   Ford 2023 Explorer Owner's Manual, footer ID "2023 Explorer (CTW) Canada/United States of America, enUSA, Edition date: 202209, First-Printing", printed page 376 (PDF p.380 of 573), chapter "Wheels and Tires" > "TECHNICAL SPECIFICATIONS" > "Wheel Lug Nut Torque Specifications". Table reads exactly: "lb.ft (Nm) * | Bolt size" / "150 lb.ft (204 Nm)" / "M14 x 1.5". Footnote: "*Torque specifications are for nut and bolt threads free of dirt and rust. Use only our recommended replacement fasteners." Followed by: "Retighten the lug nuts to the specified torque within 100 miles (160 kilometers) after any wheel disturbance (such as tire rotation, changing a flat tire, wheel removal)." A full-text regex for "bolt circle|bolt pattern|pitch circle|114.3" over all 573 pages returned ZERO hits.

   NEW SOURCE ADDED IN VERIFICATION (not cited by the first researcher). Ford 2022 Explorer Owner's Manual, footer ID "2022 Explorer (CTW) Canada/United States of America, enUSA, Edition date: 202107, First-Printing", printed page 377 (PDF p.380 of 567), "Wheel Lug Nut Torque Specifications": "150 lb.ft (204 Nm)" / Bolt size "M14 x 1.5", single row, no alloy/steel split. This closes the mid-generation gap the original record left open between the 2020 and 2023 books and independently rules out a mid-cycle fastener change. Full-text search for bolt circle / 114.3: ZERO hits.

   Ford 2020 Explorer Owner's Manual, footer ID "Explorer (CTW) Canada/United States of America, enUSA, Edition date: 201902, First-Printing", printed page 370 (PDF p.373 of 536), "Wheel Lug Nut Torque Specifications": "150 lb.ft (204 Nm)" / Bolt size "M14 x 1.5". Footnote wording differs slightly from later books ("Use only Ford recommended replacement fasteners" vs "Use only our recommended replacement fasteners") but the values are identical. Establishes the spec from the first year of the generation. Full-text bolt-circle search: ZERO hits.

Confirms no change through the final year of the generation. Full-text bolt-circle search: ZERO hits.

   Ford 2020 Police Interceptor Utility Owner's Manual (same U625 chassis), footer ID "Explorer (CTW) Canada/United States of America, Police, enUSA, Edition date: 201902, First-Printing", printed page 272 (PDF p.275 of 391): "lb.ft (Nm) 1 | Bolt Size" / "150 lb.ft (204 Nm)" / "M14 x 1.5". Corroborates the torque and thread on the fleet/police variant. CAVEAT I verified: this book does not state that the PIU rides on steel wheels -- its only "steel wheel" occurrence is the generic snow-chain recommendation also present in the civilian manual. Its snow-chain-approved tire list is identical to the civilian one (255/60R18, 255/65R18, 265/60R18, 255/55R20).

   Ford Media Center press kit "2020 Explorer Tech Specs" (4-page PDF, Ford Motor Company), page 2, section "WHEELS AND TIRES". Confirmed the wheel list verbatim: "18-inch painted aluminum (standard on Base)"; "18-inch five-spoke sparkle silver-painted aluminum (standard on XLT)"; "20-inch polished aluminum (optional on XLT, standard on Limited)"; "20-inch hand-polished aluminum (optional on Limited, standard on hybrid)"; "20-inch machined aluminum (standard on ST)"; "20-inch bright machined-face aluminum (standard on Platinum)"; "21-inch aluminum (optional on ST)"; "21-inch premium aluminum (optional on Platinum)". Tires verbatim: "255/65R/18", "255/55R/20", "275/45R/21" (Ford's own stray slash). A regex for "bolt circle|bolt pattern|offset|center bore|114.3" across all 4 pages returned an EMPTY list -- confirming the press kit carries no fitment geometry.

   Ford 2023 Explorer Owner's Manual (Edition date 202209), printed page 20, "At a Glance" > Explorer ST: "Aluminum ST 20 in (50.8 cm) x 8.5 in (21.6 cm) wheels standard; 21 in (53.3 cm) x 9 in (22.9 cm) wheels optional." and "P255/55R20 all-season tires or optional P275/45R21 all-season tires." This is the ONLY place Ford publishes a factory wheel WIDTH for this vehicle. I independently confirmed the first researcher's typo finding: the 2020 edition of the same page reads "Aluminum ST 20 in (50.8 cm) x 9 in (21.6 cm)" -- 21.6 cm is 8.5 in, not 9 in, so the metric value is self-consistent with the 2023 wording and the 2020 imperial figure is the error. Use 20x8.5, not 20x9.

   Ford Explorer Owner's Manual, "USING SNOW CHAINS" section (2020 ed.201902 printed p.~356; 2023 ed.202209 printed p.363; also present 2022 and 2024): "Only use snow chains on the following specified tire sizes:" followed by "255/60R18", "255/65R18", "265/60R18", "255/55R20". 275/45R21 is deliberately absent (chains not approved on the 21-inch fitment). The section also states "Only use snow chains on rear wheels."

   NEW SOURCE ADDED IN VERIFICATION -- cited for the cross-generation safety warning, NOT for this generation's spec. Ford 2018 Explorer Owner's Manual (5th gen, U502), footer "Edition date: 201707, First Printing", printed page 334 (PDF p.337 of 553), "Wheel Lug Nut Torque Specifications". Table reads exactly: "Ib-ft (Nm) * | Bolt size" / "100 (135)" / "1/2-20 x 1.5". This is the primary document that CORRECTS the first researcher's figure: the pre-2020 Explorer is 100 lb-ft (135 Nm) on imperial 1/2-20 studs, NOT the "110 lb.ft (149 Nm)" they reported.
