Pneumatic Wheels
 

Team 449 is building a new robot cart and needs pneumatic tires. Does anyone know where to get reasonably priced pneumatic tires that we can attach a #35 sprocket? We are aiming for an 8'' diameter, 2-3'' width.

Thanks in advance.

Skyway (a former supplier to FIRST Robotics) has several pneumatic and soft non-pneumatic wheels that might work:

I'm pretty sure Pink has used pneumatic tires for a while, you could also ask them..unless those are custom made

I've seen places like Northern Tool offer tons of pneumatic wheels in that kind of size range, but I don't think I've seen any that are particularly sprocket-friendly. I'd play with them and figure out whether you can do something with them before shelling out the dough.

Pink had custom hubs for there pneumatic wheels in 06 those things were awesome looking. Many places have pneumatic tires like the ones u described harbor fright is one as well as the others listed.

Team RUSH has run pneumatic wheels in the past. I don't know the exact supplier, but the products were for electric scooters, had aluminum rims and were available with sprockets that bolted directly to the hub.

Search a little for scooter wheels and I'm sure you'll find something. Check out this URL, tey have some similar items.

Northern Tool has the part you want for $15 per tire: http://tinyurl.com/6f7hzj

The wheels have a solid internal frame that can be modified to accept an Andymark wheel hub and bearing for use in your team's new cart.

Harbor Freight carries several styles too. You may have to weld your sprocket on.
