235/65R16C · 46 psi · 3.17 bar · 317 kPa — estimates. Placard wins.
PSI is the garage-hose number. For 235/65R16C a typical C-type van planning figure is 46 psi cold — about 3.17 bar or 317 kPa. TPMS typically warns near 35 psi (about 25% below a 46 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.
Estimated 235/65R16C pressure by load
Plus-sizing to 235/65R16C 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 | 46 psi / 3.17 bar / 317 kPa | 50 psi / 3.45 bar / 345 kPa |
| Typical occupancy | 46 psi / 3.17 bar / 317 kPa | 51 psi / 3.52 bar / 352 kPa |
| Payload / towing (sketch) | 47 psi / 3.24 bar / 324 kPa | 56 psi / 3.86 bar / 386 kPa |
PSI, bar and kPa
1 bar ≈ 14.5 psi; 1 psi ≈ 6.89 kPa. Planning midpoint for 235/65R16C: 46 psi = 3.17 bar = 317 kPa.

What 235/65R16C means
235/65R16C means a 235 millimetre section width, a sidewall that is 65 percent of that width, on a 16-inch rim. The R is radial construction.
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.

How to set 235/65R16C
- Measure before the school run, not after the motorway.
- Write LF / RF / RR / RL. Do not keep 235/65R16C numbers in your head.
- Add air in short bursts toward the placard, using 46 psi only as a map.
- If one 235/65R16C 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 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 |

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.
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.
What is 235/65R16C in bar?
46 psi is 3.17 bar. Add a tenth of a bar if the placard’s laden column is higher, which is common on vans that wear this size.
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.
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.
