Mountain Bike Tire Standards and Common Misconceptions
Tire Pressure and Material are Key, Scene Adaptation Prevents Risks
The performance of bicycle tires directly affects riding efficiency and safety. The "Bicycle Tire Quality Evaluation Standard" published by the China Bicycle Association shows that improper tire pressure and inferior materials are the main causes of tire blowouts and skidding, accounting for 42% of riding accidents. The following points should be considered when purchasing and using tires:
Tread Pattern Selection Based on Scene: The common misconception that "slick tires (shallow tread tires) are unsafe in the rain" is incorrect. Tests show that shallow tread tires with silicone anti-slip material have a 15% shorter braking distance in the rain than inferior deep tread tires. For city commuting, choose 28-32mm wide shallow tread tires for a balance of efficiency and anti-slip performance; mountain biking requires 2.2-2.5 inch deep tread tires to enhance grip on complex terrain; competition-grade ultra-narrow tires (<23mm) are only suitable for dry tracks and are not recommended for daily use.
Tire Pressure Control Standards: Strictly inflate tires according to the pressure range marked on the sidewall. The optimal range is 4-6 bar for commuter bikes, 3-5 bar for mountain bikes, and 8-10 bar for road bikes. Tests show that when tire pressure is 30% below the standard value, riding resistance increases by 25%; when it is 20% above the standard value, the risk of blowout increases threefold. In summer, an additional 0.5 bar reduction is needed to prevent blowouts due to thermal expansion.
Lifespan Check Determines Replacement: Tires should adhere to a "3 years/5000 kilometers" dual standard. Even with minimal wear, rubber will age and crack after 3 years. Tires must be replaced when the tread depth is less than 1.6mm to avoid skidding or punctures in wet conditions.
