Include all details.

I have a 2020 250
Default tire circumference was 2631
I was able to get it to take 2800
I have the nitto ridge grapplers 37x11xr20 measure to 36”

This worked for me also. I was a few km/h off when putting in 2395 for my 255/55/19 tires but once I changed it to 2315 using this formula it's been bang on.

I enter 1870 and then its worked

Hi team - LOVE the site.

Making it quick - 2023 F350 6.7L HO Lifted and new tires and rims from stock to 37 X 13.5 x R22.
Speedo is off +8Km/h actual or (108) at 100Km/h indicated on dash
I did spend the time to READ the @zoodad (Rock star) threads and have tried to walk my way through the process however I keep getting the wrench and engine light when I change the Tire Circumference in the BDY module (English).

Original setting from factory = 2631

I looked to find the setting for my tire size and have tried 2941 but then realized many people are saying that is way too high, so I went to others who tried 2770, 2780.

I do the PCM TCM reset and clear DTC codes and still get Wrench etc.

Being a very JR user, get a bit scared to mess something up I put back to 2631, do the PCM TCM RESET (as there is no RELEARN) and Clear DTC's and it is fine.

I do not have "RELEARN" only RESET for PCM TCM - see attached. I have tried 2746,2770,2780,2799,2800. I'm positive there is a step I am missing,

Is there a number that has worked for similar and maybe 2023 is different? - @willyfly4food - did you change any other settings or just the tire circumference in the Bdy CM ?

Happy to take suggestions or advice from someone with same settings on same year?
Thanks!

Can you please explain why the number .967 was applied. Ie. What is the significance of this number specifically. Many thanks

I'm ready to pop my new tires, help!!!!!

I put on a set of 315/70r17's, largest on the size selection list, and went to adjust it in the BCM and it will not change it on my dash. I do not have a TCM but did the relearn of the PCM and still nothing. I started with 265/60r18 then changed the wheels and tires, now I'm off 5-6 mph. Anyone have any suggestions? TIA

Thank you for the detailed instructions. I am working on a 2024 F550 with 305/70/R20 tires. I performed the BCM tire circumference adjust and the PCM, TCM and AWD module vehicle data relearns. I did not receive the message "tire circumference parameter is out of range for this module" in any of the 3 modules. The AWD and TCM complete successfully but the PCM dues not. It reads "Service procedure has been interrupted" at the end of the relearn. I attempted the relearns of the 3 modules in varying orders. I now only have the code P160A:00-2F in the TCM, even though it's relearn completes properly. Any ideals? Thanks for your time.

Hi,
We own a Transit V363 / 2022 and it is 5% off in Speed against GPS.
I have tried to change the values in BCM and in PCM and did the relearn in PCM.
TCM relearn doesn‘t work. I contacted support about it and they mentioned it is not supported / needed for my car.

Regardless what value I store in BCMii, the 5% doesn‘t change.

Any help is welcome
