Default 245 fronts and 275 rears?

I was wondering if anyone ran 245 fronts and 275 rears on stock 2009 is350 18 in. rims. I have coilovers on and was wondering if I had to roll the fenders to fit these tires.
Or is there a better set up with wider tires then 225/255 that i won't have to roll my fenders.

I've run 245's on stock front wheels (17's though), so that should be fine. Perhaps someone else can answer about 275's in the rear, but I would think they should be fine, the rear has quite a bit of room.

I'm running 245 front 275 rear. These are not on stock rims. They are on 18x8.5 with 40mm offset in the front, 18x9.5 45mm offset rear. They will rub if you go too low in the front.
That width on the rear is too wide for the stock rims. Or at least they exceed the recommended max for the 8.5" width. 9" rim is recommended. I can't tell you what the risk is of cornering too hard might be though if you have a rim a little too narrow.
