Review on 🚗 Hypertech 752504 Speedometer Calibrator: Enhancing Speedometer Accuracy and Performance by Matthew Wheeler

This tire gauge worked great on my 2019 Ram 1500 Limited (new body). My only tip to save you time is to actually measure your tire from bottom to top. tires and use this measurement when entering the tire size. I spent some time just entering the tire size on the side and my speedo still didn't work as a result. With the help of a Hypertech support rep, he quickly explained to me that some tire manufacturers cheat and round up tire sizes, and also explained how to measure them. After measuring and entering the correct tire size, my speedometer didn't work, using two different phones and a speedometer app to confirm.
