How Petroleum Became a Major Source of Tyre Raw Materials

 

Every time your car moves on the road, it is standing on something much more complex than plain rubber and air. Most people think tyres are made mostly from natural rubber taken from trees. But that is not true. A substantial share of the raw materials and raw-material costs involved in tyre manufacturing is linked to petroleum, with some industry estimates putting the crude-linked share of raw-material costs at around 60–70%. In many ways, a tyre is closer to a plastic bottle or diesel fuel than to rubber from a tree.

This one fact explains a lot. It highlights why tyre prices fluctuate with crude oil prices. It explains why tyre companies are under pressure to become greener. And it explains why Middle Eastern countries have quietly become important players in the tyre supply chain. In this post, we look at what tyres are really made of, why petroleum plays such a big role, and which tyre materials come from the Middle East.

What Are Tyres Actually Made Of?

A tyre is not one material shaped into a circle. It is a mix of more than 200 raw materials, layered and blended. Broadly, these fall into a few groups:

• Natural rubber
• Synthetic rubber (made from petroleum)
• Carbon black and silica (materials that add strength)
• Steel and fabric cords (for structure)
• Chemicals such as sulphur, oils, resins, and antioxidants

At first, this looks like a balanced mix. But several important tyre materials and their production costs are linked to petroleum, directly or indirectly. This helps explain why estimates of petroleum-linked raw-material costs can reach around 60–70% in some industry assessments.

Why Petroleum Dominates Tyre Manufacturing

Petroleum enters tyre making in more ways than people realise. It is not only about synthetic rubber. Crude oil is also the starting material for carbon black, several process oils, resins, and even some of the chemicals used to cure (harden) rubber during production.

Synthetic rubber is made from petroleum-based building blocks called butadiene and styrene. In many modern passenger car tyres, synthetic rubber forms an important part of the rubber compound and is often used alongside natural rubber. Add carbon black, oils, and other petroleum-based chemicals, and it becomes clear why tyre makers watch crude oil prices so closely. Changes in crude oil and petrochemical prices can increase the cost of several tyre raw materials, although the effect on tyre prices depends on contracts, inventories, exchange rates and other manufacturing costs.

The Petroleum-Linked Breakdown, Explained.

Here is a simple look at the major tyre materials and inputs that are linked to petroleum:

• Synthetic rubber (SBR, BR, IIR): made from petroleum chemicals, used for tread strength and flexibility
• Carbon black: Carbon black is generally manufactured from heavy hydrocarbon feedstocks, commonly derived from petroleum refining or coal-tar-related sources, using controlled thermal processes.
• Process oils: petroleum-based oils used to soften rubber and make it easier to work with
• Resins and tackifiers: usually made from petroleum by-products, used to help rubber layers stick together
• Chemical additives: many curing agents, accelerators, and antioxidants also come from petroleum.

Taken together, petroleum-derived and crude-linked materials represent a substantial share of tyre raw-material inputs and costs, although the exact percentage varies by tyre type, manufacturer, formulation and how petroleum dependence is measured.

 

Natural vs. Synthetic Rubber

Natural rubber comes from the sap of rubber trees, mostly grown in Thailand, Indonesia, and Vietnam. It has excellent elasticity and heat resistance, which is why it is still used in truck and aircraft tyres, where durability matters most.

Synthetic rubber, on the other hand, is made in a lab using petroleum-based chemicals. It is cheaper to produce in large amounts, easier to customise for things like wet-road grip or fuel efficiency, and it does not depend on weather, land, or farming supply chains.

Most tyres today use a mix of both types.  But the growing use of synthetic rubber is the main reason petroleum has become so important in the tyre-making process.

The Middle East's Role in Tyre Materials

This is where things get interesting. The Middle East does not grow rubber trees, but it holds some of the largest crude oil and natural gas reserves in the entire world. This makes the region a key supplier of the chemical building blocks used in synthetic rubber, carbon black, and other tyre-related chemicals.

Countries like Saudi Arabia, the UAE, Qatar, and Iran have invested heavily in their petrochemical industries over the last twenty years. Instead of only exporting crude oil, the region has developed substantial petrochemical production and exports a range of chemicals and synthetic-rubber-related materials used by industries around the world, including tyre manufacturing. This shift matters because the Middle East is no longer just an energy supplier to the tyre industry. It has now become a direct supplier of raw materials too.

Tyre Raw Materials Sourced From the Middle East

Based on current trade patterns, here are the main tyre-related raw materials commonly sourced from the Middle East:

1. Crude oil and naphtha – the base material for almost all petroleum-based products used in tyres
2. Butadiene – a key building block used to make synthetic rubber such as SBR and BR
3. Styrene – combined with butadiene to make styrene-butadiene rubber (SBR)
4. Carbon black feedstock (petroleum-based oils) – used to make carbon black, a major strengthening material
5. Synthetic rubber (SBR, polybutadiene rubber) – increasingly made and exported directly by Gulf petrochemical companies
6. Process oils – used to soften and process rubber compounds
7. Resins and hydrocarbon tackifiers – help tyre layers stick together
8. Sulphur – a by-product of oil and gas refining, widely exported from Gulf refineries, used to harden rubber

How This Affects Tyre Prices

Because such a large share of tyre materials is tied to crude oil, tyre prices tend to move along with global oil prices. Changes in crude oil and petrochemical prices can increase the cost of several tyre raw materials, although the effect on tyre prices depends on contracts, inventories, exchange rates and other manufacturing costs. These costs are often passed on to buyers.

This dependency also creates supply chain risk. Any disruption to Middle Eastern oil and petrochemical exports, whether from conflict, sanctions, or production cuts, can affect tyre factories thousands of kilometres away. This can affect delivery times and even the price of new vehicles in showrooms.

The Push Toward Greener Tyres

Because of this heavy reliance on petroleum, tyre makers are now researching alternatives. Some emerging options include:

• Bio-based synthetic rubber made from renewable sources like sugarcane or corn
• Recycled carbon black recovered from old tyres through a process called pyrolysis.
• Guayule and dandelion plants as alternative sources of natural rubber
• Greater use of recycled steel and fabric in tyre construction

Major global tyre brands have already set targets to increase the use of sustainable and renewable materials in their tyres over the next decade. However, replacing petroleum-based materials on a large scale is still slow and costly, so oil-based materials are likely to remain dominant for years to come.

Conclusion

The idea that tyres are generally made of rubber is outdated now. In reality, a substantial share of modern tyre manufacturing depends on petroleum-derived materials and petrochemical inputs, including synthetic rubber, carbon black, process oils, resins and chemical additives.

 

 

The Middle East, with its large oil and gas reserves and growing petrochemical industry, has become a key supplier of these materials to tyre factories.

 As oil prices keep changing and the demand for sustainability rises considerably.  The world tyre industry stands at an interesting crossroads, balancing cost, performance, and a slow shift toward greener materials. The tyre industry's future depends heavily on how it reduces its dependence on crude oil.

FAQs

1. Is it true that 70% of tyre raw materials are petroleum-based? Not necessarily. Petroleum-derived materials make up a substantial part of tyre manufacturing, but there is no single 70% figure that applies to every tyre. The percentage varies according to tyre type, formulation and whether the calculation is based on material weight, raw-material cost or petroleum-derived content.

 

2. Why don't tyre companies use natural rubber instead? Natural rubber depends on weather, land, and farming supply chains, which makes it harder to scale up and more expensive. Synthetic rubber is more consistent and can be designed for specific performance needs.

3. Which Middle Eastern countries supply tyre raw materials? Saudi Arabia, the UAE, Qatar, Iran, and Kuwait are among the leading suppliers. They export crude oil, naphtha, butadiene, styrene, and synthetic rubber to tyre makers worldwide.

4. Do rising oil prices really affect tyre prices? Yes. Since a large portion of tyre materials comes from petroleum, a big rise in crude oil prices usually leads to higher tyre production costs, which are often passed on to buyers.
