I purchased this tire based upon test results. Tire Rack has always provided great tests, no other tire store that I know of provides this service. They really liked this tire because it gripped like a Summer tire, but was an all-season tire.
Well, the grip is really good. But the tire has two big faults.
1. Tire squeal! This tire squeals loudly way before it starts to lose traction. I can be well under control and people around will look to see who is about to have an accident. The tire grips very well, but complains loudly while doing it. I cannot get anywhere near the limit of this tire without drawing huge amounts of attention to myself.
2. This tire is one of the worst tires I have had with regards to steering responsiveness. This tire is so slow to respond that the car feels like I'm driving a boat. I will admit that I have just come off some of the best tires I have ever had (Bridgestone RE01, this tire was the most responsive tire I have ever had on my SHO. The Bridgestone made my car handle like a Porsche). These Kumos have such a soft sidewall. The response from the sidewall is almost 1/2 second late. Breaking is fantastic, and the tire is hard to spin on takeoff, but turn in is slower than my grandmother! I am having to buy a new tire because I miss judged the response time of this tire and hit a curb and cut a gash into the sidewall. I have been traveling this road for 12 years and this is the first time I have ever hit that curb! Not a happy camper!
