Well, I upgraded to the Goodyear ComfortTred 195/60/15 last Friday. Staring with a full tank, I drove to the northside of Detroit yesterday and back today for a total of 241 miles. Most of the miles were at 65 mph plus. Got home and put 4.15 gallons in the car (even after adding a little more after the pump stopped - I know I shouldn't) I didn't verify it but had Goodyear bring the tires to 40/38 psi (F/R). This comes out to be 58 mpg :lol: - if I take into account the different tire size with a actually distance of 238, I still end up with 57.5 mpg. I know this was a first test, but... I am driving to my inlaws in Zion, IL (north of Chicago) Thursday and coming back on Sunday for about 700 miles altogether. It will be interesting see what I get then.
