Documented applications
- 2016 Factory-verified
only in: Police Vehicle: S; the lists print P265/60R17 SL 108V BW AL3; the 2017 shared list also prints it, but no Tahoe page of 2017 or later in the sources does, so 2017 is not claimed
This page aggregates every documented appearance of ZAK in the Chevrolet reference. Confidence and citations are shown per application — the same code can be better documented in one year than another.
