Larger tires are commonly used on motorcycles with higher engine displacements (CC) for several reasons:
Increased Load Capacity: Motorcycles with higher engine displacements generally have more power and torque, which allows them to carry heavier loads. Larger tires provide a larger contact patch with the road, which helps distribute the weight more effectively and provide better stability and handling when carrying a heavier load.
Improved Stability: Larger tires offer enhanced stability, especially at higher speeds. They have a larger surface area in contact with the road, providing better traction and grip. This can help improve overall stability and control of the motorcycle, particularly during cornering or under acceleration.
Enhanced Handling: Bigger tires can contribute to better handling characteristics. They often have a wider profile, which can result in improved cornering performance by providing a larger contact patch and more grip. This can help the motorcycle maintain better traction and control during aggressive maneuvers.
Increased Ground Clearance: Motorcycles with higher engine displacements are often designed for various riding conditions, including touring, sport riding, or off-road adventures. Larger tires can offer increased ground clearance, allowing the motorcycle to handle uneven terrain or road irregularities more effectively without the risk of hitting the ground or obstacles.
Durability and Heat Dissipation: Larger tires tend to have thicker sidewalls and more robust construction, which can improve durability and resistance to punctures or damage. Additionally, the increased volume of air within larger tires helps with heat dissipation, reducing the chances of tire overheating during prolonged and demanding rides.
It's important to note that the choice of tire size depends on various factors, including the motorcycle's design, intended use, and rider preferences. Different motorcycles may have specific tire size requirements, taking into account factors such as suspension geometry, clearance, and overall performance characteristics. Therefore, while larger tires are commonly used on motorcycles with higher engine displacements, it's essential to consult the manufacturer's recommendations and consider the specific requirements of the motorcycle in question.
