👉 The wheel fluid, also known as the tire fluid or brake fluid for wheels, is a specialized liquid used to lubricate and protect the components of a vehicle's wheels and associated systems. It helps reduce friction between the wheel hubs and the wheel studs or bolts, ensuring smooth rotation and extending the life of the wheel bearings and seals. Additionally, wheel fluid acts as a barrier against contaminants like dirt and debris, preventing them from damaging the delicate components of the wheel assembly. It is essential for maintaining optimal performance and safety, especially in wet or dusty conditions, by providing a protective layer that enhances the durability of the wheel and its mounting system.
