How correct is the speedometer?
i just put 33's on my truck along with heavier steel wheels. Does anyone know how much the speedometer is off by with 33's and if reads faster or slower than the actual speed?
it depends on what size tires came on the truck from the factory mine says it came with 235/70r16 and it now has 285/75r16
so at 65 on the speedo im doing 73 and at 70 im doing 80

I agree with SOME of that...my truck came with 265/75's and 3:73 gears so it didn't effect me as much as it can others.
