Comparison of Water Discharge Performance of Motorcycle Tires with Different Tread Patterns by Applying CFD (Computational Fluid Dynamics) Technique

Abstract

The tire is one of the most important vehicle parts that provide contact between the vehicle and the road surface together with the air it carries in it. Some traffic accidents are due to driving performance on the wet road surface. Aquaplaning on water occurs when depressions and sloping areas on the asphalt become filled with water, causing it to accumulate. When a vehicle passes over a puddle, its tires lose contact with the ground, causing it to slide instead of tire pattern channels helping roll on the water. This can cause problems with water drainage. When a vehicle passes over a puddle, its tires lose contact with the ground, causing it to slide instead of roll on the water. This can cause problems with water drainage. For this reason, it is extremely important to design the pattern on the tires properly. The pattern channels on the tire help to evacuate water by passing it through the channels formed on the asphalt surface. However, in cases where the amount of water is high, the pattern channels will be forced after a while and lose contact with the ground, as they cannot discharge all the water bodies. For this reason, it is extremely important to design the pattern on the tires properly. The study analyzed the water evacuation effects of motorcycle tires with three different tread patterns on wet surfaces, taking into account different factors such as contact angles, driving direction, and driving speeds. The data obtained from the study indicate that the tread pattern design has a significant impact on the aquaplaning performance of tires on water surfaces.
