Extremely cheap 6x2 tire with aluminum hubs!

Has anyone tried these pnuemies out?

They are 28 bucks each shipped with prime. An entire set of 4 would be 112 bucks. If anyone can design a pulley for these things it would change the overall price of trying to run pnuemies. It would be less than running abecs!

And yes, they use standard 608 bearings


These do use 608’s bu the hub is a lot wider. So, you would need to use extended axles.
