PNEUMATIC TIRE AND PROCES FOR MANUFACTURING THE TIRE |
摘要 |
A pneumatic tire includes a carcass structure, tread band, belt structure, and sidewalls. The carcass structure includes at least one carcass ply and at least one annular reinforcing structure associated with the at least one carcass ply. The tread band includes first and second sectors. The first sectors are axially spaced apart from each other and tapered along a radially inner direction. The second sectors are axially spaced apart from each other and tapered along a radially outer direction. The first and second sectors are disposed axially side-by-side, one after the other, along a transverse development of the tread band. A ratio of Shore A hardness at 23° C. of the elastomeric material of the first sectors to Shore A hardness at 23° C. of the elastomeric material of the second sectors is greater than 1.10:1. A process for manufacturing the tire is also disclosed.
