    2017 GMC Sierra Cruise Control Issues

    Truck is all stock except for a small lift and has 35in tires. I used the gear/tire wizard to adjust the speedo and now cruise isn't working. First time I've had this issue. Any ideas?

    What if you set the tire size back to stock, does it still do it?

    This would rule something out if nothing changed.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    Was planning on giving it a try when I got a chance. Honestly not even sure that it worked before the change.

    Manually adjust the VSS tire Revs per. Its usually +/- 3%.

    Did you get this figured out? I am having the same issue on a 2017 Silverado with 35" tires.
