## What is TireCalc?

Calculate optimal bike tire pressure — science-based, instant results, no account needed.

SCIENCE-BASED
TireCalc uses the Berto/Adams formula, the industry reference for tire pressure calculation. Separate front and rear results
based on your bike type's weight distribution. Transparent methodology — no black box.

ALL FACTORS CONSIDERED
• 4 bike types: Road, Gravel, MTB, Fat Bike
• 3 tire types: Clincher, Tubeless (−12%), Tubular (−5%)
• 2 rim types: Hooked & Hookless (ETRTO limit)
• 5 surfaces: Smooth to offroad
• Wet conditions: −5% pressure correction for better grip
• Weight from 40–150 kg / 88–330 lbs

SAFETY WARNINGS
•  Hookless rim: Auto-capped at 5 bar (72 PSI) per ETRTO standard
•  Pinch-flat risk: Warning when pressure is too low with inner tubes
•  Safety limits per bike type

UNITS YOUR WAY
Pressure in bar or PSI, weight in kg or lbs — tire width auto-adjusts (mm/inches by bike type).
