at first i had stock tires then i changed them to 245/ 50/16. after that for some reason i had speeometer problems and the guy from the dealer told me it was because of improper wheel size, so then he programmed it to the corect size but it didnt do anything because the computer didnt recognize the new sizes. so now I have the stock tires back on and I still have speedometer problems, it reads like 5-10 miles faster then im really going. What should i program my tire size with the power programmer if i have stock tires now but the computer is thinking i have 245/50's
