16" tires are no longer being made in a 245/45/16 size or even 265/45/16, however there are many still made in a 50 aspect ratio. If I bought a set of 265/50/16 is there a way to correct the speedometer to read faster? I know there is a sensor on the diff, mine is currently a 3.25lsd big case. What would happen if I took the sensor out of a 3.46 or 3.64? would it make the speedometer read faster or would I be able to correct the signal elsewhere. I appreciate the input.
Myself I would not be concerned, keep your eyes on the road/tach/temp gauge & the mirrors....and drive on. But there are specialty firms that do speedo repair and adjustments. I would bet there is a variable potential resistance screw on the cluster somewhere for factory setting. Problem would be setting up a bench situation to allow adjustment. Would be a pain to drive, pull cluster, adjust, drive again etc. Would be nice to know in case you get a speedo that is way off true reading. In your case....drive on.
