Below is an email from a guy I bought my tuner from. My truck is 2015.5 Denali Duramax has. If it is incorrect how and what do I need to program tires to.
So the maximum the ABS module will allow on your truck is 33" tires. If we corrected the speedo for the 34.5" tires it will throw an ABS light above 55mph. Right now it is set to 33". I can email you tune revisions for the 34.5" but it will set a light. This is a limit in the GM software and not the tuning software. This is specific to all 2007.5+ diesels.
