Part Tire Function

# Function Overview
Name: Tire Function
Function: marks the part as a tire
From FVTM: yes

The TireFunction defines a Part as TIRE.
If using the BasicSystem for vehicles, every wheel slot needs a not just
a part with a wheel function, but also a part with the tire function.
Note that a part can have both tire and wheel function at once,
so old wheel parts can be converted easily!
The actual size and other values of the tire you have to setup
in the Part - Tire Installation Handler!

Example config:

{
    "__comment": "Part JSON file.",
    "Function": "fvtm:tire"
}
