I've had several master models printed for resin casting, as said above just make sure the resolution (number of triangles the stl file is saved as) is high enough and you specify a high-detail material for printing.
I've had wheel inserts done, tires and complete bodyshells 
Here's the idea

3D data


And here's the reality, all parts done from 3D masters, including the wheels and tires for the pickup

For the 3D files I either bought it or created it myself, then uploaded it and did the usual route for silicon mold and resin casts. The tires are urethane, what doesn't come across in the photos is the tread pattern and sidewall letters I could do!
