what kind of wheels are those?

[@Lindz37]

Hi, so the origional ones are longboard wheels "Knuckle Heads 75mm 78R. the new ones are "urethane Wheels - Cast Centre" I believe they were designed for lifting equiptment. The place I got them don't sell them anymore but if you want a look at the place I got them see the link below (they came with berings in them too). Cheers.
