You want to determine the bicycle tire size?
Tires are flat again and again and now buy a tire with puncture protection?
Or put on a wider tire?
Find the right tire now!
All you need is the bike tire designation on the bike casing.
|42-622||Tire width 42 mm, tire inner diameter 622 mm (ETRTO standard)|
|28x1.60||Tire outer diameter 28", tire width 1.60" (ca. 41 mm) (English designation)|
|700x40C||Tire outer diameter 700 mm, tire width 40 mm, tire height C = ca. 39 mm (French designation)|
If the tube has a hole on the outside of the wheel, toward the casing, a common cause is a sharp object, such as a shard of glass or piece of wire, that first drilled through the casing and caused the hole in the tube. The sharp object usually falls off again and can no longer be seen later.
For me, putting on puncture protection tires, which are tires with an extra protective layer underneath the tread, worked wonders and permanently solved the problem. Pay attention to the column puncture protection level in the table above.
The puncture protection level indicates how strongly the tire protects against sharp objects. Thereby a higher number means a higher puncture protection. To explain the numbers, I refer to the puncture protection of Schwalbe tires (see the references below). I have deliberately omitted values smaller than 4, because in my opinion they have too little protective effect.
Occasionally, tires are understood to be the combination of a casing and an inner tube. On this web page, however, I make no distinction and use both terms synonymously.
The best way to replace the tire with a new one of the same size is to type in the label on the tire above and pay attention to the dimensions shown, then you'll be on the safe side. However, depending on your riding speed and trail conditions, different tire widths and air pressure may be more comfortable. Here you can vary a bit if you are dissatisfied with the driving behavior of your bike.
Advantages of folding bead tires: The ordinary wire bead tire has rigid metal wires in the bead core, which rests against the rim. The folding bead tire, also foldable tire, on the other hand, contains a synthetic fiber and thus has a lower weight. In addition, folding bead tires are easier to carry in the backpack as spare tires.
Disadvantages of folding bead tires are the higher price and that they require more skill to mount, because they do not take a round shape by themselves.
The bike tires usually have a designation written on the casing. The easiest and most effective solution is to write those numbers in the search input field above and press the search button. You will see an explanation of your tire designation and a list of matching tires.
