Good Evening!
I have seen many asking what the biggest tires are that can be run with a level on the newer Sierra models. I have also seen many ask if you can do a level and bigger tires if you have super cruise.
I have owned a 19 Denali 1500, 22 Denali Carbon Pro, and now 24 Denali Ultimate with supercruise. All three were leveled and all three had Nitto Tires on them.
Here is the 19 with a 1.5”Level and 33x12.5r22 Nitto Terra Grapplers
Here was the 22 with a 2” Level and 285/50/r22 Ridge Grapplers
Here is a 24 with a 1.5” level and 285/55/r22 Ridge Grapplers
To consolidate the thoughts on the tire sizes with the 1.5-2” level.
33x12.5xr22: No Trimming and very minor rubbing on rough terrain
285/50/r22: No Trimming and no rubbing (but was a 2” level)
285/55/r22: Minor Trimming REQUIRED and still some minor rubbing during full turns on uneven terrain
In all models and cases the super cruise and lane assist were not affected and work great after the level and tire change.
There was some minor distorting on the 360 camera view on the 19, a little less on the 22, and none on the 24 after the camera angles changed from the levels and tires.
let me know if yall have other questions.
