We've been looking into using 4" wheels so we can get our CoG lower. Not sure about using WCD though. I'm not sure if these are the 4" hi-grips

if these were 3" wheels, we'd try them on our Octocanum. 1/2" hex with no need for a special hub? Yeah, I'd look at them over Colsons any day.

Well, 4" wheels are the limit for COTS wheels in FTC, so they may very well be aimed towards that market. Plus it gives a CoF for FTC foam tiles.

Does it seem as though they could be used in a drivetrain?

Are the tread on these wheels similar to bane bot wheels or that of Colsons? In other words do these look usable for a drivebase, before I buy a pair to test them?

The tread is the same as the hi-grip Tread material.

It says it is TPU, but it doesn't give a durometer rating.

Durometer is 77A on both. http://www.andymark.com/Rubber-Treaded-Wheels-s/220.htm

*face palm*

Didn't even notice that

[Pratik Kunapuli]

They do have the coefficient of friction listed for carpet as well as the FTC soft tiles so I assume they were marketing this to both FRC and FTC.

[DiehardCybercard]

The pictures were just updated for the Stealth wheels. There are now pictures of that display the integrated hub for both wheels.

[MetalJacket]

I seem to remember reading that the KoP chassis will have a direct-driven center wheel this year - does this sound familiar to anyone else? If that is correct, then these could be the wheels for the 2014 KoP

[geomapguy]

Yeah and it's going to be sheet metal. This must mean that the field won't have bump-like obstacles???

So the Toughbox Mini with 4 inch wheels?

We're getting the PDV. Anyone know when we'll get it??

I'm having trouble imagining why you'd want to bolt a gear or sprocket to these wheels. What am I missing?

The only circumstance that'd make driving an attached sprocket useful is if you're driving a completely different type of wheel elsewhere. How often does that happen?

Maybe there's a dead-axle hub on its way?
