Configuració i instal·lació
Proper installation of motorcycle tires is crucial for safety and performance. It is highly recommended that tire installation be performed by a qualified professional using appropriate tools and techniques.
Comprovacions prèvies a la instal·lació:
- Inspect the Tire: Before mounting, carefully inspect the tire for any manufacturing defects, damage, or foreign objects.
- Rim Compatibility: Ensure the tire size (190/50ZR17) is compatible with your motorcycle's rim specifications. Refer to your motorcycle's owner's manual for recommended tire sizes.
- Tija de la vàlvula: Always replace the valve stem when installing a new tire to ensure proper sealing and prevent air leaks.
- Fletxes direccionals: Note any directional arrows on the tire sidewall. Tires must be mounted to rotate in the indicated direction.
Mounting Procedure (Professional Recommended):
- Clean the rim thoroughly, removing any old rubber residue or corrosion.
- Apply appropriate tire mounting lubricant to the tire beads and rim flanges.
- Carefully mount the tire onto the rim, ensuring the beads seat correctly.
- Inflate the tire to the recommended seating pressure, listening for the beads to seat with an audible pop. Do not exceed maximum seating pressure.
- Once seated, adjust the tire pressure to the motorcycle manufacturer's recommended cold inflation pressure. This information is typically found on a sticker on the swingarm, frame, or in the owner's manual.
- Balance the wheel and tire assembly using a suitable balancing machine.
Important: Incorrect tire mounting can lead to tire failure, loss of control, and serious injury. If you are unsure, seek professional assistance.
Pautes de funcionament
Proper operation and maintenance are essential for maximizing tire life and ensuring rider safety.
Pressió dels pneumàtics:
Maintain correct tire inflation pressure as specified by the motorcycle manufacturer. Check tire pressure when tires are cold (before riding). Under-inflation can lead to excessive heat buildup, premature wear, and potential tire failure. Over-inflation can reduce the tire's contact patch, affecting grip and ride comfort.
Període d'entrada:
New tires require a break-in period, typically around 100 miles (160 km). During this period, avoid sudden acceleration, hard braking, and aggressive cornering. This allows the tire's surface to scuff in and the components to settle, providing optimal grip.
Capacitat de càrrega:
Do not exceed the maximum load capacity indicated on the tire sidewall. Overloading can cause excessive heat buildup and tire failure.
Classificació de velocitat:
The BT-021-U has a speed rating of 'W' (168 mph / 270 km/h). Do not exceed the tire's maximum speed rating or the motorcycle's maximum speed, whichever is lower.
Manteniment
Regular inspection and maintenance will prolong the life of your Bridgestone Battlax tire.
Comprovacions periòdiques:
- Pressió dels pneumàtics: Check cold tire pressure at least once a week and before every long ride.
- Profunditat de la banda de rodament: Inspect tread depth regularly. Replace the tire when the tread wears down to the wear indicators (typically 0.8mm for motorcycles).
- Inspecció de danys: Visually inspect the tire for cuts, punctures, bulges, cracks, or any signs of impact damage. If damage is found, have the tire inspected by a professional immediately.
- Valve Caps: Ensure valve caps are always in place to prevent dirt and moisture from entering the valve stem.
Neteja:
Clean tires with mild soap and water. Avoid using petroleum-based cleaners or tire dressings, as these can degrade the rubber compounds.
Emmagatzematge:
If storing the motorcycle for an extended period, ensure tires are properly inflated and ideally off the ground to prevent flat spots. Store in a cool, dry place away from direct sunlight and ozone-producing equipment.
