2021 Ranger Hp tuners how to adjust tire size

[Hizdudeness]

I have a tune from Torrie which operates amazing ofc. I am going to to 295/35/18 tires on different wheels. (pics when completed) I am looking for the way to change this ratio without it being done in the tune. When using VCM scanner under controls and special function I have two tabs engine-which has crank relearn and KAM position reset then another tab labeled transmission there is reset adaptives. That is it. Only other functions is read DTCs and Log. Besides the help stuff for updating firmware and license stuff.

I remember pretune I had a place for changing tire size in mm and another tab to choose learn value from bcm or use value. Anybody else have this problem or is it just me? This may have been under editior though I cant recall. I know sct is unable to adjust tire size value in 2021 but can on the 2019 and 2020. Do I need to get a cable and do this in Forscan now? Anybody with a 2021 that has changed tire value for speed correction care to chime in on how you fixed the speedo? Per tire calculator mine would be off by 10 mph post change and I am not ok with that.

Fixed with Forscan. The value used for 295/35/18 was 2014mm. This was for Toyo Proxes AS. At 70 mph speedometer indicated two gps devices/aps confirm 70mpg dead on. Picture to show comparison of stock 265/60/18 compared to the new setup. The stock wheel is directly against the new wheel tire. Ground to top of old tire combo was 30.2", new tire was 25.8" Effective rear gear ratio changed from 3.73 to 4.27. It accelerates way more lively from a stop. New wheel and tire combo is 6lb lighter each and has almost 3" more contact patch. Very happy with this setup. Now just have to avoid potholes!

Sorry the pic is a movie, must have fat fingered the button.
