It is hard to imagine that bicycle tyres weren’t filled with air until 1888. Modern tyres, also called rubbers or tires, fit on every bike and can be adapted to specific needs. Whether it's a rapid descent that requires uncompromising cornering behaviour at high speeds or a tour through impassable, unpaved terrain where the knobs of the tyres need to provide plenty of grip, even when centimetres deep in mud or snow. There is a large variety of tyres available today, with widths between 20" and 29", and covering all kinds of different riders’ requirements.

Hose, valves and more
Without a good inner tube, most tyres are useless. The tube goes into the shell during use, the valve is passed through the valve hole in the rim, the flanks of the shell are pulled into the rim and air is inflated. Tubes are sized according to the same specifications as tyres, often in ETRTO measurements. There is another factor to consider:

Having the optimal equipment plays a decisive role in triathlons. For particularly high rims, so-called aero rims, the valves used must be long, in order to reach the top of the valve with the pump. For valves that are supposed to remain hidden in the rim, there are corresponding valve extensions that you can screw on before pumping.

In addition to the length of the valve, the width also plays a role: French valves, also known as Presta or Sclaverand valves, are particularly narrow and very popular due to the pressure behaviour. They can only be used in the wide holes of some MTB rims with an adapter, which is an extension screwed onto the valve that firmly anchors the valve in the hole of the rim. The type of valve plays a decisive role in the choice of pump.

Do you have questions about tyres and inner tubes?

When do I have to change a bike tyre?
With road/everyday tyres and a moderate riding style, the tread pattern is less important. Theoretically, you can ride the bike tyre until the tread is worn and the tyre structure gets visible. For your own safety, however, you should not let it come so far. In practice, fatigue cracks usually occur beforehand anyway or frequent punctures make a change necessary. For mountain bikes, the tread is more important and decreasing grip due to worn knobs is the best indicator for a tyre change.
What tyre pressure/air pressure in bar does a bike tyre need?

How much pressure your bike tyres need strongly depends on the tyre width. Wide tyres distribute the forces over a larger contact surface and therefore require less air pressure. Factors such as the rider weight, tyre construction, rim width, ground conditions, weather and riding style also have an influence, as do modern tubeless and hookless systems. The permissible pressure range is specified by the manufacturer on the tyre’s sidewall and usually ranges from:

  • Road bike tyres between 5.5 and 9 bar
  • Hybrid bike tyres between 2.5 and 6 bar
  • Mountain bike tyres between 1 and 3 bar
Where can I dispose of old bike tyres and inner tubes?
The easy way to dispose of used bike tyres and inner tubes is in the residual waste bin. However, some local authorities stipulate that used tyres must be disposed of in the recycling collection so that the valuable raw materials are not wasted. For the same reason, many bike dealers also offer to dispose of old tyres and tubes. In this way, new tyres can be made from the old ones to save resources and protect the environment. We are also happy to accept your used bike tyres and inner tubes at ROSE Biketown in Bocholt.
Flat tyre on the bike – new tube or repair?
A well-patched inner tube holds air just as long as a new one. So there is nothing to stop you from patching your inner tube several times. This is not only easy on the wallet, but also on the environment. On the other hand, a new inner tube often saves time and nerves in case of a puncture on the road – especially in cold, wet, and muddy conditions or when you’re tired. You can then repair the defective inner tube at home and take it with you as a spare tube on your next tour.
Where can I buy bike tubes from a vending machine?
In many places, you can also buy the number one wearing part in cycling from special bike tube vending machines. You will find such tube vending machines frequently in front of bike shops, at cycling clubs, in bike parks or in areas with a high level of cycle tourism.
