Deviaton ODO meter

I noticed a deviation of the ODO meter (NOT the speed...).Actually, 1 mile on the ODO meter is in reality 1.0465 miles.I did the measurements more than once and always find the same deviation (between 4 and 5%).Is this normal? Is it because the tires have a higher pressure than what Toyota recommends?
