Abstract
A radial-ply tire has a tread provided with at least one block isolated by longitudinal and transverse grooves. A central wavy sipe and a peripheral wavy sipe are disposed on the block, each of the wavy sipes running zigzag along a centerline, wherein the central wavy sipe makes a smaller angle with the centerline therefore than the peripheral wavy sipe with the centerline therefore.

A radial-ply tire having an equatorial plane and a tread provided with longitudinal and transverse grooves thereon comprising:
- a block isolated by the longitudinal and transverse grooves on the tread;
- and
- a central wavy sipe and a peripheral wavy sipe disposed in a central region and a peripheral region of the block, respectively, with respect to a circumferential direction of the tire, each of the wavy sipes running zigzag along a centerline, wherein the centerlines for the central and peripheral wavy sipes extend in parallel to each other and substantially transversely relative to said equatorial plane and the central wavy sipe makes a smaller angle with the centerline therefor than the peripheral wavy sipe with the centerline therefor.
