Max tire circumference 2750mm

[Yeti-X]

So I finally got around to playing with my forscan and the largest tire circumference that it would take is 2750. Is there a way around this?

37’s?

I was able to go up to 2880, brought it back down to 2800 for my 37’s
The calculations don’t make sense, because at 2800 that should be a 35” tire diameter, but it syncs up perfect with every GPS I’ve tried

Besides the speedo, is there anything the calibration affects?

No. Mine has been changed for 14k miles with zero issues.

I tried 2899, 2850, 2800 on down even 2791 and nothing and yes 37's

Are you clearing any codes and resetting/relearning vehicle data after you change the number?

yep did a pcm relearn and initialize as well awd relearn and initialize one of the codes I had was the fact that the circumference was too large and the other code it got bad information becasue the circumference was too large
