So if my over size tires are 4.5% taller then I should be around 67 mpg? If this is the case I will be absolutely delighted.  |
The math doesn't add up to 67mpg. I'm at 68mpg for my tank, at half a tank and at 407 miles so far. If you were only 1mpg behind me at 4.5% you should be somewhere around 360-380 miles on your trip (plus 4.5% means it would be +~20 miles, equaling 380-400 miles). I have pretty fresh Re92's so my odo should be within 1-2%.
[Edit]: I didn't see you said you were 'almost' at half a tank. Keep an eye on your gas gauge, if it hits half between 360 and 380 miles you are probably around 67mpg. Just remember you would be 73-76 with Re92's.
