One of our mentors who gave us some history of the traction materials said that out of all materials wedgetop and roughtop were great for the carpet but wore out super easy; and while designing the wheel we wanted it to have great traction/grip on the carpet, easy thread replacement, cost efficent and YELLOW.
So far we haven't had to swap out threads our threads from last year are still good they just don't seem to wear out; im assuming these are good as wedge/roughtops/Nitrile but very long lasting
Do you possibly have a picture on hand that we could see?

Dang it! haha. :D

The Thread is Made up of 70A Polyurethane.
We got Polyurethane Tubing of 4" OD x 3"ID 70A Polyurethane and cut it to 1" slices. Then cut the ID to 3.25" and make a .125" wide cut for the Lip of the rim to rest on.

So it's like a colson tread, but one piece? Sweeeeeet.
We're totally going to try that come summer.

well there is Variety of Colson threads; the most common ones have a higher durometer which means the thread is pretty hard. We used 70A because it was right in the middle of Soft and hard + Grippy

Great to hear that You'll be trying it out!
Let us know how it goes :)

That's pretty neat. How is the tread kept from spinning around the wheel? Friction?

Here is our 2014 version of our 3D printed wheels. We integrated the tread from vex pro.

We were fairly happy with them. They are made on a uprint plus, ABS solid.

We would get two pairs on a print in about 10 hours.
We basically used the same profile from VexPro CAD and built a wheel around that.

The tread is held with friction and compression; We compress the tread slightly onto one rim and then sandwich the other rim on top just like a "sandwich" or "oreo".

As mentioned by Eric this material is polyurethane 70A. The nice thing about ordering polyurethane is it comes in several colors. One factor that was key to selecting this material is that the material for our wheel had to survive our 2+ mile walk in the parade.

Here's an image of a complete wheel.

That hub looks heavy. What is the weight of one singular wheel? (including tread)

How well did it look after the parade?

I like the idea of not having to continuously replace the wheel for demos and such.

Team841 Purchases it's Polyurethane from Sunray-inc.com
Colors are on their Website
