Was Vehicle Towed: - Description of the Complaints: The kuhmo ecsta supra 712 was a replacement set of tires on my l999 mustang gt convertible. the tire is designed to displace water through a large, lateral center channel. from reading descriptions of the tire, this tire design is intended to provide a high level of hydroplaning resistance. as an automotive association executive director with many, many years of operating high performance vehicles, i am truly concerned about this particular design. the tire seems to have signifcant lateral gripping capability both in wet and dry conditions. however, the deep, lateral center channel seems to make this tire unsafe for anything other than a perfectly smooth highway. this groove "grabs" any perfections in the roadway that are parallel to the actual road surface and will actually "snatch" the steering wheel from the grip of the driver. anything in the roadway such as "overpavings" which create parallel ridges, heavy truck traffic lane depressions in the road surface will do likewise. while not a design engineer, it appears that this groove down the center mimics a train wheel on the track. the train can only follow the track due to the track inself being inserted into the train wheel. any imperfection in the roadway that is parallel to the direction of the highway and the rotation of the tire creates a remarkably similar sensation. while i have not had an accident, i have nearly lost control of the vehicle on four occasions when the groove "gripped" any of the aforementioned road imperfections. i am 53 years old, a graduate of numerous decision driving and performance driving schools and am not an amateur in the realm of vehicle operations and dynamics. in all candor, these tires are scary and i will not let my teen daughter drive the car with the new tires.*ak (tiresize: 245/45z/17)( dot number: tire size: 245/45z/17 )
