Improved safety against aquaplaning.
Wide tread grooves displace more water and optimise the tyre's contact area with the road - for greater safety in wet conditions.
Improved handling on wet surfaces.
The special rain tyre compound increases the effective grip on the road; large, rigid shoulder blocks reduce deformation when cornering. These two combined improves handling, especially when cornering on wet roads. See the full description of the Uniroyal Ms Plus 77
