What are the recommended psi levels for optimal performance on a mountain bike?

The recommended psi levels for optimal performance on a mountain bike vary depending on factors such as rider weight, terrain, tire width, and personal preference. As a general guideline, most mountain bike tires are typically inflated between 25-35 psi for optimal performance. Riders may need to adjust the psi levels based on their specific riding conditions and preferences to achieve the best balance of traction, control, and efficiency. It is recommended to experiment with different psi levels to find the ideal setting for your riding style.
