[Notice before purchase] The luggage wheel cover is suitable for both dual-wheel and single-wheel luggage; for any diameter wheels, simply connect 2 pieces of protectors; please refer to the fourth and fifth image on the left for the width of the wheel and space between the wheels and mudguards. [Protect luggage wheel / reduce noise / shock absorption] Luggage wheel protector covers protect the wheels from wear and scratches on uneven roads with stones, bricks, or nails; it can reduce noise and provide shock absorption during luggage towing, especially in waiting halls where quiet operation is needed. [Wear resistant / anti falling off] Made from high-purity real silicone material, the luggage wheel protective cover is highly wear-resistant. Waterproof adhesive is used, ensuring the cover stays in place even on damp roads. After testing, the wheel protector was installed on luggage and dragged over stone and gravel roads for 5 kilometers without breaking or falling off. [Deeper and thicker wheel patterns] Compared to other suitcase wheel covers, the grooves on our silicone wheel protectors are deeper and thicker, enhancing wear resistance and making them suitable for rough roads.
