Ok, So Michelin are running an offer if you buy two specified Michelin tyres they will send you a £50 fuel card. So basically £50 cashback.
I have seen these
MICHELIN PRIMACY HP 225/45ZR17
For £98 each
or
MICHELIN PILOT SPORT PS3 91Y 225/45R17
For £101 (Concerned these maybe like F1 Super Softs and will last me 1-2k?)
Making it effectively £75 per tyre?
Forms and details here.

Not sure if it is a good ish deal?
Should also be ok to buy from Costo.
And blackcircles etc... Most places are fine, check with Michilin
