Maintenance and upkeep of a vehicle's wheels and tyres to ensure optimal performance, safety, and longevity. This involves tasks like regular cleaning to remove brake dust and grime, checking tyre pressure and tread depth, rotating tyres for even wear, and inspecting for damage like cuts or bulges. It also includes the use of products like tyre dressings to protect and enhance the appearance of tyres, and wheel cleaners to maintain the finish of the wheels. Proper wheel and tyre care contributes to a smooth and safe driving experience, extends the lifespan of these components, and maintains the vehicle's overall appearance.
