1:10 1.9" wheel tire "liner"

thingiverse

How do I explain this thing...? RC tires, such as the ones I bought from Aliexpress for my 3DSets.com Rancher, have a bead design that is supposed to be pinched between the rim (the outer lip) of the wheel and an insert that goes inside the tire. There's probably a word for this inside piece - leave me a message if you know what it is...I'm an RC noob. When the two halves of your wheel are assembled, the bead of the tire should tuck inside the insert and the rim squeezes against the insert to keep the tire from spinning on the wheel. The 3DSets wheel design is very nice, but lacks this feature. And it's very easy to add. This tire insert that I created is designed for wheels with 26 mm (1") between the rim on the front and back, measured from inside to inside.
