Speedometer Calibration

Speedometer Calibration
I am new to this site and new to Ford ownership. I recently bought a 1998 F-150 with the 4.2L. It has different tires than factory on it so the speedo is off. I've read some posts about using the odometer and inputing a code but mine has an analog odometer so that is not an option.
Is there any way to calibrate the speedo to reflect the differnt tires?
Thank you.

Dude, get a chip from motorhaven from Ken. www.motorhaven.com
Go to the Diablo chip for Fords section. They are $230 shipped to your door. It will totally fix the speedo AND give you some power to turn those big wheels to boot!

What size tires are you running now, and what were the original size tires.
Here's a link that will tell you how much your speedo is really off.

If all you care about is fixing your speedo then just get a "Superlift Truspeed" speedo calibrator.
It's infinately adjustable and can be self adjusted a million times, every time you change gearing or your tire size. I'm probably going to get one since I keep changing gears and tire sizes. Look here.
