U7137 Failed to update tire size

[scot68]

I have an 06 Durango 5.7L Awd and I'm running beta crom u7137-9t04b_export.crom. I just tried to correct the tire size using the sidwall dimensions and I received the following error message "Failed to update tire size" I ran through the process four times and could not get it to work. I'm trying to change from the stock 245/70/17 to 275/60/20 Any suggestions?

Thanks,
Scott

Yeah it doesn't work, and nobody has an answer for it...

Your kidding me right??? Two reasons I bought this programmer, one was to disable the MDS and the second was to correct the tire size. I also plan to do a gear swap to 3.92's in the near future does that work?

Inputting the sidewall dimensions does not work, and nobody can tell me why...

Try measuring the tire from the ground to the top, and input it in inches

Gear swap shouldn't need any adjustment

Measure?

245/70/17 ~= 23.75"
275/60/20 ~= 26.50"

I'll try that, thanks guys...
