Re: How does oversize tires affect mph?
whoa, i just got all confused. we put 285s on the 2500 in place of the sissy-girl stock 245s. our speedo was way off. the speedometer read 45mph, but the truck was actually going 49-51mph. then on the freeway, the speedo reads 70mph, and the truck's going 75-77mph.
