When you triple the weight of the rotation mass aka wheels your braking distance will double.When you use bigger rims and or tires you have to regear it to match the tire height to keep the rpms down so less stress on the engine and trans.And lets not forget the speedo will be way off if its not done.I'm a off road guy when you put huge off road tires on a truck is the same as 24s or bigger on a car the size of rim don't matter its the over all total height of the tire matters.I have proved this to a friend he put 26s on his caprice and kept telling me it made the car slower and harder on gas once he had it regeared it drove like it did before.
