Tire Characteristics

What is the rolling resistance of my tire?

The rolling resistance depends on the air pressure, profile, tire design, material quality and tire width. Tires by Continental always offer the best possible combination of properties thanks to their purpose-oriented design and optimised rubber mix. Less profile and lower weight are guarantees for smooth running tires. Choose tires for your specific purpose after asking the advice of your dealer. Remember that wide tires of the same type and with same air pressure run better and more lightly than narrow tires.

What is the task of the tire profile?

On smooth and firm terrain (e.g. asphalt and concrete) tires adhere thanks to the friction between the rubber and surface. A profile is not required, in fact a grip would be detrimental because less material is engaged with each other.  Less profile results in better rolling resistance. There is no reason to worry about aquaplaning with bicycle tires. Therefore, tires with very little or no profile at all should be the first choice for firm terrain with grip.
On rough or loose surfaces, the grip of the tire rubber is inadequate, the tires will slide. Therefore profiles are required on surfaces of this kind because this creates additional interlocking between the tires and the surface. The deeper and looser the surface, the better it is to have a deep profile. The running properties on firm surfaces however suffer. Therefore it is impossible to recommend on single tire for mountain bikes. Enthusiastic riders are therefore well advised to use different tires in different areas and situations.

What is the load-bearing capacity of a bicycle tire?

Normal bicycle tires do not have load carrying classes like automobile tires. Only ECE - R75 certified tires have a load bearing index like car tires. In general though, wide tires with a high air pressure are best for heavy loads. In principle, the pressure should be adapted proportionally to the weight.

What is the mileage of a tire?

It is not possible to make statements about the mileage of a tire, because this depends heavily on the way it is ridden, the surface etc. Tires should be replaced at the latest when the rubber running strip or the profile of a mountain bike tire is worn. Please also note the wear indicators defined by the code TWI on the sidewall of the tire.

Which tire fits to what rim?

For clarification on sizing, all Continental bicycle tires are sized according to the ETRTO (European Tire and Rim Technical Organisation) format: tire width [mm] x tire rim diameter [mm], for example 23-622. This is stated on the sidewall. The internationally recognised ETRTO standard should always be used when in doubt. In general, Continental recommends that bicycle tires only be mounted on hook edge type rims because this type of rim holds the tire more securely, especially with air pressures exceeding 3 bar. An overview of which rim widths fit which tires is available from ETRTO.

Which wheel circumference should be set at the bike computer?

The wheel circumference depends on the air pressure, the weight-loading and the rim. For this reason it is not possible to specify the exact measure. Here is an overview about approximate wheel sizes for popular tires:

Does Continental produce coloured tires?

Continental also produces coloured tires in the race and city/trekking segment. Coloured city/trekking tires are used as style elements. In the race segment, colours are limited to the sidewalls because of performance losses.

Do Continental bicycle tires contain animal fat?

Our bicycle tires are made of natural vegetable raw materials. No raw materials, reagents and substances of animal or human origin are used to process our tires.
