I modeled the Marui Big Bear tire as close of it I could make it...
When looking to print it I scratched my head :

• no way to print it without supports, and supports in TPU are quite are not going to help
• the tire is big, so no way it enters in my resin printer for flex resin printing

I finally decided to cut the tire in halves, and print them by halves in TPU (picture is 95A shore, but it should really be printed in lwer shore 50A to 65A). I built internal rings to avoid the need for supports during printer, and it will remove the hassle to add an internal ring inside the tire before mounting it onto the rim...

You need the two connecthalves parts to align the halves together when gluing them...

Please note that I did not have a chance to get my hands on Big Bear tires, and this was modeled based on measurement provided by a friend who needed tires for his Big Bear...

Enjoy!
