Hi
I could seriously recomend Dunlop Roadsmarts
I was persuaded to use avons but when I went to Dunlop I realised what I was missing.
Qualifiers and Qualifier RR are great but only last 4,000miles.
The roadsmart grips better as for how long they last I would have to check my Friendly garage (TPG in Brighton).
I have to admit they did let go in the snow on a side street.
