3D Printing is pretty neat. I have done a few pieces for model car tires and wheels. I modeled these full scale then I scale them down for 1/24th, 1/16th, 1/12th, etc. here are some screen shots of the models and actual parts I have in hand.
These are 275/40-17 and 345/35-18 Pro-Touring style tires.

The printed tires.

The black ones are a cheaper material. The clear ones are Ultra detail frosted ABS. The detail, even this small, is incredible!
