I have read other posts regarding tires and I need new ones, again. I have the Primacy tire on it now. After only 11k miles, they need to be replaced. I read someone recommended the Pirelli P4. I did not like the Primacy's, in rain I felt jerking for correction in the tires and huge hydroplaning when the tread was down only a little. I'm in Tennessee and when it rains, it can be intense. I also have problems in the worn grooves on the interstate. Any tires suggestions?
