That's very interesting, does this not therefore mean that they are subjected to four times more wear & then 4 times less life??The 255/45/18 has a slightly lower radius than a 235/55/17 meaning that it turns 4 times more per mile.
Nothing that accounts for high wear rate though.
Typical price difference between a 17" and a 18" Dunlop is £26 more per tyre for the 18" plus fitting etc.
