bought two falken 245-45-18z rated tires for my infiniti m35 my grouse is the first time buying and last of these tires . on the 95 doing 70 mph when the tire separated scared the hell out of me as the rear of the car started to slide into the next lane followed by uncontrolled vibration within the car. short of this is these tires being sold by your distributors are out dated and dangerous will never use falken tires or recommend them
