Our second robot used 8 inch plastic lawnmower wheels (Home Depot @ about $10 per wheel). We just drilled 3 holes and mounted the sprocket using 1/4-20 bolts and spacers. That robot just went through it's third build and those wheels still have tread on them. Even being run on asphalt several times. We've also used wheelchair casters when we needed something very light and have moved up to go-kart wheels last year.
