Fitting and inflation tips

• Before fitting: Inspect your tyre to make sure no debris (thorns, glass, small stones) is trapped inside, to avoid any premature puncture.
  
  
• Inflation pressure: Check your tyre's sidewall, the recommended pressure is almost always marked there. For example: "Inflate to 30 psi (2.0 bar)" means the inner tube can be inflated up to 30 psi (2 bar) for optimal support.
