I have some e/t drag tires on some weld pro stars with rim screws. I'm wondering if you can go to a radial tire on those rims without any leaking or do I need to find a guy that can weld aluminum to fill the holes from the screws?
Why not tap it and put in some socket head screws in with thread sealer and if they protrude inside at all you can do some grinding, that way you can always go back to using screws if you wish?
