yoko

Does anyone know if the Yoko Advan Sport 255/30/19 extra load v103s has been discontinued? My tyre guy said he can only get them in z rated which cost more but hes still doing me a good deal

I noticed that the brand new C63 in my local dealers showroom has a full set of Yoko's on it. The rears on that should last approx 1000 miles before needing to be changed ! I have bridgestones on mine from the supplying dealer. What is the popular consensus on tyres for C63 ?
