Size: 245/45ZR17, ZR rated Y speed rated. Took the first drive on them, there was a horrendous drone noise over all speeds. Excessive harmonics at 50 – 55mph, and again at 70-75 mph; so loud it's difficult to hear the radio. Tire needs redesign. Harsh ride due to thicker sidewalls and reinforce bead buildup (creating low tire compliance). Source of noise: Tread shoulder too wide, sipes and grooves on shoulder too wide and rounded, shoulder blocking grooves are normal to the direction of travel leading to tread blocks slapping the pavement. Resolve this noise by angling shoulder grooving between tread blocks. Overall Poor tire due to noise.
