44 psi · 303 kPa · not a second factory sticker
215/70R15C · 44 psi · 3.03 bar · 303 kPa — estimates. Placard wins.
A 215/70R15C C-type or LT carcass can live far above a hatchback bar figure. This page’s 3.03 bar sketch is for the C-type van class, not every car that can physically mount the tyre. Under-inflation cooks the shoulders of a 215/70R15C; over-inflation wears the centre rib and bangs every cat’s eye. 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 215/70R15C band. 3.03 bar is about 44 psi — not 23, not 33 unless the maths says so.

| 2.76 | 40 | 276 |
| 2.83 | 41 | 283 |
| 2.90 | 42 | 290 |

Estimated 215/70R15C pressure by load
Plus-sizing to 215/70R15C from a taller OEM tyre usually keeps the same placard if the load index is equal or higher.
| Condition | Front (est.) | Rear (est.) |
|---|---|---|
| Driver only / unladen | 44 psi / 3.03 bar / 303 kPa | 47 psi / 3.24 bar / 324 kPa |
| Typical occupancy | 45 psi / 3.1 bar / 310 kPa | 49 psi / 3.38 bar / 338 kPa |
| Payload / towing (sketch) | 46 psi / 3.17 bar / 317 kPa | 54 psi / 3.72 bar / 372 kPa |
Placard versus sidewall
The sidewall of a 215/70R15C may say 51 psi or 350 kPa. That is a carcass maximum. Operating pressure is the tyre-information placard on the driver’s door pillar.
What 215/70R15C means
A 215/70R15C on a C-type van is a geometry. Two cars can share the size and disagree on PSI because mass and axle split differ.
15-inch van C-type. Rim diameter 15 in; section 215 mm. Estimates on this page assume a typical load index for the C-type van class.

How to set 215/70R15C
- Measure before the school run, not after the motorway.
- Write LF / RF / RR / RL. Do not keep 215/70R15C numbers in your head.
- Add air in short bursts toward the placard, using 44 psi only as a map.
- If one 215/70R15C 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 44 psi as a 20 °C baseline for 215/70R15C.
| Ambient | Gauge | Bar | kPa | Note |
|---|---|---|---|---|
| −5 °C (hard frost) | 41 psi | 2.83 bar | 283 kPa | Gauge reads low; do not overfill once warm |
| 0 °C | 42 psi | 2.9 bar | 290 kPa | Gauge reads low; do not overfill once warm |
| 8 °C (UK winter morning) | 43 psi | 2.96 bar | 296 kPa | Gauge reads low; do not overfill once warm |
| 20 °C (set cold here) | 44 psi | 3.03 bar | 303 kPa | Baseline for this size sketch |
| 30 °C | 46 psi | 3.17 bar | 317 kPa | Do not bleed a hot 215/70R15C |
| 38 °C (heatwave tarmac) | 47 psi | 3.24 bar | 324 kPa | Do not bleed a hot 215/70R15C |
If the door sticker and this 215/70R15C page disagree, the sticker wins.
Questions about 215/70R15C
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.
Can I run 215/70R15C at a lower pressure for comfort?
Not as a habit. A soft 215/70R15C cooks the shoulders and dulls steering. Keep load index and stay on the placard.
Is 215/70R15C 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.
When does TPMS warn on 215/70R15C?
Direct TPMS typically flags about 25% below target — near 33 psi if you were aiming at 44. Fill to the sticker, not to the lamp.
What PSI should 215/70R15C tyres be?
A C-type van planning figure is about 44 psi cold (3.03 bar / 303 kPa). Confirm on the vehicle placard — two cars can share 215/70R15C and not share a sticker.
