I think this is the best option for direct driving from a CIM

"Looking at the specs of our current robot, I come across a coefficient of friction of 1.067, which should be physically impossible. I have a hard time believing this, although such a feat could be accomplished on a carpet. But still, the robot accelerates at a seemingly impossible rate, running 2 CIMs on each side, and we are loving this "omnipotent" traction."
Excellent service, reasonable price, fast shipment. I couldn't ask for better service.

very good
FRC Team #1519, Mechanical Mayhem, used the 4" HiGrip Wheels on our 2014 Robot for our 8WD. We played 63 official matches this year, without any failures of the wheels or reasons to complain about them. The grip on the wheels is excellent, with manageable wear. We'd be game to use these again in the future!

Very nice wheels, good grip and tread.
What can I say, it is a wheel. We have not broken it yet
The AM14U is excellent straight out of the box with no modifications. I hope it performs similarly during the regional competitions.
Too many years of top notch service and product from AndyMark
"The 4 inch wheels worked well in conjunction with the 6 inch high grip wheels for are ball retriever (the 24 inch exercise ball for the FIRST 2014 game)."

To utilize these wheels with FTC/Tetrix, a custom adapter needs to be created. I would suggest AndyMark could sell a lot more of them if an adapter was also available. Other caution is the tread pattern is of fairly high durometer material and has square edges. These edges could damage the foam tiles used in FTC competitions. Radius-ing the tread edges in the mold would solve the problem.

"Okay - I took them to task for not having an adapter but they did add an adapter after we bought ours. Good move!!"
Great grip!
