Passenger car tyre
One kilogram of passenger car tyre
This page shows what the product is made of and where each figure comes from. It shows no death toll. The toll is computed from this bill of materials from session 19, and published only once it has an uncertainty interval and has passed a backtest.
A passenger car tyre by mass, as the European tyre industry's composition table gives it: 47% rubber and elastomers, 21.5% carbon black, 16.5% metal, 5.5% textile, 1% zinc oxide, 1% sulphur and 7.5% additives. Only the metal reaches a register material here, as steel; natural rubber, carbon black and the rest are not yet in it.
- Overall grade — medium

What it is made of
Each line is one component of one kilogram of passenger car tyre: how much of it goes in, how much had to be produced for that, and where the figure comes from.
Down to raw materials
The whole chain multiplied out — everything one kilogram of passenger car tyre needs, through every intermediate product, with every loss on the way included.
| Input | Per functional unit |
|---|---|
| Coal and lignite | 97.5 g |
| Iron ore | 187 g |
| Additives (not in the register) | 75.0 g |
| Carbon black (not in the register) | 215 g |
| Electricity, electric arc furnace route (not in the register) | 0.114 MJ |
| Limestone (not in the register) | 35.5 g |
| Recycled steel (scrap) (not in the register) | 49.6 g |
| Rubber and elastomers, natural and synthetic (not in the register) | 470 g |
| Sulphur (not in the register) | 10.0 g |
| Textile reinforcement (not in the register) | 55.0 g |
| Zinc oxide (not in the register) | 10.0 g |
An input marked “not in the register” is counted by mass and reaches no supply chain yet. Industries appear as the euros or tonne-kilometres the bill of materials gives them.
How much of it is explicit
100% of this product’s mass is explicit in its own bill of materials.
Its whole chain draws on 1.20 kg of materials, losses included. 24% of that is registered raw materials — the part the model can trace harm to — 76% is inputs not yet in the register, and 0% is a declared remainder.
In the input–output model it belongs to “Manufacture of rubber and plastic products” (FIGARO industry C22).

The number this page does not show
The harm in this chain is not shown.
The model allocates the harm counted where each raw material is produced to the products that use it. That number is a count of people with a run behind it and no uncertainty interval yet, and nothing of that kind is published before the backtest of session 21. What this page can show without it is the structure: what the product is made of, and where each part of that knowledge comes from.
