in my case,dunlop rep.i been told i can get 7 days on front and 4 on rear,so i was thinking thats pretty good for $ 320. i learn the hard way its not true.i got only one day out of my 211 Gp-A set at mid ohio.i got different setting now so i can get 2 days out of them now,so its still pretty expensive.they are awesome tires ,only bad think you get only couple dayson this.will see after i try 211-GP.
