I guess brand new tyres are much grippier than well worn ones, hence slight mpg reduction perhaps
I'm going by the mpg figure the car is giving on my weekly 320 mile round trip. I reset it each time and it always shows 48mpg but this week it's dropped to 42 after having these tyres fitted.
3 days doesn't give you much time to calculate fuel consumption? Unless you're doing a few tanks a day! ;)

Had these fitted to mine 3 days ago. Fuel consumption is much worse! It has dropped from 49 to 42mpg! Anybody else find the same?
