Yes that's true. I factor in the 6 to 8 percent offset any time I'm looking at my mileage. It's slightly annoying, but it would be very expensive to fix and I really enjoy the larger tires (gasp). I also have to realize that when my spedo says I'm going 60 I'm really going about 65.I hope you're not still running the same tire size. That size is over an inch in diameter larger than the stock size. You won't get an accurate reading with that size anyhow.
