47 psi / 3.24 bar
324 kPa · estimates for this size class
225/75R16C · 47 psi · 3.24 bar · 324 kPa — estimates. Placard wins.
Searches for “225/75R16C pressure” usually want a number. Use 47 psi (3.24 bar) only as a sketch; the door-pillar placard on the car that wears this size still wins. A 10 °C overnight drop takes roughly 1 psi (0.07 bar) off a closed 225/75R16C. C-type van tyres (the trailing C) are built for load. Copying a Golf’s 2.3 bar onto a {sz} Transit is how you cook a shoulder on the A1.
What 225/75R16C means
225/75R16C means a 225 millimetre section width, a sidewall that is 75 percent of that width, on a 16-inch rim. The R is radial construction.
Taller load-range van. Rim diameter 16 in; section 225 mm. Estimates on this page assume a typical load index for the C-type van class.
Estimated 225/75R16C pressure by load
These 225/75R16C load steps are ± a few PSI from 47. They are not a licence to ignore a printed second column on a van or estate.

How to set 225/75R16C
- Measure before the school run, not after the motorway.
- Write LF / RF / RR / RL. Do not keep 225/75R16C numbers in your head.
- Add air in short bursts toward the placard, using 47 psi only as a map.
- If one 225/75R16C is 4 psi down, hunt for a nail before you blame the weather.
- Log date, ambient temperature and the four readings.
Temperature drift
Roughly 1 psi per 5–6 °C. The table uses 47 psi as a 20 °C baseline for 225/75R16C.
| Ambient | Gauge | Bar | kPa | Note |
|---|---|---|---|---|
| −5 °C (hard frost) | 44 psi | 3.03 bar | 303 kPa | Gauge reads low; do not overfill once warm |
| 0 °C | 45 psi | 3.1 bar | 310 kPa | Gauge reads low; do not overfill once warm |
| 8 °C (UK winter morning) | 46 psi | 3.17 bar | 317 kPa | Gauge reads low; do not overfill once warm |
| 20 °C (set cold here) | 47 psi | 3.24 bar | 324 kPa | Baseline for this size sketch |
| 30 °C | 49 psi | 3.38 bar | 338 kPa | Do not bleed a hot 225/75R16C |
| 38 °C (heatwave tarmac) | 50 psi | 3.45 bar | 345 kPa | Do not bleed a hot 225/75R16C |

Questions about 225/75R16C
Is 225/75R16C the same as a plus-size swap?
Only if that is the size you fitted. Overall diameter should stay close to OEM. Pressure still follows the car, with load index at or above original.
Should I bleed pressure after a motorway run?
No. Heat raises the gauge. Set cold only. Bleeding a hot tyre leaves it low the next morning.
Is the sidewall number correct for 225/75R16C?
No. Sidewall PSI or kPa is a maximum for the carcass. Operating pressure is the door-pillar placard.
Can I run 225/75R16C at a lower pressure for comfort?
Not as a habit. A soft 225/75R16C cooks the shoulders and dulls steering. Keep load index and stay on the placard.
What is 225/75R16C in kPa?
324 kPa is the planning midpoint (100 kPa = 1 bar). 331 kPa is one PSI higher.
