Great source for 8" Pneumatic Tire to match AndyMark

[s_forbes]

We found that most tires used for mountain-boarding are the 200x50 size that fits on the andymark hub. These ones are a bit of a tighter fit than the original gray rubber tires, but they did seat properly.

MBS T3 tires.

Stylish, too!

Awesome to see the MBS T3 tires fit well. We're expecting our batch of them on Monday (perhaps later due to snow delaying shipping).

Any tips/tricks involved with mounting them to the hubs, or was it painless?

Nice colors!

But I just watched the only remaining option, black, go from "Available" to "Sold out" before my very eyes.

Assemble the tire/tube/hub and bolt the hub together, put some soapy water around the bead to let it slide on better, and then inflate. Like I mentioned, it is a tighter fit... we needed air pressure to force the bead all the way onto the rim.

When we get around to assembling all of our wheels, we'll probably install the six bolts that attach our aluminum hubs to the AM wheel before inflating. I'm not sure how much I trust the little screws around the perimeter of the wheel.

I had an amusing conversation with one tire supplier. It started with him saying, "Who are you people? You're killing me". He normally sells 20 200x50 tire in a week. He sold several hundred on January 11th.

You'd think suppliers would be happy with an influx of orders, unless they're losing money on them or something.

Where are people on the east coast planning on getting their 8" Colson wheels?

Yeah the salesperson at MFGsupply was really curious about what caused them to sell out their entire stock in a matter of hours. (Gave her the link to the game reveal video).

I think this thread had an impact on their bottom line this month

RobotMarketplace (Florida) has Colsons in stock (as well as various companies that mount hubs or sprockets into Colsons)

YMMV with the speed they turnaround orders (or their responsiveness to inquiries about back-ordered items). Generally they're relatively quick, but it was like pulling teeth for us last year trying to get them to ship us our order in a timely fashion(the WCP hubs were back-ordered, and we simply wanted them to ship us the rest of the order).

We have a bunch on the way. With exchange, not cheap, though. Stay tuned for a photo of them on our custom built hubs. We cut some side plates on the waterjet we have access to. The waterjet hex hole is a perfect fit. Thanks, Sheridan College!

The term is actually non-marking which of course is self explanatory. The primary application of the non-marking versions are on personal mobility scooters where they will drive across floors you don't want to leave black marks on.

We have been using the MBS vines so far this season and haven't run into any problems.

Has anyone found a source for the 1" - 4-40 thread rolling screws that come with the AndyMark hubs? We have tried using regular 4-40s and they don't work well in new hubs. Trying to avoid having to tap all the hubs.

The guy at MBS that I spoke to asked what sort of robotics competition is this and said something like "that is so intense" when I directed him to the reveal video. I told him to look for a local tournament since it is free for spectators to attend. Maybe someone in the Colorado Springs area can go make a presentation to them and ask them to become a sponsor.
