235/65R16C
46 psi / 3.17 bar
317 kPa · estimates for this size class
235/65R16C · 46 psi · 3.17 bar · 317 kPa — estimates. Placard wins.
Searches for “235/65R16C pressure” usually want a number. Use 46 psi (3.17 bar) only as a sketch; the door-pillar placard on the car that wears this size still wins. Under-inflation cooks the shoulders of a 235/65R16C; 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.
What 235/65R16C means
A 235/65R16C on a C-type van is a geometry. Two cars can share the size and disagree on PSI because mass and axle split differ.
Loaded large van. Rim diameter 16 in; section 235 mm. Estimates on this page assume a typical load index for the C-type van class.
Estimated 235/65R16C pressure by load
Load moves the rear first on a C-type van. If the factory placard already has a laden column, use that — not this sketch for 235/65R16C.
| Condition | Front (est.) | Rear (est.) |
|---|---|---|
| Driver only / unladen | 46 psi / 3.17 bar / 317 kPa | 49 psi / 3.38 bar / 338 kPa |
| Typical occupancy | 47 psi / 3.24 bar / 324 kPa | 51 psi / 3.52 bar / 352 kPa |
| Payload / towing (sketch) | 48 psi / 3.31 bar / 331 kPa | 56 psi / 3.86 bar / 386 kPa |
PSI, bar and kPa
Convert around the 235/65R16C band. 3.17 bar is about 46 psi — not 23, not 33 unless the maths says so.
| PSI | Bar | kPa |

| 42 | 2.90 | 290 |
| 43 | 2.96 | 296 |
| 44 | 3.03 | 303 |
| 45 | 3.10 | 310 |

Placard versus sidewall
The sidewall of a 235/65R16C 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.

How to set 235/65R16C
- Park so the 235/65R16C tyres are cold (three hours, or less than about a mile).
- Read the door-pillar placard for that car — not the 235/65R16C sidewall maximum.
- If the sticker is missing, 46 psi / 3.17 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 46 psi as a 20 °C baseline for 235/65R16C.
| Ambient | Gauge | Bar | kPa | Note |
|---|---|---|---|---|
| −5 °C (hard frost) | 43 psi | 2.96 bar | 296 kPa | Gauge reads low; do not overfill once warm |
| 0 °C | 44 psi | 3.03 bar | 303 kPa | Gauge reads low; do not overfill once warm |
| 8 °C (UK winter morning) | 45 psi | 3.1 bar | 310 kPa | Gauge reads low; do not overfill once warm |
| 20 °C (set cold here) | 46 psi | 3.17 bar | 317 kPa | Baseline for this size sketch |
| 30 °C | 48 psi | 3.31 bar | 331 kPa | Do not bleed a hot 235/65R16C |
| 38 °C (heatwave tarmac) | 49 psi | 3.38 bar | 338 kPa | Do not bleed a hot 235/65R16C |
A cheap gauge and a monthly habit will do more for a set of 235/65R16C than nitrogen upsells.
Questions about 235/65R16C
Is 235/65R16C 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.
When does TPMS warn on 235/65R16C?
Direct TPMS typically flags about 25% below target — near 35 psi if you were aiming at 46. Fill to the sticker, not to the lamp.
What PSI should 235/65R16C tyres be?
A C-type van planning figure is about 46 psi cold (3.17 bar / 317 kPa). Confirm on the vehicle placard — two cars can share 235/65R16C and not share a sticker.
Is the sidewall number correct for 235/65R16C?
No. Sidewall PSI or kPa is a maximum for the carcass. Operating pressure is the door-pillar placard.
