5" Wheels

However, I warn that they're a pain to mount. That being said, they're fantastic wheels. Their driving surface is among my favorites.

Good Luck!

That's the first positive review of a banebots wheel I've ever read (for driving).

I would recommend Colson Performa wheels, they come in 5" sizes but provide less traction.

However, I would also recommend you work with a chassis design that allows for regularly available wheel sizes instead of restricted to 5". What is requiring a 5" wheel?

Mcmaster sells some nitrile rubber wheels that are 5 inches, but they are very heavy.

unless you go down to 4 inches, i dont think there is much of a performance gain between cots 5 inch wheels and cots 6 inch wheels.

Stogi and Adam-

Are you sure about the Colsons having less traction than a wedgetop/roughtop??


A member of our team did a ton of wheel traction testing as part of his capstone project...the results may surprise you guys.

Also during matches they tend to heat up. Making the rubber sticky and more traction. They also wear down pretty evenly.

WOAH! 5 inch wheels???!!! It's like the compactness of a 4 inch wheel, and the largeness of a 6 inch wheel! Amazing!

I googled 5 inch wheels, and found some good results.

If you're looking for a more customized wheel to suit your needs, and you have any crude lathing or milling abilities, you could consider making your own out of stock aluminum. Then you can make the diameter whatever you want, as well as customize other features like lightening pattern and how it fastens to sprockets and/or shafts.

Obviously, you should CAD the thing first, keeping in mind the limitations of whatever shop tools you have. Then, the actual machining process would be an excellent exercise for any student. We really need to give our students more jobs like this; they somehow can't ever drill a hole in the right spot, let alone mill something to spec.

Sorry if that was too unrelated to your inquest about buying wheels, but its an option that, while usually not as practical, shouldn't be totally ignored.

Where can these results be found?

That's very interesting, I'd like to see the results.

Let me get the results from our teammate, and I'll publish them and repost with the location.

Has this happened?

I too am interested. And, I'll throw in another vote for the Colsons, although they are a little heavy.

[Brandon Holley]

Embarrassingly no. We have a meeting tonight- hopefully I'll have time to pull the data off the computer while I'm there.

Colson rubber wheels heat up o.O

So what you're saying is that our robots should be doing side swerves in autonomous, like NASCAR racers do on pace laps?

Might be able to get away with spinning in circles for a few seconds at the end of auton.

The crowd always likes that.

Thanks. November is almost upon us, so it's time for my annual "what wheels might we want to consider" internal monologue.
