Tyre Characteristics

What is the rolling resistance of my tyre?

The rolling resistance depends on the air pressure, profile, tyre design, material quality and tyre width. Tyres 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 tyres. Choose tyres for your specific purpose after asking the advice of your dealer. Remember that wide tyres of the same type and with same air pressure run better and more lightly than narrow tyres.

What is the task of the tyre profile?

On smooth and firm terrain (e.g. asphalt and concrete) tyres 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 tyres. Therefore, tyres 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 tyre rubber is inadequate, the tyres will slide. Therefore profiles are required on surfaces of this kind because this creates additional interlocking between the tyres 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 tyre for mountain bikes. Enthusiastic riders are therefore well advised to use different tyres in different areas and situations.

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

Normal bicycle tyres do not have load carrying classes like automobile tyres. Only ECE - R75 certified tyres have a load bearing index like car tyres. In general though, wide tyres 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 tyre?

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

Which tyre fits to what rim?

For clarification on sizing, all Continental bicycle tyres are sized according to the ETRTO (European Tyre and Rim Technical Organisation) format: tyre width [mm] x tyre 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 tyres only be mounted on hook edge type rims because this type of rim holds the tyre more securely, especially with air pressures exceeding 3 bar. An overview of which rim widths fit which tyres 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 tyres:

Does Continental produce coloured tyres?

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

Do Continental bicycle tyres contain animal fat?

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