47 psi · 324 kPa · not a second factory sticker
225/75R16C · 47 psi · 3.24 bar · 324 kPa — estimates. Placard wins.
European stickers print bar. 225/75R16C often sits near 3.24 bar on a C-type van (47 psi / 324 kPa). 3.24 bar is not “47 divided by ten”. TPMS typically warns near 35 psi (about 25% below a 47 psi target). That is already a soft tyre. 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.
Bar, PSI and kPa
Convert around the 225/75R16C band. 3.24 bar is about 47 psi — not 23, not 33 unless the maths says so.

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.
| Condition | Front (est.) | Rear (est.) |
|---|---|---|
| Driver only / unladen | 47 psi / 3.24 bar / 324 kPa | 51 psi / 3.52 bar / 352 kPa |
| Typical occupancy | 47 psi / 3.24 bar / 324 kPa | 52 psi / 3.59 bar / 359 kPa |
| Payload / towing (sketch) | 48 psi / 3.31 bar / 331 kPa | 57 psi / 3.93 bar / 393 kPa |
Placard versus sidewall
If a forum says “all 225/75R16C run 47 psi”, ignore it. A Qashqai and a Golf can share a size and not share a sticker.
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.

How to set 225/75R16C
- Park so the 225/75R16C tyres are cold (three hours, or less than about a mile).
- Read the door-pillar placard for that car — not the 225/75R16C sidewall maximum.
- If the sticker is missing, 47 psi / 3.24 bar is only a C-type van planning figure for this size.
- Set all four with a calibrated gauge. A 3 psi miss on one corner shows up as a wander.
- Refit valve caps and reset TPMS if the handbook asks for a relearn.
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 |
If the door sticker and this 225/75R16C page disagree, the sticker wins.
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.
What PSI should 225/75R16C tyres be?
A C-type van planning figure is about 47 psi cold (3.24 bar / 324 kPa). Confirm on the vehicle placard — two cars can share 225/75R16C and not share a sticker.
When does TPMS warn on 225/75R16C?
Direct TPMS typically flags about 25% below target — near 35 psi if you were aiming at 47. Fill to the sticker, not to the lamp.
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.
