Hey guys, my wife and I bought a Mazda 6 with dealer installed aftermarket rims. Long story short, we recently found out that the rims have an incorrect offset that the dealer covered up by putting very low profile tires on (OEM is 215/50R17....dealer put 215/40R17). So I'm getting prepared for battle and I was currious if the offset is printed on the rim somewhere? Thanks.

 

On my last car, I put a set of aftermarket rims on it and they had the offset written on the inside of each rim.
