Most highway rims look alike, but all vary somewhat in certain construction features. Variances between rims of different types make part mixing hazardous. A close, proper fit between rim parts is essential to long tire life as well as operating safety.

Although side rings, flanges, and lock rings of different types appear to be properly seated, difficult to detect gaps are often present.The illustrations in Figure 3.10 show correct, safe matchings of rim parts. Mismatched rings and bases, which almost always create an unsafe operating condition are also shown.
