Road Bike Tires: Tubeless or Traditional with Tube?

The choice of road bike tires can have a significant impact on riding performance and overall experience. Two common options are tubeless tires and traditional tires with a tube. Both have their pros and cons, affecting various factors such as weight, rolling resistance, handling, and puncture protection. In this article, we take a closer look at these two alternatives and help you make the best choice for your needs.


1. Weight


Tubeless:

A tubeless tire does not require an inner tube, which slightly reduces the overall weight of the bike. However, a tubeless tire typically has a stronger sidewall, making it heavier compared to a foldable tire model. The weight saved from the inner tube can create a noticeable difference, as it is located on the outside of the wheel, increasing the moment of inertia. This weight-saving is especially noticeable with wider tires, such as those used on gravel bikes.


Traditional with Tube:

Tires with tubes are generally slightly heavier overall because the tube adds extra weight. In the case of wider tires, such as those used on gravel bikes, the weight of the tube becomes more significant, leading to a larger difference between tubeless and traditional tires. However, new very light tubes made of TPU (thermoplastic polyurethane) have somewhat reduced the weight advantage of tubeless tires. Additionally, the sealant used in tubeless tires also contributes to the overall weight.


Conclusion Weight:

For cyclists looking to optimize weight, tubeless tires are generally a good choice due to the absence of a tube. However, the weight difference can be less significant with wider tires, as new lightweight TPU tubes reduce the gap, and the sealant in tubeless tires adds weight, which may weaken the advantage of tubeless in certain applications.


2. Rolling Resistance


Tubeless:

Tubeless tires generally offer lower rolling resistance compared to traditional tires with a tube. This is because the tire directly contacts the rim, with less friction between the tube and the tire. Modern tubeless tires are particularly efficient in this regard and provide improved performance by rolling with less internal friction. Tubeless tires can also be ridden at lower pressures, further improving rolling resistance.


Traditional with Tube:

Tires with tubes tend to generate slightly more rolling resistance, as the tube constantly makes contact with the rubber wall inside the tire, adding extra friction. This leads to a small loss of energy and slightly lower efficiency while riding.


Conclusion Rolling Resistance:

Tubeless tires provide lower rolling resistance compared to traditional tires with tubes and are therefore a better choice for those prioritizing performance.


3. Handling and Sealant of Tubeless Tires


Tubeless:

Handling tubeless tires can initially be a bit unfamiliar. The tire needs to be filled with sealant, which can quickly seal small punctures. However, this also means that regular top-ups are necessary, and there is a certain amount of maintenance required, especially if the sealant dries out or fails to work properly. Mounting a tubeless tire can also be a bit more complex, requiring rims that are compatible with tubeless systems.


Traditional with Tube:

Handling traditional tires is generally easier, as they do not require additional steps like filling with sealant. Mounting is simpler, and in case of a flat, the tube can be quickly replaced. Less maintenance is required, which is particularly advantageous for less experienced cyclists or those who prefer quick repairs.


Conclusion Handling:

Traditional tires with tubes are easier to handle, while tubeless tires require regular maintenance and special preparation. However, the sealant in tubeless tires can be a benefit when it comes to quickly fixing small punctures.


4. Puncture Protection


Tubeless:

Puncture protection is the greatest advantage of tubeless tires. The sealant inside the tire can automatically seal small punctures and holes without causing an immediate loss of air. This means fewer flat tires and less downtime during the ride. In many cases, a tubeless tire can be considered almost puncture-proof, especially on rough roads or off-road tours.


Traditional with Tube:

Traditional tires with tubes are more susceptible to punctures, as a hole in the tire or tube immediately leads to a loss of air pressure. While puncture-resistant tubes can be used with traditional tires, the overall puncture protection is lower compared to tubeless tires. In the case of a cut or sharp object in the tire, the tube will generally be damaged quickly.


Conclusion Puncture Protection:

Tubeless tires provide significantly better puncture protection, as small holes are automatically sealed as long as the sealant hasn't dried out. Traditional tires with tubes have lower puncture protection and require quick repairs.


Conclusion: Tubeless or Traditional with Tube?

The choice between tubeless and traditional tires depends on individual priorities and riding style:


  • For maximum performance, lower rolling resistance, and better puncture protection, tubeless tires are the better choice. They offer an improved riding experience but are slightly more demanding to handle and require regular sealant maintenance.

  • For easier handling and less maintenance, traditional tires with tubes are an excellent choice. They are simpler to mount and repair but offer slightly higher puncture susceptibility and rolling resistance.


Ultimately, the decision depends on which aspects are most important to you as a cyclist: the performance and puncture protection of tubeless tires or the ease of handling and lower weight of traditional options.


By the way: At Vélobsessive, all wheels are tubeless-ready, meaning you have the freedom to choose between both options.
