Most rims will do just fine. You need to know the backspacing and diameter of the bolt circle. Check your tire rating and make sure the rim can handle the same load as the tire. That's usually not a problem. It's usually best to find one with the center hole the same size as your stock ones. That way the hub is taking some of the load instead of just the bolts. They just need to fit under the fenders and clear the hubs and brakes to be OK.
