The "trim ring" part of the 7" type is about twice as deep as that of the 6" type. You can tell the difference 30' away, so if your 20 covers all look pretty much the same, they are.BTW, what is the dimension of a 14x7 Mach I sport wheel cover when you lay it flat on a table? I have about 20 wheel covers, but I am thinking now that they are all for the 6" rim.
This is the 7" type. Very deep.
