Anyone from TireRack, please offer your expertise on the following questions. Thanks.

For the square setup of 225's all around, how much wider can the stock wheels handle? 235, 245?

For the Msport, and 19" staggered setup, how much wider on front and rear? Same 235, 245 on front?
And 265, 275 in rear?

Is there enough room?

On my 135i I have a staggered 225/255 setup. I went with 235/265 with all seasons with plenty of room for the tires on the wheels and wheel wells.
But, I think 235 up front is the limit with most tires as wider tires would rub.

Once I get my 335i Msport, I'll need new tires within a couple months.
It will have the staggered sizes. I'll be getting high perf. all seasons like Conti DWS, or Mich Pilot Sports.
I'm running Conti DWS on my 135i now. Great tires btw.
