What are the best practices for maintaining and replacing tires on a mountain bike?

To maintain and replace tires on a mountain bike, it is important to regularly check tire pressure, tread wear, and overall condition. Keep tires properly inflated, rotate them regularly, and replace them when tread is worn down or there are signs of damage. Choose tires that are appropriate for the terrain you ride on and consider factors like tread pattern and width. It is also recommended to carry a spare tube and tools for quick repairs on the trail.
