What is the difference between a radial and a conventional tire?
"A radial tire with a 0°-steel belt is produced using the most up-to-date technology. These tires are suitable for higher speed assuring stability, light handling and sporty performances. A conventional tire is built according to the traditional technology. These tires are particularly suitable for off road applications and lower speed for their high tear resistance."
