Enter your rider weight, bike weight, tire widths, and tube type — we'll calculate the optimal PSI for your front and rear tires based on contact patch science.

Book a ServiceOver-inflated tires skip off surface imperfections, increasing vibration and actual rolling resistance. Optimal pressure maximizes the tire's ability to deform and conform to the road.
Too low and clincher tubes pinch between rim and obstacle — a "snakebite" flat. Tubeless setups eliminate this risk entirely, which is why they run notably lower pressures.
Weight-matched pressure ensures the contact patch is the right size — enough to absorb vibration without the tire squirming under hard cornering loads.
Methodology: Pressures are calculated using contact-patch theory: front load = 40% / rear load = 60% of total system weight, scaled by tire width using an empirical constant derived from published tire manufacturer data. Tube-type multipliers reflect the compliance characteristics of each material (butyl 1.0×, TPU 0.95×, latex 0.90×, tubeless 0.83×). Tire category multipliers reflect casing stiffness (TPI): race 0.93×, performance-comfort 0.97×, training 1.0×, budget 1.05×. Results are a starting point — fine-tune ±5 PSI based on feel, surface conditions, and tire manufacturer minimums.
