These are sand, snow, or mud tires for the traxxas stampede. they work great and due to the honeycomb like structure inside they do not ballon like the original traxxas tire. they should work on the slash and rustler with some modification to the body of the car but I have not tested them. the tires should be printed out or TPU and with 15% infill and 2 wall layers. they should also be printed with the face up and one at a time. the rims should be printer out of PETG and with 30% infill. the entire hub section should be printed with 100% infill to prevent the tires from breaking off of the axle. the outside face or the rims should be facing up when printing. I know that it will take a little longer and will use more supports, but this will make the outside face of the rim look much better.
