Why radial tires are better

A second layer of a radial tire is made up of "plies" which consists of rubber-coated steel embedded into the rubber. The direction plies point makes a huge difference. In bias tires, the plies are diagonal, making the tires' walls less flexible and hindering performance. With radial tires, the plies start at the center and run radially from bead to bead around the tire.

That's why they're called radials and why they perform better. Although vehicle owners can still purchase bias tires, radial tires have proven to be much safer and more comfortable option.

Bias Ply vs. Radial Truck Tires The question of bias ply vs. All-season tires vs. Tire Construction and what it means to the driver Bias and radial tires are constructed differently, and they are manufactured with different materials.

Bias Tire Characteristics: Bias tires are less expensive than radial tires. Bias tires can carry heavy loads. Bias tires do fine when going in a straight line, but they do not perform well on curves. Bias tires are also susceptible to abrasion and heat because of the shape change. Radial Tire Characteristics: Radial tires provide a smoother, quieter ride. Radial tires track the pulling vehicle well, so there is better sway control on curves.

Radial tires run cooler because their steel mesh dissipates heat, which reduces the chance of a blowout and adds to the life of the tire.

Radial tires have a wider footprint, which spreads out tread wear and also adds to the life of the tire. Radial tires are more resistant to punctures.
