8" Pnumatic Wheels @ Andymark soldout
 

With the pnumatic wheels at Andymark sold out, and giving a couple week lead time does anybody else know of a supplier of a decent replacement?

Re: 8" Pnumatic Wheels @ Andymark soldout
 

But ... they came back in stock this morning.

Edit: Apparently I can't see big red blocks of text.

From the AndyMark website:

"AVAILABILITY NOTE (UPDATED 1/11/16):
Currently, this wheel is in high demand. We had many in stock and we are receiving another supply of tires within two weeks. We are accepting orders for these tires although we may run out of stock soon. Therefore, even though you can purchase this product, it may not ship until 1/22 or 1/25. We apologize for the delay. Please check here for the latest availability info before calling our office. "

It sounds like they have either run out or are going to run out very soon. They are still allowing people to place orders, but are saying there's a chance your order won't ship until 1/22 or 1/25.

What do you mean by 'decent replacement'? There are plenty of suppliers if you can create your own hub.

Re: 8" Pnumatic Wheels @ Andymark soldout
 

The Andymark 8" Cheng Shin tire is commonly used on mobility scooters and should be available from many sources. The hubs sold as part of the wheel assembly are single source, from Andymark.

You didn't catch the 10" pneumatic wheels on sale at Harbor freight this weekend? I picked up six of them, $4 each. They require hub work, as mentioned. But they might only be needed at the front of the robot, so we need to get busy prototyping and see what we can come up with.

Re: 8" Pnumatic Wheels @ Andymark soldout
 

what are you planning on doing with those steel hubs?
How much do each of them weigh?

Re: 8" Pnumatic Wheels @ Andymark soldout
 

They're heavy. The steel hubs have a tube on one side, I think it's 1-3/8" id. I was pondering whether we could weld a small steel hub onto the tube, and bolt a common robot sprocket to the hub. Or maybe press a longer tube into the existing tube. Or see how they work as unpowered wheels, going over the defenses. It's all conjecture at this early stage.

I know this is an AndyMark thread, but we have these available:

We will have pictures of hubs up today along with a full wheels assembled. Also we currently are 1/6 of our total "inventory" sold and have a decent amount of diamond tread available & zigzag tread available.

Re: 8" Pnumatic Wheels @ Andymark soldout
 

those look like a viable option as well
Got any idea what the durometer rating of the tread is?

Re: 8" Pnumatic Wheels @ Andymark soldout
 

Off hand I do not, If I'd have to guess somewhere around 60-75 ish. I'll email our supplier and find out and post the info here/to our site.

Re: 8" Pnumatic Wheels @ Andymark soldout
 

looking on the web for tires there seems to be lots of choices.
It's the hubs that will get you.

Re: 8" Pnumatic Wheels @ Andymark soldout
 

If any team looking for these AndyMark tires are near these locations:

Atlanta/Greater Marietta
Northest Ohio/Mayfield Heights

Those 2 Microcenters each claim to have a box containing 2 of these.
Please put them on 18 minute pickup before you try to pick them up to be sure they really are in inventory.
They will likely be on clearance.

Ahem - there were more of them - :yikes: SOMEONE:yikes: - put the rest in my barn.

Re: 8" Pnumatic Wheels @ Andymark soldout
 

I was looking at these yesterday for our team, but decided to go with the Andymark wheels for two reasons.
1. I knew they had stock
2. They were easier for sprocket mounting

I suggest you update your website to show these as in stock. I would also confirm whether these could be used with your wheels:

Hi Derek,

We will show these in stock once they are kitted & ready to go. We also updated the site with lead times so customers can see when they will be shipping. Let me double check today, I have an AndyMark hub handy and will get back to you. I believe that those hubs work with our Tires + Tubes for customers who want dead axle, those will be an excellent choice.

The hubs we sell are specially designed for VersaChassis like setups and/or live axle drivetrains.
