Patent abstract

Pneumatic tires for service on heavy vehicles having a belt package with widened belts. The tire includes a belt reinforcing structure or belt package having multiple cut belts of which one of the cut belts has a width approximately equal to the tire footprint. Widening two of the cut belts and forming at least one of the widened cut belts from a lighter material serves to improve tire durability in the regions of the tire crown and shoulder without increasing the overall tire weight.
