tires on fwd car

Daughter ran a wire through the sidewall so, I am assuming two tiers will need to be replaced. Do you think the new tires should go up front or the rear..I have always heard both sides.

 

Front.

 

Tire manufacturers (and distributors, and installers) recommend 4 new tires, or, barring that, 2 new tires going to the rear. That way you have the tires with the deepest tread providing the most traction for the rear, which keeps the tail end of the car from floating around when cornering during crappy weather.
Conventional wisdom says to put the best tires up front, where the engine is, but it's not correct. The weight of the engine and transmission in a front wheel drive car provide added traction, even for tires that are partially worn. Putting partially worn tires on the rear means that the tires on the back have a tendency to "float" through snow or slush, which in turn tends to make the rear end slide back and forth while cornering or braking.

New tires go on the back.
