Perfect video for my 2022 F350 Dually 6.7 Powerstroke Lariat. Only difference is I don't have an AWD module to relearn. Can't thank you enough for posting this...Toyo Open Country AT3 35 x 12.5 x 17 @ 2647 to perfect Speedo reading...

Thank you so much for this video. Even the ford dealership couldn’t get my check engine light off after a year but with your help and forscan my tire size is changed without the wrench or engine light. 2022 f250 also doesn’t have the awd module. Thanks again

thanks for the great video, worked perfect on my 2022 6.7 with 37/13.5/22s went from approx. 7 mph over to being spot on (note to other users no AWD module on this truck)

Thanks for the video, TPMS adjusted just fine for me after driving for about a mile!

Great work got it done step by step 23 F250 Super with Carli 2.5 and 37s

Thank you so much. Success on a 2023 7.3. For anyone wondering there are no relearn module for the TCM, but everything cleared and worked without that step. Also, on the first re-learn process my truck had to be on first. Again, 7.3 gas. Forscan version v2.3.57

Wow. Great tutorial bud. I have done a few ForScan mods on my trucks but never was able to figure the tire size one out. Thanks for sharing. I am new Sub for sure.

This video was perfect for my 23 Superduty. Changed to 37s Toyo AT3s, and 2799 is spot on to 75. 80mph is maybe .5 off. Everything in the video was exactly the same as Rocky said it would be. Thank you, Sir!

This is so valuable. Thank you!

Hey Rocky, thanks so much for posting this video! Just about to try it on my 2023 F-150 EcoBoost 1/2 ton. Might not be exactly the same, but I'd imagine it'll be similar. Anyway, thanks for sharing.

Really informative! Worked a treat on my 2021 f250. Didn’t have the Awd module though . Thank you!!

Worked on my 21 tremor.. thank you

On a 2024 Lariat F-350 7.3L 4.30 4x4 the TPMS and tire size correction worked as advertised with the exception that it did not show a TCM to relearn. It did have the PCM & AWD relearn. Wrench went away and the speedometer was right on at 2770 with 37x12.50x20 Mickey Thompson Baja Boss AT's. However it would not clear the DTC, no wrench or alarm but it was there. The largest number I could enter was 2699 with no DTC. It looks like it will be off 2mph at 60 which is fine with new tires. Probably could change rear axle to adjust but did not. Forscan Version 2.3.58 was great at letting me know when it wanted accessories on or off. Thank you for the excellent video.

Hey ty for help worked great. I have a forscan ? Due you know the procedure for making time adj on running boards 2024 f450

Rocky this was a well done video. I have a 2023 F550 dually with a super single conversion on it. The a stabilitrac/hill assit deactivaited message comes on. The truck has 40's on it. Have you run into this before? Overland trucks have these tires on it. I have not been able to get anyone of the up fitters to help me with this issue. Side note: It has a Hypertec programmer installed

Thanks!

I am changing pressure and diameter of tires. Thanks. Ever equip a ford that didn't have the b pillar keypad with one? I am wondering how to do that with forescan. I have already installed the keypad, just need the bcm PCM to recognize it.

Do you happen to know if there is a setting to keep 12 volt power all the time? I'm hopefully going to adjust my psi and tire size to 37s put the exterior lights in stealth mode to save battery camping and do the 12 volt mod so my fridge stays on constant

This worked perfect on my truck.I used 2790 for 37 inch Toyo RT’s

Do you have any videos where you program a 2017 through 2019 super duty auto fold mirrors, I’m trying to figure out how to do it on my 2019 before I trade it in just to practice? My question is do I have to swap the pins out on 18 and 19 on both sides? I said it all up correctly, but they’re not folding when I close and they’re not opening when I press open? Any help would greatly be appreciated.. nobody on any of the Facebook forms can tell me or state whether it’s both windows that I need to switch the pins on or just the driver side. I know I got all the right numbers. Since I have a 4 button fob, I used the FC instead of F.

I have a 2021 F450 Diesel with 37" tires, how would i go about chaning the tire size without getting a CEL & wrench icon?

DTC not showing up on newest version of forscan for f250 6.7 any ideas?

For 22 Explorer St is it going to be the same procedure ?

What would you input f450 with 35 inch tires

Awesome, thank you for sharing.

Does anyone know if the 2024 f450 king ranch DRW, has tpms? If not can it be added or turned on in forscan?

What if you can’t see the AWD module? This is a 23 tremor.

Will the speed change work on a 2020 6.7?

Will this void warranty ?

Great content. I have 24 F350 3.31 axel and tried all combinations. I can get the wrench to disappear but I am stll stuck with the TCM code followed by the PCM/AWD after driving. Setting back to stock and taking a drive will get rid of the CELL. Can't seem to find the right combination. Anyone have any luck dialing in 37's with a 3.31 axel ratio?

Rocky, I watch several of your videos. Is this one before the fuel tank upgrade? I noticed the fuel gauge was lower than that video previously. Thanks!!

Were you located? I think I've seen your truck in Fort Worth

Do you only work on 24V truck?

Does using Forscan void warranty?

Thank you for this - it worked perfectly on my F250! Enjoy some beer on me. Cheers!

Why can't we go over 2799 on the tire circumference? I have 38s coming and need to go up to like 3040. It will throw a CEL of you enter too large of a figure? 0:02

great video, do you have to do the relearn on all of them or just the pcm? I just picked up a 2018 f150 and I'm about to put 35s on it and I don't want the wrench to pop up when I calibrate the speedometer, sorry may be a stupid question but I just don't wanna mess up my truck. thanks

Thanks Rocky. Don’t you actually have to change and rewrite what the specific new tire size is also in addition to rewriting what the new tire circumference is?

I have a 2022 SD F350 Platinum. Would I do this same process minus the AWD module?

Thanks for the video, followed the process and speedo was perfect. However, my pre-collision system deactivated and turned on the light. I set it back to the original tire setting and the system works. Do you know if there is an upper limit for the tire size with the pre-collision system. I know in my TRX will not take the increased tire size without impacting the parking sensors. Any input would be appreciated. 2024 F450.

I have a 22 tremor with the factory 35s. It has always read 1 to 2mph lower on the speedo vs gps. Do I need to increase MM or lower MM to try and correct?

Hey do you know how to get past the error code on the 23’s asking for the pcm part number? Or do you have to add that now on these?

Would you have the number for 35/12:50/17? I’m going to try and change the tire size on a 2024 F350 dually.

2799 for the tire circumference keeps a P160a code active on my truck but no light/wrench. 2023 F350 Dually with 4.10 rear end and 37x12.5x20 Nitto Ridge Grapplers - anybody know what will work for this truck? Tried 2790 and 2699 too - same results. Set it back to stock (2429mm for my truck - stock dually tires are only about 31") and was able to clear the code without it coming back. I didn't try 800 random numbers in between because even IF 2699 would have worked, the speedometer would have still been way off. IF we were to change the axle ratio, would other stuff have to be changed too, or just re-learn everything same as when changing tire circumference? It looks like you can pick any number for the axle ratio, so if it's using it for speed calculation, I can figure out the math, just don't want to throw something else off.

I’m getting a P0610 issue now. Can’t get it to go away. Went back to stock size and no luck. Check engine light is on.

What if the truck is tuned - will doing a PCM relearn overwrite or erase the tune?

Wouldn’t the speedometer adjustment be the same for a 22 model?

will this work for 2017 f350 superduty

Can you use a Google chromebook with forscan

I have a 2020 F350 dually with 37s will this work?

Anyone care to share a completely cleared DTIC screenshot?

Any idea if this will work on the 24s? Should, but never know if ford has changed something.

Thanks!
