i did germany in june and the french alps 2 weeks ago and one day in the alps it was 31 deg the following was 3 deg with snow on the cols and these tyres performed ok, they dont like over banding but than again ive had other tyres that dont as well ie pilot rds, id say ive done roughly 4k and there is no real wear sign and no squaring off from motorway runs to and fro home and ferry's infact the rear has a nice even wear from shoulder-shoulder, so i recon there is loads of miles left in them at least 8k + and this is the first ive had one set of tyres do 2 trips as its usaully 1 set 1 trip, now only thing i dont like about em is the feedback its not as good as other tyres im used to ie dunlop sportsmart(these are like glue and good wet weather as well).
So they get thumbs up from me however i did run mine at 34f/36r and a tyre rep on the trip with us said i should run 36/42 !!
