The right tires for your bike: an important factor for riding enjoyment, performance and safety!

In this category you will find a wide selection of tires, tubes from brands such as Continental, Panaracer, Schwalbe, WTB or HALO for your bike and accessories such as rim tape and valve extensions. Tires play a particularly important role on a bicycle. They create the contact between the bike and the surface you are riding on and therefore have a particularly large influence on riding enjoyment, performance, comfort and, of course, safety. A bad bicycle tire slows you down and a good one can really give you wings. There is a lot to consider with bicycle and road bike tires. The most important thing is the correct size, which depends on the rims and the frame. In our range, most tires have 700c or 622c which is the most common size and is also known as 28". 622 describes the inner diameter of the tire in millimeters and 700 the outer diameter. However, the outside diameter is a less important and imprecise indication of a tire, as it is influenced by width and other factors. The second indication on a tire is the width in millimeters and would be 622x28c for a 28mm wide tire, for example.  Classic road bike tires are usually between 20 and 30mm wide, whereas gravel and touring tires are usually between 35 and 45mm. In addition to the correct dimensions, there are now countless rubber compounds, tire profiles and tire constructions from the various manufacturers of bicycle tires that have a major influence on the properties of a tire. Significant properties that are influenced by this are grip, weight, rolling resistance, puncture resistance and durability on different surfaces.

Finding the dimensions on the tires and the right tire size for your rims - a short excursion into tire science!

Whether clincher, folding or tubeless tires - on current tires you will often find information from up to three sizing systems: the French system, the inch-based system and the much more precise E.T.R.T.O system. There are historical and national reasons for the existence of the different measurement systems. These different national measurement systems once ensured that the same tire size was known under different numerical designations in different countries. As a result, tires of different sizes were produced in different countries under the same size designation, which were not compatible with each other! The "classic" standards for tire sizes, the French and the inch-based system, are based on the outer diameter of the tire and are specified in inches (e.g. 26 inches or 28 inches) or millimetres (650, 700). The International Standardization Organization (ISO for short) has adopted a more universal system, the E.T.R.T.O (European Tyre and Rim Technical Organization) system based on a standardized specification according to ISO 5775 for the uniform marking of bicycle tires and rims. The ETRTO system uses only 2 numbers based on the width of the tire and most importantly - the inner diameter of the tire matching the outer diameter of the rim.

The oldest sizing system for tires is French. Originally developed in the motherland of bicycle racing, the French designation is composed as follows: a three-digit number indicating the approximate outer diameter of the tire in millimeters, a multiplication sign, a two-digit indication of the tire width in millimeters and a letter. This may look like this: 700x25C. The letter should give an indication of the recommended inner rim diameter and the tire height. A = narrow to D = very wide. In the meantime, however, the letter no longer says much about the actual width, as current 700C road bike tires, for example, are rather narrow and are ridden on correspondingly narrow rims, but wide twentyniner MTB tires also have a 700C specification in the French system and are sometimes also ridden on 40 mm wide rims.

In the inch-based system, one inch corresponds to 25.4 mm. The inch specification can be written after the decimal point in decimal (e.g. 29 x 2.40 inches) or as a fraction (e.g. 28 x 1 1/2 inches). The first value refers to the approximate outer diameter of the tire and the second usually refers to the width of the tire. In the case of a three-part inch specification in fractional notation such as 28" x 1 5/8" x 1 3/8", the second value stands for the height and the last for the width. There are multiplication signs between the values. When cyclists talk about 26" or 29", they are always referring to the first value of the inch specification. In reality, the outer diameter rarely corresponds to the actual diameter required. The reason for this is the wide range of widths and the inner rim diameter - 29 inch tires are ultimately just very wide 28 inch tires and also fit on wheels that are listed as 28 inch. You should also be careful when converting a fractional tire size, e.g. from a Dutch bike or old touring bike tire. After measuring, you will most likely choose a model with a different inner diameter.

The system of the European Tyre and Rim Technical Organization is based on the international standard ISO 5775 for the uniform marking of bicycle tires and rims. The specification is in millimetres and can look like this, for example: 43-584. The first specification stands for the tire width and is often measured at the widest point of the carcass. The result can vary depending on the rim and air pressure of the same tire. The second, three-digit number after the slash stands for the tire's inner diameter. This corresponds to the diameter of the rim at the tire seat. Your tire will therefore fit reliably on your wheel or rim ring if the 3-digit E.T.R.T.O specification is the same.
