On trucks can you just type in the new size under the speedometer calibration to adjust for the new tire size?

Yes, but you also nee dto click the [Save] button to copy the newly calculated values back to the calibration details below. I fyou have an automatic transmission, you may use the Adjust button to automatically adjust your shift points.

Thanks for the help. Also how do you do a corvette? Isnt it differnt?

Yes it is different, the corvette has the speedo pickup on the rear axle not the drive shaft. In that case you need to have the "Transaxle" checkbox ticked. See image.
