2006 V6 automatic coupe. 26 MPG highway. G019 tires, using the door jamb specs. 29 psi front, 32 psi rear.
Isn't this sorta crappy? Im doing like 60mph using cruise control. What tires do you reccomend for best gas milage and comfort? These tires i have now are utter shit to be honest.
Just curious: how do you know that you are getting 26 mpg highway?
I've found that some folks don't calculate their economy properly OR call different things "highway".
If you are interested in tires, I am VERY happy with my General Altmax HP's in terms of ride comfort, quiet, and hydroplane resistance. They perform very well in the twisty stuff, yet the ride is hugely improved over the OEM Michelins that came with the car.
According to fueleconomy.gov, your highway mpg is dead on with what they estimate you would achieve (which either means you are doing it right or this is where you got your highway number). Per that site, they estimate you should get 18 city and 26 highway (average of 21) with most people actually averaging 23.9.
If you want to improve mpg, keep the revs below 2500 rpm during acceleration, keep the car as empty as possible, keep your speed withing 5-7 mph of the speed limit, keep your eyes open, and try to predict traffic flow to avoid using your brakes and coming to a complete stop. Also, don't warm the car up for more than 30 seconds (ever) and don't idle while waiting to pick people up.
