Speedometer Question

I have a 97 F350 C/C 4X4 longbed with the 7.3 psd. The factory tire size is 235/85/16. I wanted bigger tires, therefore I went with the BFG LT315/75/16. I know it has thrown my Speedo off. What is the easiest way to fix this, without having to go back to factory size tires?

Thanks

Dont know if they can do this in your case or not. When I bought my 2006, I asked about if the speedo can be corrected when i get bigger tires. The dealer said it can be corrected. They would have to change things in the computer to adjust for this, the cost would be around $80.

Another option is a Superlift TruSpeed speedometer re-calibrator.

Computer should be able to be reflashed at the dealer.
