Understanding Automotive Tire Repairs

What is the primary difference between radial and bias-ply tires?

• Radial tires have steel belts running at a 90-degree angle to the tread.

• Bias-ply tires have steel belts running at a 90-degree angle to the tread.

• Radial tires are made entirely of rubber.

• Bias-ply tires are made entirely of rubber.
