Speedo calibration tools

[cj7]

Are there any speedo calibration tools for a 20 1500 that let you enter revs per mile?

Revs per mile?

Yeah, most tires have a published spec that indicates how many revs it will turn per mile when on the vehicle under typical load. For example, the stock 275/55r20 Alenza H/T turn 651 revs per mile. It’s a easier way than size to make the speedo calibration.

but maybe that’s asking too much...

I believe that the ones available use tire size in 1/4" increments as the variable. IDK for sure since I don't own one, but I'm sure others will chime in.
