Bike Tires – A Comprehensive Guide to Choosing Tires!

17.2.2025

Bicycle tires have a huge impact on riding comfort, traction, and performance. Choosing the right outer tire depends on the type of riding, the surface, and the features you value most. In this guide, we'll go over the key things to consider when choosing new bike tires!

1. For what purpose do you need tires?
  • Road cycling: Fast and lightweight tires with low rolling resistance.
  • Gravel & adventure: Versatile tires with more grip and puncture protection.
  • Mountain biking: Rough-pattern tires that provide maximum grip on various surfaces.
  • City & commuting: Durable and puncture-protected tires with good rolling and comfort.

 


 

2. Tire size – how to choose the right one?

Tire size is usually indicated in two ways: in millimeters (ETRTO marking, e.g., 37-622) or inches (e.g., 29” x 2.4”).

  • Inch size: A common standard used by bike type, like 26" for mountain bikes and 28" for city bikes.
  • ETRTO number: A more precise standard where the first number indicates the rim diameter in millimeters and the second the tire width. For example, 622-37 (also expressed as 37-622) means a 28" tire with a width of 37 mm.

How to choose the right size:

  • Check your current tires: You'll find the size indication on the side of your old tires.
  • Ensure bike compatibility: Not all frames support wider tires – check the maximum width!
  • Consider wider or narrower: Wider tires add comfort and grip, while narrower ones roll lighter.

Common tire sizes and uses:

  • 700c or 28" (622 mm) – Road, gravel, and hybrid bikes
  • 29” (622 mm) – Mountain and gravel bikes
  • 27.5” (584 mm) – Mountain bikes, some city bikes
  • 26” (559 mm) – Older MTB models and some city bikes

If unsure, the ETRTO marking (e.g., 37-622) is the most reliable way to find a compatible tire. The first number represents the tire width in millimeters, and the second indicates the rim diameter.

 


 

3. Tread pattern and grip – choose the right profile

  • Smooth pattern = Fast and light rolling (road & city)
  • Light tread pattern = Balance between rolling and grip (gravel)
  • Deep tread & knobs = Maximum grip on trails (MTB)

 


 

4. Tubeless or traditional?

Tubeless tires reduce the risk of punctures and offer better grip at lower pressures. Traditional tires with inner tubes are easier to install and maintain.

 


 

5. Tire pressure affects everything

The right air pressure improves rolling efficiency, comfort, and grip. Check the recommended pressure for your tires and adjust it according to riding conditions!

  • High pressure (6–8 bar): Reduces rolling resistance and boosts speed, suitable for road bikes.
  • Low pressure (2–4 bar): Increases comfort and grip, especially important for off-road riding.
  • In winter, slightly lower pressure improves tire grip on slippery surfaces.

 


 

Summary

Selecting the right bicycle tire depends on your bike type, usage needs, and the conditions you ride in. Choosing high-quality and suitable outer tires ensures comfort, safety, and performance on all surfaces.
