Yes, if you change to larger tires your braking distance will probably increase. But since your just changing tires, I doubt it will change too much. Now if you are increasing wheel size also, then definately your braking distances will increase. This is due, simply put, to the increased weight of the wheel and tire. As far as stopping ability vehicle aside, unless your running a mud type tire (usually wide seperation between lugs for self cleaning) there shouldn't be any difference there.
