Recommended tyre pressure for general riding is:
Under 10 years old 25 - 30psi
Over 10 Years Old 40 - 45psi
Some tyres will have a maximum of 65 psi, whilst the tyres are designed strong enough to handle this pressure, the bikes are designed to operate at the recommended pressures to allow extra clearance with the chain and brake caliper.
