205/55/15 MPG - Toyota Yaris Forums

Tonavi · 01-27-2010, 11:22 PM

I just got new tires last week. Since I have aftermarket DXR wheels that are 6.5 inches wide, I moved up to 205 series tires from the OE 185s. I got between 40-45 MPG in the summertime with the 185s aired up to 40 PSI. I currently have the new tires (Yokohama Avid V4s) at 42 PSI and have a hard time breaking 33. I know it's winter and the cold is hard on everything, but to compare the stock tire size with the Yokos, how much of a mileage drop is reasonable? Will I be able to stay in the 40s? This last week it hasn't been especially cold, maybe -10, and I haven't broken 26 today on a route that gives me 40 in summer.
