I just replaced my 2019 Touring Hybrid Accord with Michelin Defender 2. Immediately thereafter my mileage decreased dramatically--with each fillip I had about 509 miles to drive; now it's only about 430. Has anyone else had a similar experience? Does anyone know what the original tires were (I stupidly did not write it down). I have had them for less than two months and do not want to continue to drive the vehicle with the dramatically reduced fuel economy.
