Speed calibrating correcting?

2008 Colorado 2.9 auto

Going from the factory wheel size of 215 70 15 to 255 70 16 and the speedometer is 7mph slower reading to actual mph.
If ip cluster reads 50 mph the vehicle is actually going 57mph.

Where is the setting to rectify the indifference?

Thank you

Does using the gear/tire wizard under the edit tab help?

im not seeing that option.

Post the file.

doh I had the wrong file open. But why is that option not there for all gm dodge ford vehicles?

Thanks 5FPD for the help. Now to fiddle with it.

now i can't save the file under the same vin I already licensed. What gives?
