1. What is the SRAM Tubeless Tire Pressure Calculator?

Definition: This calculator provides recommended tubeless tire pressures based on SRAM's pressure recommendations algorithm.

Purpose: Helps cyclists find optimal tire pressures for their weight, tire size, and riding style.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P \) — Tire pressure (psi)
• \( W \) — Combined rider and bike weight (kg)
• \( T \) — Tire width (mm)
• \( F \) — Riding style factor

Explanation: The formula calculates base pressure then adjusts for riding style and converts to psi.

3. Importance of Proper Tire Pressure

Details: Correct pressure affects traction, rolling resistance, puncture protection, and ride comfort.

4. Using the Calculator

Tips: Enter your total weight (rider + bike), actual tire width (not labeled size), and select your riding style.

5. Frequently Asked Questions (FAQ)

Q1: Why multiply by 100 in the formula?
A: This converts the result from bar to psi (1 bar ≈ 14.5 psi).

Q2: Should I run the same pressure front and rear?
A: Typically run 1-3 psi less in the front for better traction.

Q3: How does tire casing affect pressure?
A: Reinforced casings may need 2-3 psi less than lightweight casings.

Q4: When should I adjust from the recommended pressure?
A: Adjust for conditions: lower for loose terrain, higher for pavement.

Q5: Does this work for plus-sized tires?
A: Yes, but pressures will be much lower (often 15-25 psi range).
