Tire Sidewall problems of the 2000 Mercedes Benz ML320

Both front and rear passenger side tires easily suffered sidewall cuts by a tree branch; w/ no pro-rata warranty applied to new tires purchased because national tire and battery said sidewall damage is not covered under general's warranty - tires should not split with normal driving at 10 mph and no previous accidents or mishaps affecting the tire - also when pavement is wet back end loses traction for a second and car slides sideways and I'm not sure if it is the tires or the vehicle - but I am concerned these tires could prove dangerous at normal highway speeds.
