Motorcycle Rim and Tire designed in SCAD with variables. I designed this to customize a 1:12 Yamaha Vmax-Model. But when playing with the variables you can use this for any bike and scale.
Perhaps a native englisch-speaker could help with the description of variables in englisch.
'bett' is half the tire-width in mm
'schr' is a value for the angle of the tire-side
'radi' is the radius of the tire outside in mm
' adur' ist the outer diameter
'high' is the thickness of the tire
'felg' is the thickness of the rim
'kard' ist the diameter of the inner part in mm
'kari' and 'kara' are offset values of the inner and outer side of the rim's inner part
'karr' is the inner corner radius
'speh' is the skoke width
'spei', 'spea', 'speb' and 'spec' define the spoke hole,
spei and spea are mm, spec and speb are multiples of 3°
'spez' ist the numer of spokes
