Used the 3d cruiser pan and sliced cake off and added icing to sculpt the shape. Tires are doughnuts (never again) covered in RBC. I had a small divider plate that had 4 clear plastic ligs that I put under the truck for stability then I had to add the styrofoam blocks between the tires and to hold the end of the truck up. I also put dowels in the front and back of the truck through the styro blocks. The tires looked perfect the first time i put them on. I ended up putting them on and off about 5 times
