2800mm is the maximum number you can input, so make sure you put in something less than that.

I had the same issue that I was able to fix through some forum digging. Give me some time to try and find it again.

Edit: Ok so after you change to tire size, make sure not to go over the max limit like what @Bikeric said. You are going to click on this box (in red).

and then do the "AWD - Module Initialization/Relearn" but make sure to do it twice!

Then clear the AWD DTC code.
You will still have the PCM code now.
After that you want to go to the link provided by @D-TownBorn and go to page 8 and read the 2nd comment on that page. Skip to step 5 provided by @rtaylor. After clearing the DTC code for the PCM this should resolve the issue.

Or just follow all the steps provided by that. I did not change the tire pressure so you can probably skip that step. I have had zero issues since.
