PSI to kPa Tire Pressure Converter
Convert your tire pressure measurement from standard Pounds per Square Inch (PSI) to kilopascals (kPa).
Quick Answer
A standard passenger car tire pressure of 35 PSI converts directly to 241 kPa (often rounded to 240 kPa on manufacturer door stickers). If your tire gauge reads in PSI but your imported vehicle manual requires 220 kPa, you need to inflate your tires to approximately 32 PSI.

Standard Tire Pressure Conversions (PSI to kPa)
| PSI | kPa | Common Application |
|---|---|---|
| 30 PSI | 207 kPa | Small cars / comfort setting |
| 32 PSI | 221 kPa | Standard passenger cars |
| 35 PSI | 241 kPa | SUVs and Crossovers |
| 40 PSI | 276 kPa | Heavy loaded SUVs |
| 50 PSI | 345 kPa | Light trucks (rear tires) |
| 80 PSI | 552 kPa | Heavy-duty trucks (max load) |
Formula
kPa = PSI × 6.89476
- PSI = Pounds per Square Inch (imperial unit)
- kPa = kilopascals (metric unit, 1,000 Pascals)
- Conversion factor = 6.89476 (exact)
- Example: 35 PSI × 6.89476 = 241.3 kPa
