Having a larger centre bore won't break your studs. If you buy your winter wheels from Canadian Tire or Wal-Mart, then they are lug-centric. Haven't heard of a broken stud yet. The clamping force produces enough friction between the wheel and the hub to keep it in place.
Vibrations from lug-centric wheels are usually caused by not properly torquing the nuts, or by torquing with too much weight already on the wheels. We have four (had five) cars all on lug-centric winter wheels and none of them have vibration due to wheel fitment. Two of the cars have slight sidewall variations that cause a small vibration, but I know it is not due to the wheels because I mount my own tires and swapped wheels - the vibration moved with the tire.
