I have a2021 ram1500 classic had a 6” lift and it has 35x12.50R20lt tires on it. My speed odometer is off what’s the best tire programmer to use to celebrate the speed odometer. I’m new to this stuff so want some thing easy to use lol.

The cheapest and easiest way to do is to get the OBDJScan app for your apple or android phone and a supported bluetooth OBD scan tool and change it yourself. The app charges $20 for a license to make changes to one VIN. The bluetooth OBD scan tool on Amazon is less than $50. Now you can change the tire size as well as many other parameters for far cheaper than those plug and play devices. I forgot you will also need a bypass module from amazon too for fairly cheap.

Here is a thread with more information: SPEEDO PROGRAMER
