Why are tubeless bicycle tires

Tubeless Tires: Advantages and Disadvantages of Tubeless Tires

According to some bicycle tire manufacturers, tubeless is the one Tire technology of the future. Impellers without tubes are particularly suitable for ambitious cyclists. We introduce the tubeless tires.

What are tubeless tires?

The English term tubeless also translates into German tubeless. Tubeless tires are therefore bicycle tires with air but without a tube. Tubeless technology for bicycles emerged from the methodology that has been used in motorcycle tires for over 30 years and even in car tires for over 60 years.

Developing tubeless tires for bicycles, however, was more of a challenge. Because the bicycle tires are very sensitively constructed and therefore essential more prone to damage by external influences. Well-known manufacturers such as Nexo and Schwalbe saw the advantages of tires without tubes. They therefore developed tubeless systems, which are now often called Mountain bike tires come into use.

The tubeless bikes are very simple. The tubeless impellers usually have the Properties of folding tires or clincher tires on. Together with the rim, they form a tight air chamber. To keep the air in the tire better, he often has a very special shape. A rim tape that is stuck to the bottom of the rim seals the tire and prevents the air from escaping through the holes for the spokes. A special tubeless valve prevents air from escaping through the hole for the valve.

Depending on factors such as the weight of the driver and road conditions Tubeless tires normally one Air pressure from 1.8 bar to 1.9 bar. The maximum air pressure for tires without a tube is 4 bar.

Sealing milk for tubeless tires

However, conventional tire jackets are rarely completely airtight. That is why tubeless tires must have a special Latex emulsion be filled. This emulsion is colloquially called Sealing milk or tubeless milk known. It automatically seals smaller holes and cuts that are not completely covered by the inner rim tape. This milk is available in different versions for holes of different sizes or especially for sealing cuts. Before making a purchase, it is definitely worth making a comparison because there are significant differences in quality.

Top up compressing milk regularly

Because the milk dries up in the tire over time, and so does hers effect loses, you should top up regularly. You can use a needle to check whether there is still active milk in the tire. Poke a hole in the tread and turn the tire. The hole usually re-densifies immediately. If that doesn't happen, you have to Refill sealing milk. The fresh emulsion closes the hole again.

If you don't mind the extra weight of milk, you can always add extra weight before a longer tour or competition Tubeless milk Add. You can then inflate the tire again with a tubeless pump or a tire booster until the desired air pressure is reached.

Mount tubeless tires yourself?

Are you thinking about converting your bike tires to tubeless? Not all tires can be converted to this system. A tubeless bicycle tires consists of a combination of individual components that must all be compatible with each other. A Tubeless tires is not suitable for all types of rims, for example.

Therefore, before assembling, find out whether a Compatibility of all items and the rims are actually tubeless-ready or tubeless-ready. Converting normal rims to tubeless rims is only recommended for real hobbyists. In addition, the Assembly of tubeless tires not that easy to do. If you need several attempts, that's no problem. There are currently no standards on the market for tires without tubes, so that each manufacturer develops its own products. This is a challenge for cyclists who repair or convert their bikes themselves.

The non-existent standards mean that components have to be compatible with one another. It starts with the rim and also applies to the rim tape. These bike parts must tubeless-ready because only with the right tubeless rim tape can the rim be really airtight at the end.

For the Conversion to a tubeless system a tubeless kit is suitable. A Kit for tubeless tires contains valves, sealing milk and assembly fluid. The liquid substance forms a lubricating film after application, so that the tire can be slipped over the rim more easily during tubeless assembly.

Advantages of a tubeless tire

Compared to tubular tires, tubeless tires have a number of useful properties:

  • lower rolling resistancebecause there is no friction between the tire and the ground
  • less weight due to the lack of the hose
  • Driving with lower air pressure is possible without greater risk of damage
  • more grip and a better driving experience due to low air pressure
  • tubeless tires repair themselves with minor damage caused by the sealing milk
  • no bursting hoses and ruptures of the valve and thus free from glitches

Disadvantages of tubeless tires

Of course, the tubeless system also has a few disadvantages compared to other bicycle tires:

  • special rims and components are necessary
  • Fitting and replacing the tires are more complex and require a lot of manual skill
  • regular Filling up the sealing milkso as not to break down while driving
  • larger obstacles can damage the rim flange if they pierce due to the low air pressure
  • If a tubeless tire slips off the rim flange and loses air, that's it Inflate often only possible with an air compressor or a special hand pump with pressure reservoir

Does it make sense to convert to tubeless tires?

To avoid breakdowns, tubeless tires are almost unbeatable. Tubeless riders swear by the MTB tires on the system. When driving off-road with lots of rubble, step on the paths often defects on. These can be achieved with tires without a tube Minimize breakdowns.

As is so often the case, whether a tubeless system is an option for you is an individual decision. A good driving experience, fewer breakdowns and low rolling resistance are convincing arguments for new tires.
