Key Factors to Consider

Terrain: Softer surfaces (e.g., loose gravel, mud, or sand) benefit from lower tire pressures for better traction.

Rider Weight: Heavier riders typically need higher pressure to prevent tire deformation and pinch flats.

Tire Width: Wider tires allow for lower pressure due to increased volume, enhancing grip and comfort.

Bike Type: Road bikes usually require higher pressure for efficient rolling on pavement, while mountain bikes prioritize traction with lower pressures on rough terrain.

Important Tips

Tubeless Tires Sealant: Tubeless systems rely on liquid sealant to fill small punctures, but sealant doesn’t hold air. It’s normal to top up tire pressure regularly.

Rim Compatibility: Always ensure your rims are compatible with tubeless tires and rated for the intended tire pressures.

Pressure Gauge: Use a high-quality pressure gauge for accuracy, especially at lower pressures where small differences can impact performance.
