Carbon Footprint of a Car Tire: LCA Benchmark (10,000 Simulations)
Last updated: 2026-05-06
Based on 10,000 Monte Carlo simulations using the Ecoinvent 3.9.1 database and aligned with ISO 14040/14044 methodology, the median carbon footprint of a single car tire is 41.4 kg CO₂e, with a mean of 41.8 kg CO₂e. The 80% confidence interval spans from 32.1 kg CO₂e (P10) to 51.9 kg CO₂e (P90), reflecting real-world variability in materials, manufacturing processes, and geographic context. This benchmark aggregates data from published EPDs, industry guidelines, and peer-reviewed literature to provide a robust reference for LCA practitioners and sustainability professionals.

Key Findings
- The median carbon footprint of a car tire is 41.4 kg CO₂e per unit, with a mean of 41.8 kg CO₂e across 10,000 simulations.
- The 80% confidence interval ranges from 32.1 kg CO₂e (P10) to 51.9 kg CO₂e (P90), indicating a spread of nearly 20 kg CO₂e across plausible real-world scenarios.
- The standard deviation of 7.7 kg CO₂e — roughly 18% of the median — reflects meaningful variability driven by differences in material composition, energy sources, and manufacturing location.
- Seven published EPDs were incorporated as reference points, alongside industry guidelines and peer-reviewed literature, grounding the benchmark in verified industry data.

Methodology: ISO 14040 Monte Carlo Simulation
This benchmark is generated using 10,000 Monte Carlo simulations drawing on the Ecoinvent 3.9.1 background database, with characterization factors aligned to IPCC AR6 GWP100, and conducted in accordance with ISO 14040 and ISO 14044 life cycle assessment standards. Probabilistic distributions are applied to key input parameters to capture uncertainty across material, energy, and process inventories.
Frequently Asked Questions
What is the carbon footprint of a car tire?
Based on this benchmark, the carbon footprint of a single car tire is approximately 41.4 kg CO₂e (median value). The 80% confidence interval ranges from 32.1 kg CO₂e to 51.9 kg CO₂e, meaning most real-world tires fall within this range depending on their specific materials, manufacturing location, and energy mix. The mean across all 10,000 simulations is 41.8 kg CO₂e.
How is this benchmark calculated?
We run 10,000 Monte Carlo simulations using the Ecoinvent 3.9.1 life cycle inventory database, applying probabilistic uncertainty distributions to key input parameters such as material quantities, energy consumption, and background processes. The global warming impact is calculated using IPCC AR6 GWP100 characterization factors. The resulting distribution yields aggregate statistics including median, mean, standard deviation, and percentile ranges (P10–P90). The methodology follows ISO 14040 and ISO 14044 standards.
Which life cycle phase contributes the most?
Phase-level contribution data is not broken out in this aggregate benchmark. However, industry literature and published EPDs consistently indicate that raw material production — particularly the extraction and processing of natural rubber, synthetic rubber (derived from petroleum), and reinforcing materials such as steel and carbon black — is typically the dominant contributor to a tire's cradle-to-gate carbon footprint. Manufacturing energy consumption also plays a significant role, while end-of-life impacts vary widely depending on regional waste management infrastructure.
How can I reduce the carbon footprint of my car tire?
Several levers can reduce tire-related carbon emissions. On the production side, increasing the share of natural rubber from certified sustainable sources, using bio-based or recycled materials, and sourcing manufacturing energy from renewables can meaningfully lower emissions. On the use side, maintaining correct tire pressure, avoiding aggressive driving, and extending tire lifespan all reduce the per-kilometre footprint. At end of life, choosing recycling or energy-recovery pathways over landfill helps recover embedded value. The wide P10–P90 range of 32.1–51.9 kg CO₂e in this benchmark shows that design and sourcing choices can make a substantial difference.
