265/65/17 to 265/70/17

I tried searching for the answer, but did not find it. Can you adjust the computer for bigger tire size?? I was looking at the goodyear futura triple treads. The don't come in the stock size only 265/70/17's. I want the mph,mpg and odometer to be accurate. I know it would be only a little off with the larger tire size.

I think you may be able to find answer in some previous threads using the search. From what I've read, there is no easy way to do this adjustment. I think the conclusion that it would be complicated and expensive. I believe there is info that one member has provided about the change to expect -- pretty exacting if I recall. It basically boils down to a under-report of your speed 1-2% (from memory) and same on the odometer.
