I need rims for snows and there's a pretty good local deal on a set of four 19" 9.5" wide/+45 mm offset Konigs. I'm pretty sure this size will fit on the back of my IS-F, but have no clue about the front. I used an online offset calculator that suggests there would be 19 mm LESS inner clearance than the stock 8"/45 mm offset front wheels and that the outer edge of the wheel would extend 19 mm beyond stock. I'm less worried about the outer edge than the inner clearance - in particular, with that much less inner clearance, is there going to be tire rub while turning?

I know the best way to find out is to actually mount them, but before I arrange that, I thought I'd post here to see if I should even bother. All responses much appreciated.
