Rally Wheel Cover Issue

You didn't say what bolt pattern you have.
SBP use 7/16 studs and 3/4" across flats nuts.
LBP use 1/2" studs and normally 3/4" AF nuts. BUT, there are 13/16" nuts out there that require a larger diameter socket and that might be your problem.

Sorry, I have a large bolt pattern.

I’d have to check the size of the nuts to be totally sure if I’m running 3/4 or 13/16.
