I have a 2021 ram 1500 with the 3.6 pentastar V6 E-Torque. I put new tires on which originals were 275-65-R18
I put on 285-65-R18, a new flowmaster 40 series, and a k&n air filter( not cold air intake and cone) and my mileage is like 17.6 now from around 25. Can anyone give me some pointers on If this is causing it or what else I should maybe look into. No warranty anymore so trying to figure it out before paying dealer prices for diagnostics and such.
