2011 Kia Sorento, 08 Toyota Tundra, 1956 VW Manx buggy, 1958 VW rail
I posted that I had put on a size bigger tire. my son says the extra weight of the tires will hurt gas mileage. i thought that it would slow the engine down a little and help gas mileage. we just drove from anaheim to pheniox driving 78 and 80mph and got 22mpg. we have gotten 24 and 25 at 70 to 72 so my v6 does not like the higher speeds. on the way back at 75 (TO GET BETTER MILEAGE) on flying J gas, my mileage dropped to 19 at Indio and finally to 20 at anaheim (DOWN HILL TO A LOWER ALTITUDE) Why did i lose mpg on the way home driving slower. (poor gas?) by the way-- why wasn't the 2011 V6 fwd included in the poor mpg kick back from KIA? thanks, sam.
