Bike Pressure Calculator Pro
PSI & Bar: Road, MTB, Gravel
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Most cyclists ride on the wrong tire pressure - quietly losing watts, grip, and comfort with every pedal stroke.
Bike Pressure Calculator Pro gives you the exact PSI and bar values for your weight, tire width, terrain, weather, and wheel setup. In seconds. No guessing. No generic charts.
WHAT IT CALCULATES
A physics-based formula accounts for every factor that matters:
- Rider & bike weight — more precise than any generic chart
- Bike type — road, TT, gravel, MTB, or urban
- Tire width & wheel diameter — auto-detects road, gravel, and MTB zones
- Surface type — from smooth asphalt to rough gravel and dirt
- Weather — adjusts for temperature and humidity
- Altitude — corrects for pressure loss at high elevations
- Wheel material — carbon or aluminum
- Contact patch & weight distribution — separate values for front and rear
FEATURES
- PSI and bar output for both tires simultaneously
- Results update instantly as you change any setting
- Save multiple bike profiles
- Monthly reminder to recheck pressure
- Fully offline — works anywhere, no signal required
- Clean UI built for real rides
WHY PRESSURE MATTERS
Correct PSI means fewer watts wasted, better traction on every surface, longer tire life, and a noticeably smoother ride. A small adjustment with a measurable impact — whether you race, train, or just enjoy the road.
