A brief history of Tires
In the early days
In the beginning tires were constructed with iron and placed to wheels produced from wood. Wheelwrights forged the tires in high temperature fires. After that they affixed the tire to the wheel and let it cool so it would contract tightly. The outer ring “tied” it all together.
The original pneumatic tire was made by John Dunlop for a bike his son used in 1887 to minimize the instability of rough roads.
A pneumatic tire are made with bendable components (most commonly rubber alongside with materials like wire and fabric. The original tire makers were founded in the beginning of the last century and rose alongside the auto industry. Now over 1 billion tires are created each year.
Some tire highlights are as follows:

In 1843 Goodyear created vulcanization.
In 1889 Dunlop creates pneumatic tires.
Michelin manufactured the original removeable pneumatic tire in 1891.
In 1906 the original pneumatic aircraft tire was used.
BF Goodrich created the original synthetic rubber tire.
Michelin designed the original radial in 1946.
In 1968 the Department of Transportation’s demand requiring numbers on all newly built tire.
Pirelli invented the original wide radial tire.
An interesting fact: the word tire derives from to tie or attire and is also accurately spelled as tire or tyre.
Final Notes and more
Throughout time tires have been made in five major ways: solid, semi-pneumatic, belted bias, bias, and radial. If this mini tire history has helped, you might think about visiting Car and Tire info or Tire info. Thank you for visiting and best of luck with all your car needs.

Organic Latex History and Production
Where does Natural Latex comes from? Natural Latex is made of the latex which is extracted from ducts of actual rubber tree (Hevea Brasiliensis) from South-East Asian countries.
The leading countries in production of natural latex are:
Thailand
Indonesia
Malaysia
Sri Lanka
The rubber tree life cycle is around 32 years. The latex is typically harvested when the trees are 5-7 years old.
The method of latex extraction is known as “rubber tapping”. Tappers usually start tapping early in the morning when the internal pressure of the tree is highest. The idea is to tap the rubber tree vessels without harming the tree’s growth. It is very important for the tappers to tap rubber tree attentively. Rubber tree life longevity depends on accurate and precise work of the tapper. The trees will drip latex for about four hours, stopping as latex coagulates naturally on the tapping cut thus blocking the latex tubes in the bark. Then all this milky sap-like fluid is collected in small buckets. Tappers usually rest and have a meal after finishing their tapping work then start collecting the latex at about midday. Rubber tree is usually tapped no more than once in every two days.
The botanical-derived Latex is known to be naturally:
anti-microbial,
dust mite resistant
mildew resistant
hypo-allergenic
flame retardant
There are two methods of natural rubber processing:
Talalay method
Dunlop method
The Talalay method is a proccess of producing molded pieces of natural latex foam rubber. A natural liquid latex rubber base is introduced to a closed mold that has been vacuumed of air. The mold is then frozen to stabilize the cell structure. Carbon dioxide gas is introduced and the mold is heated to cure the rubber. The Talalay Latex rubber manufacturers claim that talalay method of vulcanization is non-toxic and natural. However Talalay Latex rubber has petroleum added in the form of artificial vanillin. The vanillin contains dimethyl sulfate and is highly toxic according to a Virginia University study.
Pure natural Latex which acquired through a Dunlop method of vulcanization is using no petroleum based ingredients, harsh chemicals or pesticides. Dunlop method of vulcanization is an original straightforward process of converting rubber tree sap into a solid form. This method involves first whipping the latex liquid with air to make a foam, then pouring the latex liquid into a mold and heating it till it vulcanizes.
Natural Latex is produced through a Dunlop method of vulcanization uses the following ingredients:
1.90-95% of Natural Rubber
2.2-3% Zinc Oxide
3.1-2% Fatty Acids and Soaps
4.1-2% Sulphur and 1-2% Sodium.
At the end manufacturing process Latex rubber is rinsed out with water several times to ensure where is no soap residue or anything else left. As the result we get approximately 99% – 100% natural Latex rubber. It is then moulded into different shapes, sizes and predetermined degrees of firmness. The durability, flexibility, resilience and hygienic properties of Natural Rubber allows Latex Foam to be used for different kinds of purposes.
Be aware that some manufacturers market 100% latex which still contains synthetic foam. So if it’s not branded 99% – 100% natural, it’s probably anything but! Natural Latex is 100% renewable and sustainable resource, which is kind to the environment, and healthy for your body and general well-being.
Organic Latex Rubber pillows and mattresses are becoming very popular. Many people choose natural Latex products over synthetic memory foam, which is made with chemicals and petroleum based ingredients. Organic rubber pillows and mattresses are naturally cushioning to your body, providing you with chemical-free, restful sleep!
