Basis~35 kg CO2e/tire cradle-to-gate (raw materials + manufacturing, excl. use-phase rolling-resistance fuel, per this list convention) x4. Revised 2026-08-13 after a user flagged the prior figure as implausible: triangulated from a Devera LCA-benchmark aggregation (~41 kg CO2e/tire cradle-to-gate median, 32-52 kg 80% CI) and a Goodyear-cited finding that ~94% of a tires total lifecycle GHG comes from the use phase, implying manufacturing+materials is a small share. No single clean peer-reviewed cradle-to-gate figure was accessible, so this stays an estimate.

Built up from components rather than measured directly. Treat it as the right order of magnitude, not an exact figure.
