Locally I have used Elite in the past but yesterday Etyres came out and were first class.
I got the guy to swap the fronts and rears over at the same time. And then asked him for some lead balancing weights too!
For 235/40/18 tyres they were £60 more expensive per tyre than Elite for Michelin Pilot Sport II but I just got some Dunlop's this time around to see how they go.
Got 54000 out of the MPSIIs on the front so will see how the new ones hold up!
