Changing Speedometer Gearing?

Is there a relatively easy way to change the speedometer gearing? Recently changed to a smaller tire size and it is way off.

Thanks

Paul

What year truck? 88-95 requires changing the drac module or resoldering. 96+ Will require a programmer or a tune.

It's a 97. Got an incredible deal on tires and rims.
