We ordered (and received) a good size order from these guys on very quick turn around.

I recommend them highly. Their price is far lower than everyone else as well.

The tires are not what's pictured. What you will receive is a black version of the AM tire (anodized black for superior performance!).

Yes

They are Cheng Shin 200x50 tires. AndyMark's 8" wheel is the same tire.

AndyMark doesn't make the wheel itself, he bought an existing one so many other supplier have the same tire.

I do recommend using Andy's hub though, we bought a bunch and are very happy with them.

Posted seconds after 10 of these tires arrived on our door step.

Thanks for sharing though. You've guilted me into doing the same!

To be honest I'm kind of excited to see all the different wheels people use this year and get their suppliers for future notes... I think the community will discover some very cool stuff this year.

Agreed. It never occurred to me before this year that the 200x50 size was a standard one in the industry.

We ordered a load of these, which are currently stinking up my car until the hubs arrive tomorrow/Monday/whenever we thaw out:

Edit: Looks like Amazon's got a third-party seller (http://www.amazon.com/Rotary-10428-Cheng-Shin-Knobby/dp/B00CNUGJIM/ref=sr_1_4?rps=1&ie=UTF8&qid=1453434392&sr=8-4&keywords=200x50&refinements=p_85%3A2470955011) selling the same tire Adam linked to in the OP, albeit at $15 shipped instead of $6.99 plus $6.99 flat shipping. From being an FBA seller myself, that "In stock on 1/24" message means they have the items and are transferring them between warehouses.

FYI, the grey versions of the Cheng Shin 200x50 tires are non-marring, while the black ones are not. Be aware of where you drive those tires.

I had to Google what non-marring meant and still am not sure what it means in relation to tires. In laments terms? The gray tires won't leave marks and the black ones might?

That's the difference. The black ones leave skid marks. It's why "boat shoes" have white bottoms.

I've found that FRC is leaving a trail of destruction on 200x50 tube/tire suppliers. A found a couple other potential sources when we were looking, only when I looked again the next day they were both sold out. Heck, even our local harbor freight had its 8" pneumatic wheels picked over.

Which is fine for practice bots, spares, etc...

We just received 12 of these (http://www.mobilityequip.com/after-market-group-111002-pneumatic-tire-8x2-inch-200x50mm-light-grey-tread-c9210-35-psi) yesterday.
It has more of a street tire tread on it.
They mounted up perfectly on the AM hubs.

I just tried to order these, as they still showed in stock. I used chat support to check on shipping time, but when he checked he said they were actually already out of stock, the website had not been updated. In his words:
Actually, I am sorry to inform that this item is currently in back order with the manufacturer due to the Robotics competition. We normally have plenty of these in stock but they flew off the shelf over the past couple of weeks. Our supplier is the manufacturer itself and they will not have this product either until approximately mid February.

I agree with Sean, any small inventory most of these suppliers had seems to be wiped out by FRC teams. All are stuck with MFR lead time of 4-6 weeks.

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!

Nice colors!

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

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?

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.

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.

When they said "your killing me" they meant it in a good way.

This is definitely good for all of these companies. Although I'm sure all of them wish they had more.
