New AndyMark Wheels

Has anyone seen these wheels before

I think they might be geared toward FTC but maybe they could also be used for FRC.

Any thoughts?

Haven't seen or heard of them--but I do know that a number of FRC teams use 4" wheels as their go-to size. Most folks go with 6" wheels, or 8" wheels, but there are a few that go 4". I want to say most of the ones that do are using a modified WCD.

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.

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

3'' or 2'' versions of these would be greatly appreciated, yeah. Price-wise, these look like they'd blow Colsons out of the water.

They come in 1/2" hex, and 8mm key bore, so my hunch is they're intended for FRC.

They look like they could be used as a drive wheel, with a respectable amount of grip if their number is correct. Colson(ish) looks.

I ordered two to try out, you'll never convince me to not run nitrile roughtop for high traction setups.

They are VERY light for their size for such a durable looking wheel, so I'm interested in them for rollers, etc...

I'll post when we get ours.
