Convert tire pressure: bar, PSI, kPa
Tire pressure in different units for car, motorcycle, bicycle:
- bar: Standard in Europe (1 bar = 100,000 Pa)
- PSI: Pounds per square inch (USA, UK)
- kPa: Kilopascal (SI unit)
- Conversion: 1 bar = 14.5 PSI = 100 kPa
Typical values:
- Passenger car: 2.0-2.5 bar (29-36 PSI) front/rear
- Transporter: 2.5-4.0 bar (36-58 PSI) loaded
- Motorcycle: 2.25-2.9 bar (33-42 PSI)
- Bicycle (trekking): 3.5-5.0 bar (50-70 PSI)
- Road bike: 7-9 bar (100-130 PSI)
- MTB: 2-4 bar (29-58 PSI)
Important: Measure tire pressure when cold! Pressure increases by 0.3 bar while driving. Too low pressure: higher consumption, wear. Too high: poor grip, harsh ride comfort.
Check: At least once a month and before long journeys. Values in the door handle or fuel filler cap.
