This is just a preliminary, only 2,000 miles on them-(4) Continental Pure Contacts 215/55R17, 94V. I don’t have enough data on them yet. But right from when they were installed, my MPG dropped & stayed lower as compared to one year ago. Right now I am saying 2.5-3%. Driving habits or routes have not changed since car was new. Same 37 PSI in them-cold. Might not seem like a lot, but on a 48 MPG car in warm weather, that is over 1 MPG. I could have saved some money by going with the Goodyear FuelMaxs. The Pure Contacts (Safety) are rated better, especially in the snow (my main complaint with the Goodyears)-I’ll report on that & the ride in the Tires Technical Discussion when I have more experience on them.
