I just got new tires on my 2002 ll bean outback(this is when it seemed to start happening). I used to get 27-28 mpg on the highway and around
18-20 mpg in town. Now i am lucky to get 18 mpg on the highway and 14 in town. The tires are the same tires that were on the vehicle and the car has around 57000 miles on it. Any ideas why the sudden severe drop in mpg? Thanks,- posted
