My son have Exost 360 tornado RC car. One tire of the car has a hole due to some spiky vegetation. I tried to repair it but nothing works. I haven't found any replace part for this car model. So I designed one. 

Tire Surface is not the same as original, I choosed a simpler one for ease of conception and good printability. For better traction result, consider using TPU.

Freecad file is included so you can modify it at your whish.
