Our team built custom wheels on our 2007 robot (which used 14 of them in the drive system). Personally, I don't recommend it due to the time it takes to manufacture and the weight of the resulting wheels in many cases.
These days it's easier to just buy some VexPro Traction wheels, they're more than durable enough and they weigh less too.
Now granted, this is based on what I know about my team. We've always had terrific manufacturing capabilities (a full machine shop at our disposal, with CNCs, Lathes, and more) but limited manufacturing manpower (we have more machines than we have people to run them). As a result, we try to prioritize making only the parts we absolutely have to, and use off the shelf products for everything else. If your team has the resources and manpower to build something like this and not have it slow down other parts of your build, go for it.
Sometimes you have to eat your vegetables, do your homework, and get some sleep. Otherwise you may get sick, have bad grades, and or fall asleep during the championship. - IKE [more]
