Now I have found out what I have - U7165, and I have updated it with the latest version - I still can not change the tire size. Please go step by step with me on the screens I should choose when i plug into my truck. skip the turn key off on part. I am not totally clueless I did mine on the 2006 chevy, but the screen choices are different. The only thing it goes to when I want to modify is "speed limit". Help please.

Tire size change is not a option on the U7165.
I think it is going is going to be on one of the future updates for the U7165, but not for sure.
Maybe one of these days a Diablo employee will check these forums and answer some of our questions. They must all be on a very long vacation or just got tired of answering questions about their products.
