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 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.
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.
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:
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.
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.
