Someone help me with this. I have 15" rallye wheels which are mismatched 2 won't balance, I am trying to figure out if they're small or big bolt pattern so I can get some new wheels. When I measure the distance between the studs with the wheel removed I get a measurement of 4" from the center of the studs. On the wheels when I measure the distance between the the top of one bolt and the middle of the diaganol hole I get 4.25". I did not think a 15" small bolt pattern rallye wheel was made, so I am confused by these measurements. If someone knows the correct measurement between the studs of the big and small bolt pattern please post it for me. I appreciate your help
