I heard they are a good rain tire, but people have yet to know HOW good they are. I’m sure there are a few reviews floating around.
Here’s a little blurb:
The Direzza Sport Z1 Star Spec tread compound is molded into a directional design featuring notched, continuous shoulder ribs, large intermediate shoulder blocks and a wide center rib to deliver consistent contact with the road and enhance grip during cornering. Two wide, circumferential center grooves, wavy shoulder grooves and multiple lateral grooves provide water evacuation to enhance wet traction. The tire’s internal structure includes two wide steel belts reinforced by JointLess Band (JLB) Technology spirally wound polyamide to provide strength, uniform ride quality and high-speed capability while steel cord reinforced, 2-ply polyester sidewalls help resist lateral deflection to provide responsive handling and cornering stability.
