How It Works

Higher pressure does NOT always mean faster. Research shows that on real roads, slightly lower pressures (matching 15% tire drop under load) are fastest due to better vibration absorption. The rear tire carries 60% of the weight — it needs more pressure. Front tire gets 10-15% less than rear. Tubeless tires can safely run 5-10 psi lower because there is no pinch-flat risk. Wider tires need less pressure: 23mm = 90-110 psi, 25mm = 75-95 psi, 28mm = 65-85 psi, 32mm = 50-70 psi, 40mm+ = 35-50 psi.
