Inflating tyres: the right pressurePhoto: Dirk Zedler
Although pneumatic tyres for bicycles were invented around 120 years ago, cyclists still struggle to inflate their tyres properly today. So here are the ultimate tips. You don't have to tell your cycling mates where you got the tips from ...

TIPS:

- The most common cause of punctures on road bikes is the "snake bite", because the small holes created resemble a snake bite. The inner tube is crushed when riding over edges. Remedy: Adjust the tyre pressure, which you should check regularly. With 60 gram butyl and latex inner tubes, you should inflate daily, with tubeless tyres every two days. Only tyres with butyl tubes weighing more than 90 grams can be left alone for a week.

- Pump rubbers are wearing parts that can actually be replaced on any hand or floor pump. Obtain a replacement from a specialist retailer in good time.

- If you ride high-profile rims, you will need a longer valve, which is why a corresponding spare inner tube should also be in your saddle bag.

- Only use plastic tyre levers to remove the tyres. Using screwdrivers, spanners or similar tools will damage the inner tube and rim.

- The delicate threaded pin in the valve, on which the knurled nut is turned, bends easily - this damages the valve as a whole. Therefore, screw on the otherwise frowned upon dust caps at least for wheel transport.

  Rims differ greatly in the height of the profiles. There are inner tubes with valves of different lengths from almost every manufacturer. Rims differ greatly in the height of the profiles. There are inner tubes with valves of different lengths from almost every manufacturer.
