265 Bfg's

[Radon]

I just bought 265/75/R16 BFG A/T's and I love them but I was wondering where can I get my speedo recalibrated along with the odometer (duh). A lot of cops partol the area and I know the difference is not much from the 255's I was running I just to tie up all the loose ends. Thanks guys. BTW I drive a 2000 2wd if that has any bearing on the topic.

I just stepped up from 245's to 265's and had my recalibration done at the dealer yesterday on my 2000 Silverado ECSB 4x4. I had asked them to update the PCM and the ABS computer and at the same time update the BCM for the factory foglight kit I put in. It came to $99.95. Another option, if you go with a wait4me tune etc. they can update the tire size when you order it.

Go to this site and enter in the original tire size and then the new tire size. It'll give you the differences in the two size tires as well as compute the % difference in the speedometer (at the bottom).

You could adjust your driving accordingly until you have the computer reflashed.

I went from 245/75/16 to 265/75/16 and the difference was like only 2mph. I drove like for a year and half until i went to a local repair shop that had a master tech software that programmed the computer for me. 50 bucks.

That's about right, as I was quoted the fog lights would be $40. (and paid 99.95 for the tire changes + fog lights). I wasn't so much worried about the speedo as I was the ABS system. I wanted it updated for Anti-lock purposes.
