Default 2006 ram 1500

just went and picked my truck up and the speedometer appears to be off by around 8 mph. I looked into the factory options and the dealership said it originally came with 17" rims. Now it has 20" . does anyone know a how or what to do about recalibration of the speedo?
please and thanks

Speedometer calibration is now an electronic function within the truck computer.

You can recalibrate for differing tire sizes using a programmer, such as a SuperChips or HyperTech unit. If you have a HEMI, I'd suggest a DiabloSport Predator.

One other option. Since Dodge now makes and sells trucks with 20" wheels and tires, they should have a flash for this in their StarScan tool. When I upgraded tires and wheels on a GM truck some years ago, the dealer was able to load a program that accounted for the larger size using their "ScanTool II" handheld programmer and code reader.

I'd check with the dealer service manager or service writer on the availability of a flash for your computer on this.
