I would think that the trip computer would be dead on accurate as far as calculating mileage. I have different tires than stock but they are the same size (225/45/17). The area was quite flat as well.
Are mile markers accurate? 10% seems too high in terms of inaccuracy.

225/45/17 is not stock size. Stock is 215/45/17.
