is never far from overhead throughout the year.
For convenience, the tropics are defined as places where the Sun is directly overhead at some time of the year.
If the Earth's axial tilt increased to 45 degrees, the length of day would change noticeably, and temperatures would vary significantly throughout the year, even for someone living directly on the equator (in fact, such a person would have 2 summers and 2 winters every year!).
Our current concept of "The Tropics" would be obsolete.
