   2024 GMC Sierra/Sierra Denali 1500 Owner Manual, GM publication GMNA-Localizing-U.S./Canada/Mexico-17382743, PDF asset 85516381C (2025JUN26 3P). Technical Data > Capacities and Specifications, printed p.444 (PDF p.446), final row of the capacities table: "Wheel Nut Torque | 190 Y | 140 lb ft" (the "Y" glyph is N-m, i.e. 190 N-m). Downloaded and text-extracted from GM's own CDN. Programmatic check of the WHOLE book: exactly two lb-ft figures exist anywhere in it - "140 lb ft" (wheel nuts) and "6 lb ft" (the nut on a TRAILER TPMS sensor stem, unrelated). Therefore no alloy-vs-steel and no spare-wheel torque split exists.

   2019 GMC Sierra/Sierra Denali Owner Manual, GMNA-Localizing-U.S./Canada/Mexico-1500-11698638, asset 23400205D (CRC 5/13/19). Printed p.436 (PDF p.437): "Wheel Nut T orque 190 Y 140 lb ft". Start-of-generation confirmation, opened independently. Same single-value check passes: only "140 lb ft" and the unrelated "6 lb ft" trailer-sensor figure appear in the book.

   2022 GMC Sierra/Sierra Denali 1500 Owner Manual, GMNA-Localizing-U.S./Canada/Mexico-15883563, asset 84719636D. Printed p.458 (PDF p.459): "Wheel Nut Torque 190 Y 140 lb ft". Mid-generation (post-refresh) confirmation. I also pulled the 2025 GMC Sierra/Sierra Denali 1500 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-18321580, asset 87855280B), printed p.436, which states the identical "Wheel Nut Torque 190 Y 140 lb ft" - so the figure is unchanged beyond the 2024 cut-off of this record.

   2022 GMC Sierra 1500 LIMITED Owner Manual, GMNA-Localizing-U.S./Canada/Mexico-15664242, asset 85116171C. Printed p.440: "Wheel Nut Torque 190 Y 140 lb ft". THIS DOCUMENT WAS MISSED BY THE FIRST RESEARCHER and disproves their claim that the twin-truck ambiguity was MY2019-only: GM published a separate 2022 Sierra 1500 Limited book alongside the 2022 Sierra 1500 book. Its engine list (L3B 2.7L / L82 + L84 5.3L / L87 6.2L) shows it is the PRE-REFRESH T1 carried into MY2022, not a K2XX. Torque identical.

   2019 GMC Sierra Limited 1500 and Sierra/Sierra Denali 2500/3500 Owner Manual, asset 84161701A (2018APR13). Printed p.451 (PDF p.452): "Wheel Nut T orque 190 Y 140 lb ft", single value. Its engines (L83 5.3L, L96/LC8 6.0L) confirm this is the K2XX carryover, NOT the T1 truck. HAZARD WORTH KNOWING: this is a COMBINED book that also covers the 2500HD/3500HD, which are 8-lug trucks - so the one 140 lb-ft row in it spans both 6-lug and 8-lug vehicles and nothing in it may be used to infer 1500 wheel geometry.

   2024 Sierra 1500 Electrical Body Builder Manual, GM Upfitter Integration, 1,198 pages. Its RPO Code List is Sierra-1500-specific (the engine RPOs in the same list are exactly L3B/L84/L87/LZ0). Verbatim wheel entries include "9C1 WHEEL - 20 X 9.0, J, STEEL, DESIGN 1", "9C1 WHEEL SPARE - 20 X 9.0, J, STEEL", "RBR WHEEL - 22 X 9.0, J, STEEL, DESIGN 1", "RD6 WHEEL - 17 X 8.0, J, STEEL, DESIGN 2", "Q5U WHEEL - 17 X 8.0, J, ALUMINUM", "57N/57R/CWK/Q89/UHN/ULV/WBP WHEEL - 18 X 8.5, J, ALUMINUM", "RD3/RTL/NZD/NZH/WGQ/WJP WHEEL - 20 X 9.0, J, ALUMINUM", "SH0/SMR WHEEL - 22 X 9.0, J, ALUMINUM", "S2B WHEEL SPARE - 17 X 7.0, J, ALUMINUM". The 20-inch and 22-inch STEEL wheels were absent from the first researcher's list. NEGATIVE RESULT: searched the full document for "bolt circle", "bolt pattern", "139.7", "hub bore", "center bore", "thread pitch" - zero hits; the only "M14" strings are an unrelated connector name, "M14A Pickup Box Endgate Lock Actuator".

   2023 Sierra 1500 Electrical Body Builder Manual, GM Upfitter Integration, 1,218 pages (I also pulled and extracted the 2022 edition, 1,172 pages). RPO Code List corroborates the same wheel widths and adds "PXT WHEEL-20 X 9.0, J, STEEL, DESIGN 1", "RBR WHEEL-22 X 9.0, J, STEEL, DESIGN 1", "RQ8 WHEEL-18 X 8.5, J, ALUMINUM", "NZQ WHEEL-20 X 9.0, J, ALUMINUM", plus spares S1U/S4D (18 X 8.5 aluminum) and S2B (17 X 7.0 aluminum), and the full tire matrix (QBN, QDV, RC5, QDF, QDS, XCK, R3O, QFL, QAE, QAB, QFV, XCE + spares QAQ, QBR, XCQ, RHM, RGR, RHF). Same negative result on bolt circle, bore, offset and thread pitch in both editions.

   NEGATIVE-RESULT SOURCE, a document class the first researcher never checked. GM Incomplete Vehicle Documents for the T1XX platform, one per model year MY2019-MY2024 (part numbers 23400327, 84186901, 84557030, 84719647, 84883870, 84989069), published by GM Upfitter Integration as required by FMVSR Part 568 / CMVSR. Each is titled "DOCUMENT FOR INCOMPLETE VEHICLE APPLICABLE TO [YEAR] MODEL YEAR SILVERADO / SIERRA LIGHT & HEAVY DUTY FULL-SIZE TRUCKS & TAHOE SUV". The CMVSS/FMVSS 110 "Tire Selection and Rims" section names only "Tires" and "Wheels" as components not to be altered and defers tire/rim data to the Incomplete Vehicle Label; there is no bolt circle, hub bore, wheel offset or stud thread figure anywhere in any of the six. Cited here as evidence that GM's most technical public vehicle filing also omits the fitment geometry, which is why verified remains false.
