I was having some new tires put on all the way around. I was just told there are some rust holes on the rims. I have read about rebuilding these wheels. Is it better to rebuild or buy new wheels. I would prefer to keep the dollars as low as possible. This is not a show car and is being restored by my 17 year old son and not a show car. Can the holes be welded closed without compromising integrity of the wheels? Thanks for the help.
