2011 GMC Acadia fuel mileage problems

Asked by J May 01, 2019 at 07:11 AM about the 2011 GMC Acadia SLT-2 AWD

Question type: Maintenance & Repair

I have a 2011 GMC acadia that I put new tires on.  
Before tires I was averaging 17.4 mpg now I am
averaging 14.5 mpg.  I have replaced air filter, plugs  
and coils.  Oil change is recent also. No check
engine light and no other obvious issues.  Anyone
have any idea on what the problem could be?

Check your tire's air pressure and vehicle's fuel source.

Given your description of new tires followed by a reduction in fuel economy I'd assume that the wrong size tires were either put on your car or were on your car prior to the new ones being put on. I'm not sure how exactly the car's computer calculates mileage but I know that, for example, a larger tire will take the car further for each rotation and the opposite is true for a smaller tire. Maybe that could mess with the computer's mpg calculations. Just a thought...
