Le biciclette da trekking sono spesso usate per coprire lunghe distanze con bagaglio anche su terreni off-road; per questo motivo hai bisogno di un pneumatico speciale. Pneumatici per bici da trekking sono adatti per terreni come strade con ghiaia e piste forestali; più spessi rispetto agli pneumatici per bici da corsa ma più sottili rispetto alle gomme di una mountainbike per dare bassa resistenza al rotolamento e resistenza.
Do you have questions about hybrid tyres?
On the sidewall of the tyre you will find information on the air pressure approved by the manufacture in bar/PSI, as well as the size of the tyre, usually in different measurement systems. Don't get confused by all the numbers. For example, a hybrid tyre with the dimensions:
- 40-622 (ETRTO)
- 28x1.5" (English inch measurement in metric notation)
- 700x38C (French size)
is one and the same tyre – an approx. 40 mm wide tyre in the 28 inch wheel size.
The air pressure specifications are from/to specifications that you should never exceed. However, you can experiment carefully with slightly less air pressure to achieve better damping. The risk of possible rim damage (punctures) or premature ageing of the tyre (cracks in the sidewall) is of course your own responsibility.
There are several system-related reasons for the different levels of wear – which indeed applies to all bike tyres:
- Weight distribution: There is always more weight on the rear wheel than on the front wheel.
- Due to the drive via the rear wheel, drive influences have a greater effect here.
- When braking, the rear wheel tends to block and/or slip.
It is therefore quite normal for the rear tyre to wear out more quickly. Road and hybrid tyres often get an angular appearance then. In this case, you should replace the tyre and not make the mistake of swapping the front and rear tyres.
