You can put a wider tire on just watch your chain/sproket clearance. You also need to allow about 1/4 inch extra as the will swell with heat and speed.

Short Answer: A 15x6x6 will fit and give a bit extra clearance. Some people say that the caliper will rub but the fix seems to be a bit of localized grinding to clear some room.
Hope that helps.
