I would disagree with the generalisation that energy saving tyres have less grip.
My past experience of Michelin Energies in the late 90s – yes. Horrible tyres.
But my winter tyres are Nokain WRG2 which I bought for the grip but they are also a low rolling resistance tyre and give me better mpg than my summer tyres so I expect their summer low resistance tyres would be even better for mpg and more suited to the summer (winter tyres get a bit squishy).
Speaking to other people about other mainstream makes I believe that their energy saving tyres have come a long way.
I would take a look at MyTyres for starters and see how much something like Uniroyal, Vredestein, Avon, Nokian and Goodyear are. Michelin will cost you a lot. I have some Kuhmo Ecsta sport on the back of the estate and they are working well. Have some Vredestein Sportrac 3’s to go on though but I like to drive hard.
What is your tyre size?
