Sulphur (Sulfur) is added to rubber in the process known as vulcanization.
rubber...
''Rubber'' is not an element, it's actually a compound it's formed with other element's needed.
Most car tires are made of rubber, but not expanded rubber. That's a completely different thing, as it has air pumped into the material during hardening, creating a softer compound.
no, both natural and synthetic rubber are polymers
NO
The vulcanization of rubber is a chemical process where you convert rubber, or other related polymers, into a more durable material by way of the addition of sulfur. The reason why you can not use any other element to do this is because other elements do not produce the same results.
Carbon is the main hardening element in steel. However, increasing the hardness decreases the ductility. Strength in this case is relative.
There is not single element in bicycle tires. The rubber itself is vulcanized rubber, which contains carbon, hydrogen, and sulfur.
