It is very important to pay attention to the country of origin, all of the above applies to Korean rubber. Before them, I had a Chinese-made hankook optimo - it's a complete horror, plastic bagels. Has some pros: Soft and at the same time very durable, easy to balance. At 150 like on rails, excellent road holding. Wide grooves cope with drainage in the rain. Several times I caught large pits and once a brick at about 70-80 km / h. Hernias did not appear and the discs did not cut them. (dimension R15 195x55, forged wheels) Cons: I have already caught 2 self-tapping screws, they are screwed in like butter, Kamov rubber would not even notice them. I drive with 2 harnesses, everything is fine, I didn’t even balance after that. Probably the disadvantages include low wear resistance, which would be logical. Mine is 2 years old and the low total mileage does not yet allow such a conclusion.
