tire size change=mph change?

I recently upsized my tires from the stock bfg rugged trail 265-70-17 to some Toyo open country AT 285-75-17's, Does anyone know how much of a change it will make to the speedometer reading the current speed. I can't imagine it being too much different but if so what is the easiest way to have the speedometer corrected to read the acurate speed. I do not have a Smarty, nor know anyone that does. Thanks in advance for any help on the matter.
