I am trying to model a motorcycle tire and rim as learning project.  I have been able to convert and wheel blank DWG drawing to a 3d object and

guessestmated a tire but still need more help.

Is it better to use the revolved base/boss or the sweep base/boss to draw the rim and tire?

How do i move the front,top and right planes to my drawing centerline? do I need to do that?

Should I move the orgin to a point on the wheel centerline? How do I do that?

When I try to letter the side of tire I cant seem to select the side wall I can letter on one of the planes but the the lettering is not on the side wall.

I atttached the drawing if you want to look at it.

The rim blank is a 17x6.5 for a 190 tire

Were can i get a drawing or cutaway of a motorcycle tire?

thanks

john
