Hey Peter,
You won't have problems with that size and offset, as long as your not running super hektic low....
You may get a slight rub on full lock when the car is on an uneven surface but wouldn't worry about it too much. Try to keep the tyre width under 285, it will reduce the rubbing also.
As far as the tyres rubbing whilst driving you won't have a problem, again as long as the car is not lowered too much....
Cheers
