 +Wheels are geometric shapes at a given position ''​R0'',​ with a ''​Radius''​ and ''​Width''​ all in meters, the ''​RimRadius''​ is the inner radius of the wheel, where the rubber stops (the rim), also in meters.
 +The ''​Inflation''​ is the pressure of the tire in pascals.
 +K and D are factors that define the strength of the forces generated per meter below ground and meter per second relative velocity respectively.

 +Main collision part, uses the mesh of the ''​Geometry''​ from the 3D model to compute collisions with the ground. The coefficients are optional lines of code that can be used to fine tune the friction of the part when skidding across the ground (kinetic) or when stopped (static).
 +Setting ''​CrashOnContact''​ to false allows the part to contact the ground without an taking damage. This is typically desired for the fuselage to allow the flight to continue after a tailstrikes or a gear up landing and also on the engine cowlings and (lower) wings, when the aircraft lands with gear up or the wing tip just briefly contacts the ground. Parts that contact the ground only in upset attitudes like the vertical stabilizer or upper wings in case of a biplane should always cause a crash on contact.
