Tire Construction

What kind of compound (Double, Triple) is used for the production of Continental bicycle tIres?

The running surface of a tIre can be made of a single rubber mix (Mono - Compound) or various mixes that are offered by some manufacturers. The running properties of the rubber mix of a tIre is primarily determined by three interacting factors: Grip, rolling friction and running performance. Due to the advantages for the running surface, Continental opts for one mix and its decision has been confirmed by many wins in tIre tests. Therefore Continental tIres stand for constant performance for the entire life of the tIre.

How are bicycle tIres structured?

The carcass, the bead core and the tread are the basic elements of bicycle tIres. In addition a variety of materials are used for tIre protection. A Vectran or PolyX layer under the tread are puncture protection inserts. DuraSkin® protects the sidewall of the tire against external influences and tough conditions.

Which material is used for the carcass?

The carcass is the basic structure of the tire. The construction of the carcass, the material and the thickness of the thread depend on the demands that are placed on the tire. Continental always works with high-quality carcasses made from nylon strings that are first woven and then rubberised. Nylon can be easily combined with rubber and is durable in all types of weather. The thickness of the thread gives the tire its specific attributes. Very fine material makes the tire smoother and protects the carcass from punctures. Coarse fabric is more cut-resistant and makes the tire more robust. The choice of fabric depends on the purpose of the tire.

How can I determine the production date of my tire?

The production date is stated on the sidewall of our bicycle tires and comprises the following elements:

  • The 'K' stands for the product site Korbach. The two triangles indicate that the tire was produced after  2010 - one triangle indicates that it was produced between 2000 and 2009.
  • The circle with the dots means the following: every 'quarter' in the circle can have up to three dots that indicate the production month.
  • The four  'quarters' in the circle can therefore have up to 12 dots and shows the months from January to December.
  • The '0' at the end is combined with the triangles at the start of the code and specifies the year after 2009.

Examples for a tire produced in 2010 and a tire produced between 2000 and 2009:
