So I throw in the 205-70-13 for my Pontiac Phoenix and the 205-55-16 my Grand Am and Cavalier take, and find Overall Diameter 24.29 in and 24.87 in. I am paying a premium for tires with a bigger hole in them. A rip off just like the cartridge filter element you pay a premium for a filter with no base plate, shell, ABDV, or bypass.
