Hello I will help,

Yes as long as you don't go too radical then computer can be programmed with the size of the tires you will be running so the speedometer reads correctly. More importantly the traction control/stability system will be happy.

Please let me know if you have further questions, if nothing further please complete the rating

Thanks

Do you think a non-GMC authorized dealer will be able to this?
Do you know how it is done?
Chevy Mechanic: George H., ASE Certified Technician replied 7 months ago

Sorry I was offline when you replied.

Yes if a shop has a GM GDS 2 tool or an up to date pro level scantool they can set up the computer for the new size. It is one of the menu options on the scantool and is just a matter of entering the new information to the computer memory.

Please let me know if you have further questions.
