tires and miles

if i have 32 inch bfg all terrains would that affect how many miles it says im traveling. i already know im about 2-3 mph faster than what the speedometer says but will it affect my odometer reading?

Yes. For every hour you drive, your odometer will read 2-3 miles less than you actually travel. So if you actually travel 50 miles in one hour, your odometer will say you travelled 47-48 miles in that hour.
