This tire was really the only Michelin option since the Weatherwise tire is no longer an option. Have observed a decrease of about 5 MPG. I asked the sales rep about other reports of decreased gas mileage and was convened it was a mistake...it was not. We have consistently gotten 28 MPG for the past 250000 miles on our car and we are down to about 23 MPG.
These tires are significantly louder than the Weatherwise tires but that was expected with the stiffer rubber compound used to get 90000.
Wish there was another Michelin option for this tire size.
