1 kPa = 0.1450 PSI · 1 PSI = 6.895 kPa · 1 bar = 100 kPa = 14.504 PSI
This tyre pressure converter makes tyre pressure conversion instant — enter any value in PSI, kPa, or bar and get the equivalent in the other units. Essential for UK, Australian, and European drivers where vehicles specify pressure in kPa (like 240 kPa) but gauges often read in PSI. Correct inflation is vital for tyre life, fuel economy, and safe handling.
PSI (Pounds per Square Inch) is commonly used in the United States, while kPa (Kilopascals) is a standard metric unit used in many other parts of the world and by vehicle manufacturers globally.
Typical recommended tyre/tire pressures by vehicle category. These are general ranges — always check your specific vehicle's doorjamb sticker or owner's manual for the correct cold inflation pressure.
| Vehicle Type | Front (PSI) | Rear (PSI) | Front (kPa) | Rear (kPa) | Notes |
|---|---|---|---|---|---|
| Compact car (e.g., VW Golf, Honda Civic) | 30–35 | 30–35 | 207–241 | 207–241 | Check doorjamb sticker |
| Midsize sedan (Camry, Accord) | 32–35 | 32–35 | 221–241 | 221–241 | Often higher in rear if loaded |
| SUV / Crossover (RAV4, CR-V) | 33–36 | 33–38 | 228–248 | 228–262 | Rear often higher for load |
| Light truck / pickup | 35–45 | 45–65 | 241–310 | 310–448 | Rear varies with payload |
| Motorcycle (typical) | 28–36 | 33–42 | 193–248 | 228–290 | Varies widely by model |
| Road bicycle | 80–130 | 80–130 | 552–896 | 552–896 | Tubeless runs lower |
| Mountain bike | 20–35 | 22–38 | 138–241 | 152–262 | Terrain dependent |
| Golf cart (standard) | 18–22 | 18–22 | 124–152 | 124–152 | Check tyre sidewall max |
| RV / Motorhome | 80–110 | 80–110 | 552–758 | 552–758 | Load-dependent; check placard |
All values are typical ranges for cold inflation pressure (tyre not driven for 3+ hours). Your vehicle's placard is the authoritative source.
- Enter the tyre pressure value you wish to convert in the 'Value to Convert' field.
- Select the direction of conversion: 'PSI to kPa' or 'kPa to PSI'.
- The converted pressure will be displayed instantly in the 'Conversion Result' section.
- Use the result to accurately inflate your tyres according to your vehicle's specifications (UK door stickers often show kPa).
What is KPA to PSI conversion formula?
To convert KPA to PSI: divide kPa by 6.895. To convert PSI to KPA: multiply PSI by 6.895. For example, 240 kPa ÷ 6.895 = 34.8 PSI, and 35 PSI × 6.895 = 241.3 kPa. Our calculator does this instantly for you!
Why do I need to convert tire pressure units?
Your car's door sticker may show tire pressure in kPa (like 240 kPa), but your tire gauge reads in PSI. Converting ensures you inflate to the exact manufacturer specification for optimal safety, fuel economy, and tire life.
What tire pressure is 35 PSI in KPA?
35 PSI equals 241.3 kPa. This is a common tire/tyre pressure for passenger cars. Many European and Asian vehicles specify this pressure in kPa on the door placard.
Is 2.2 bar the same as PSI or KPA?
2.2 bar equals 32 PSI or 220 kPa. Bar is another pressure unit (1 bar = 14.5 PSI = 100 kPa). Use our converter for instant conversions between all pressure units!
What's better for tire pressure: PSI or KPA?
Neither is 'better' - they're just different measurement units. PSI is common in the US, while kPa is used internationally. Always use the unit specified by your vehicle manufacturer for accuracy, whether it's tire or tyre pressure.
How do I read kPa pressure on my car's door sticker?
Look for numbers like '240 kPa' or '2.4 bar' on your driver's door jamb. This is your recommended cold tire pressure. If your gauge reads PSI, convert using our tool: 240 kPa = 34.8 PSI.
How do I do tyre pressure conversion from kPa to PSI?
Tyre pressure conversion from kPa to PSI is easy: divide the kPa value by 6.895. For example, 240 kPa ÷ 6.895 = 34.8 PSI. Our tyre pressure converter does this calculation instantly for accurate results every time!
What is 250 kPa in PSI?
250 kPa equals 36.3 PSI (250 ÷ 6.895 = 36.26). This is a common tyre pressure for SUVs and larger passenger vehicles. In bar, 250 kPa = 2.5 bar. Always verify the correct pressure for your specific vehicle on the doorjamb sticker.
How does bar relate to PSI and kPa for tyre pressure?
1 bar = 100 kPa = 14.504 PSI. So 2.4 bar = 240 kPa = 34.8 PSI, and 2.5 bar = 250 kPa = 36.3 PSI. Bar is commonly used on European tyre pressure gauges. Our conversion chart above shows the full range from 1.9 bar (190 kPa) to 3.1 bar (310 kPa) in PSI.
