decoderpo.com's 2024 ALL-NEW Traverse order guide page lists it on its Wheels tab (orderable wheels); the page is a T3 mirror of GM's guide and the repository holds no GM document for 2024; the page words it as "LPO, 22" (55.9 cm) Black aluminum wheels"

This page aggregates every documented appearance of SAY in the Chevrolet reference. Confidence and citations are shown per application — the same code can be better documented in one year than another.
