Why Automatic Follow Suitcases Need Grooved Tires: Solutions for Frequent Wet Conditions

Automatic follow suitcases often face slippage issues on rainy or wet surfaces. This article delves into the structural principles of grooved tires—specifically the PU tread design featuring drainage channels that effectively reduce the water film effect and enhance grip. By presenting laboratory-simulated test data comparing friction coefficients on dry and wet surfaces, it clearly illustrates the improvement in anti-slip performance. The analysis explains why this design is especially suitable for high-frequency water-exposure scenarios such as intelligent towing luggage and commercial cleaning vehicles. Readers will gain a clear understanding that not all tires perform well in humid environments and that a 'small groove' in your suitcase wheel is essential for stable movement.
