How is a tyre for your car made?

 

Your tyres are the single most important safety feature your car has.

 

A good tyre increases road grip and also performance and fuel economy. 

 

So, how does it go from rubber on a tree to the black tyre on your car?

 

There are three main processes in making a tyre.

  1. Buy all the raw materials needed and turn them into the forms used to make your tyre.
  2. Physically building your tyre
  3. Vulcanisation and Quality Control.

 

Raw materials & the conversion into a usable form.

 

Each tyre manufacturer spends massive amounts perfecting the exact ratio of each component used in making your tyre; in most cases, these are a closely guarded secret.

High Quality Steel is a major component in the production of tyres chemical compounds with are normally a closely guarded commercial secret Natural Rubber is also harvested and then used to make your tyres Man made fibers also  help strengthen your tyre

  1. Steel is used to make steel cords, usually only visible if your tyre is completely worn out and should not be visible on any tyre fitted to your car.
  2. One of the secret ingredients is a cocktail of chemicals, and this mixture will have been fine-tuned to increase wear and grip and, fingers crossed, prolong the life span of your tyre. 
  3. Natural Rubber is farmed, and the latex ( a milk-coloured solution ) solidifies when certain acids and other chemicals are added.  
  4. Artificially produced textiles such as polyester and nylon are added to strengthen the tyre further.

 

 

Building your tyre

 

The various components are combined in a complex process involving bringing the different elements together into a green tyre shape. 

 

Vulcanisation & Quality Control.

Again, this is a closely guarded secret, as each ingredient used to make your tyre will react differently. Think of it as baking a cake in a pressure cooker. Exact temperatures and pressures are applied, and the pattern and tread are formed. It is then tested for quality control.
