I`ve had 275/65/r18 on the10 speed biturbo for 12,000 k`s now, originals wre 265/60/ r18,; I wasn`t happy with the way the car was running, came here and used the tyre calculator and followed the instuctions- all good now - way better economy and trans is way better also.

Thanks so much for your efforts on this site

Hi all, I have a Next-Gen Everst Sport V6 with 275/65R18's.

True Circumference mm: 2559
Ford Corrected Circumference mm: 2475

Required BCM value at 726-12-01 is xxxx-09AB-xxxx

I updated this value under bcm asbuilt and did theTCM relearn but keep getting numerous error codes.

I reset this to default and cleared the error codes.

I tried changing the tyre circumference under bcm non asbuilt but got more error codes, the service message and a check 4x4 message.

I reset this to default and cleared the error codes.

I know 0977 is the max value on the 6 speed but read that I should use the value shown in the calculator for the 10 speed.

Am I missing something Stewart?

Hi guys,

My Ranger is currently remapped or tuned. Is it safe to relearn PCM?

Yes.

Was your BCM value at 726-12-01 xxxx-09AB-xxxx?

If the numbers are all correct and the speedo is still showing 100km/h when GPS shows 96km/h can i correct this another way?

No. Speedometer cannot be independently changed and the 4% is written in the firmware.

bummer! thanks though

If you read the speed via the OBD port using a Scangauge or similar, you'll see the speed without the 4% factor. If your tyre size settings are correct then that should correspond with your GPS.

Hi Stewart,

Just confirming we only Make required changes in BCM asbuilt ?

My Required BCM value at 726-12-01 is --- xxxx-09DC-xxxx for the 285/70r/17 wheels and Tyres.

Do i need to change the original Tyre Circumference from 2340mm to 2610mm too?

I have a PX3 BiTurbo 10 Speed.


cheers

Do exactly as per the instructions.

Done with out changing the tyre circumference and much better now.. gps show 3km/h less than the cluster.

Thanks Stewart..

3 or 4 depending on tread depth is perfect.

Can somebody tell me if this works for next gen ranger have fitted up 285 70 17 tyres and want to correct speedo thanks

22.75 2ltr wildtrack
I changed my BCM value from 725-12-01-C100-4D50-4E20 to 726-12-01 to xxxx-09DC-xxxx for the 285/70r/17 wheels and Tyres.
Click write and it comes up with a check sum error
Ignition off and on
And retrained the TCM.
But the are DTC’s I can’t clear.
I tried three times, go back to standard and the codes clear.
Any ideas what could be causing this?

I also tried change the tyre circumference but it comes up with a transfer error alarm so back to standard

As per my note on the calculator "This is not applicable to NextGen"

22.75 would be a NextGen so......................................................
