1/43 Slot Car Tires from TPU

I printed these tires from TPU for replacements for some old Jeuof 1/43 French mad slot cars. They are not too bad, but a bit more firm then rubber or silicone... Great for drifting. I had to use my hair dryer to heat them to get them to go on the rim. There is a center well for the rim. They are about 5/8 O.D. 3/8 thick for the rear and 1/4 thick for the front. I.D. is about 1/4 inch with the well in the inside about 1/8 deeper or bigger ID at about 1/16 to 3/16 wide (don't remember)
