There are not split rim rims on an early Packard, they are LOCK RING rims. Split rims are two piece rims, that are bolted together, and used almost exclusively on construction equipment. Also a 100 lbs per sq in. truck tire, is a different animal than a 40 lb 1930's car tire. That said there are dangers if not handled properly as outlined in earlier posts above. I would not take these to any local tire store where some 16 yr old is changing tires. Yes a truck tire facility is still the best option, however many of us have done these tire changes without incident for years. One important factor to consider is the type of tire being used here. 1930's cars require 1930's type tires made for lock ring rim installation. The tire bead is the most important aspect of this. One tire still produced is the Firestone Balloon tire, which I am told are made in the original molds from the 1930's. These tires mold around the lock ring as the tire is inflated putting pressure on the lock ring and forcing it into the ring groove. People make a big mistake installing the wrong tire and that a major mistake with these cars, no radials here. Also check to make sure the ring has not lost its set. The ring should fit the groove and snap in tight when installed, I have seen many rings that have lost their tension and should not be used.
