If it's a truck tire shop, you probably won't have any problems. Some of the "Farm & Garden" centers, etc. won't touch a split ring wheel of any kind. Find an oldtime truck tire shop with people who won't panic at the idea of a tube-type wheel & tire assembly. Some of the youngsters out there don't have any real tire experience.
