What are bias ply tires good for?
Because there are a uniform number of plies to support the weight of a vehicle in both the tread face and the sidewall, bias ply tires are generally better when hauling heavy loads. This is why trailer tires, tractor tires, and heavy equipment tires are often bias ply; they can better support heavy loads.
