I just bought some 18x8 ASAs for my car. I have koni struts with eibach springs on my car and am trying to figure out what tires will fit with out rolling the fenders. I am thinking 235/40/18s all around will fit and I am not staggering the tire sizes because I dont want to change my current handling while going from DSIs. Anyone got any ideas for me?

Offset?

a 235/40 should be ok depending ont he drop.

I am pretty sure its a +44mm offset. Is there an easy way to measure this to make sure?
