I do have 115 wheels on my cars, but have test fit several 4.5 wheels on my Bonne and you really cannot tell a difference between the 2...think 7/10 of one mm divided by 5 id the amount each will be off.....pretty insignifigant. How many people have clearcoat on there wheels peeling off, I think that would be as big if not a bigger thickness variation then 7/10 of one mm.
