Colson wheel tread material?

I was wondering if anybody knew what kind of material the tread on colsons is made of. The standard gray ones you get from vex and such.
We found that it’s extremely grippy on the totes and cans and wanted to apply it.
Thank you!

I’m in my car right meow on my phone, but if you go to the Colson site they have a very detailed breakdown of the wheels. You could possibly find a equivalent rubber through McMasterCarr. If not, just buy a bunch of wheels, they are cheap enough :wink:

From the VEX website (at the bottom of this page)

Tread: 65 Shore A Thermoplastic elastomer Tread

I saw that, but that’s just the type of rubber I think, not the specific make (like ABS vs. PVC) because McMaster does not list that. Do you think any 65 Shore rubber will work here?
