Also, are you at 40+ psi?

I would give that a shot if I didn't already have a pile of extra 225/60/16s. 4 mpg is a lot for a relatively simple change!
I have the tire pressure up to 44 PSI which is the sidewall max rating. I haven't seen any increased wear in the center of the tire. There is some other weird wear but that is because the steering system needs overhauled. I'm afraid to go higher for reliability reasons. I drive around 60 miles a day and the tires are getting old
