[quote=tamumpower1]Those are the same ones I use. If they don' hold air then drill a big hole in the sidewall of the tire and fill it with 2 part post hole foam from home depot. I think it took about 2 bags per wheel for mine. It's not super cheap but way better than the cost of new wheels. You can put an 18 on them without the cradles but it's going to eventually put a dent in the hulls. Short term you'll survive but at a minimum put a few wraps of old carpet around the rollers. That will help a lot.
I made some cradles for mine but that would take more time than you have.[/quote]
