8" Pnumatic Wheels @ Andymark soldout

[ghesla]

We are trying the HF 8"wheels, we removed the steel hub and used the 4 screw holes to make our 3D printed hub concentric. Probably we will be machining the hubs with some better plastic.

For what it's worth, the AndyMark 8" pneumatic hubs are back in stock now. We ordered them and then bought the wheels and tubes off Amazon. That should allow us to handle our business with minimal fuss. (Just make sure you buy tubes with right-angle connectors, per AndyMark.)

ALERT!
The AndyMark 8" hub assembly for the pneumatic wheels appears to be in stock!

We just spent the last week building custom hubs and a drivetrain with these same wheels. Watch out for the bearings. They don't seem... adequate. We're looking for other options still.

Yes, we removed the steel hub and the original bearings, they can't handle the range of RPM that we use in FRC... Thanks for the hint, anyway!

Would you mind me asking what you replaced them with? Does anything from AM fit these?

We have printed a hub with the 4 main holes of the wheel's plate, so we can hold it concentric, the hub have space for 2 flanged bearings and the holes for the sproket.
I don't know if i have explained it clearly, if you need more details PM me.

We've just ordered mountainboard tires from MBS.com once again. We already had their Rockstar Pro Hubs from 2011 and the great folks on the phone there said if we got our order in early enough today, they'd ship today. Note: there are local distributors but none are near us so I didn't bother with that option.

We loved the colors available on their T3 tires but opted to go with the Vine tires because of the increased traction.

Hope this helps other teams out there searching for a hub and wheel option.

We just ordered a single T3 wheel to try them out. How well do they fit on the AndyMark hubs?

Curious about this as well.

Just purchased 6 of the T3 in green and tubes. Was on the phone with Tim discussing the available options and all. Great service and provided a small discount.

We have two Vine's in house (and 16 more coming in tomorrow) they work great on the AndyMark Hubs and we have filled them up to around 70psi. I've heard MBS might be out of stock soon on the Vine's. If you look around you can find a wide variety of 200x50 tires, Razor makes a few scooters that use that size tire as well.

[electroken]

The same tire as sold by Andymark (except in black) is used on some smaller scooters and lawn equipment. If it is a Cheng Shin brand 200x50 and has the C-968 tread pattern it will be the same rounded profile, diamond treaded knobby many are still looking for. Our set came from a lawn equipment repair shop.

The black ones are NOT non-marking, meaning your robot will leave skid marks on the floor.

Thank You. Have some on the way to possibly try out.

These look to be similar to the wheels at Harbor Freight, but at the Canadian Equivalent Princess Auto, for teams that are interested. http://www.princessauto.com/en/detai...ly/A-p8442410e. The unfortunate thing is they don't come with a bolt circle to adapt a hub, and like the Harbor Freight wheels, the tire (2.8 x 2.5-4, whatever that means) does not appear to be compatible with the AndyMark hubs (200x50), but I would love to confirm.
