2.41 bar · 35 psi · 100 kPa = 1 bar
255/70R16 · 35 psi · 2.41 bar · 241 kPa — estimates. Placard wins.
If the gauge only speaks kPa, 241 kPa is the sketch for this pickup / double-cab size. Fine-tune to the vehicle that actually wears 255/70R16. Under-inflation cooks the shoulders of a 255/70R16; over-inflation wears the centre rib and bangs every cat’s eye.
kPa, bar and PSI
Convert around the 255/70R16 band. 2.41 bar is about 35 psi — not 23, not 33 unless the maths says so.

| 214 | 2.14 | 31 |
| 221 | 2.21 | 32 |

Estimated 255/70R16 pressure by load
Load moves the rear first on a pickup / double-cab. If the factory placard already has a laden column, use that — not this sketch for 255/70R16.
| Condition | Front (est.) | Rear (est.) |
|---|---|---|
| Driver only / unladen | 35 psi / 2.41 bar / 241 kPa | 39 psi / 2.69 bar / 269 kPa |
| Typical occupancy | 35 psi / 2.41 bar / 241 kPa | 40 psi / 2.76 bar / 276 kPa |
| Payload / towing (sketch) | 36 psi / 2.48 bar / 248 kPa | 41 psi / 2.83 bar / 283 kPa |
What 255/70R16 means
255/70R16 means a 255 millimetre section width, a sidewall that is 70 percent of that width, on a 16-inch rim. The R is radial construction.
16-inch crossover-truck overlap. Rim diameter 16 in; section 255 mm. Estimates on this page assume a typical load index for the pickup / double-cab class.
Placard versus sidewall
The sidewall of a 255/70R16 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.
Temperature drift
Roughly 1 psi per 5–6 °C. The table uses 35 psi as a 20 °C baseline for 255/70R16.
| Ambient | Gauge | Bar | kPa | Note |
|---|---|---|---|---|
| −5 °C (hard frost) | 32 psi | 2.21 bar | 221 kPa | Gauge reads low; do not overfill once warm |
| 0 °C | 33 psi | 2.28 bar | 228 kPa | Gauge reads low; do not overfill once warm |
| 8 °C (UK winter morning) | 34 psi | 2.34 bar | 234 kPa | Gauge reads low; do not overfill once warm |
| 20 °C (set cold here) | 35 psi | 2.41 bar | 241 kPa | Baseline for this size sketch |
| 30 °C | 37 psi | 2.55 bar | 255 kPa | Do not bleed a hot 255/70R16 |
| 38 °C (heatwave tarmac) | 38 psi | 2.62 bar | 262 kPa | Do not bleed a hot 255/70R16 |
How to set 255/70R16
- Measure before the school run, not after the motorway.
- Write LF / RF / RR / RL. Do not keep 255/70R16 numbers in your head.
- Add air in short bursts toward the placard, using 35 psi only as a map.
- If one 255/70R16 is 4 psi down, hunt for a nail before you blame the weather.
- Log date, ambient temperature and the four readings.

Questions about 255/70R16
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 255/70R16 at a lower pressure for comfort?
Not as a habit. A soft 255/70R16 cooks the shoulders and dulls steering. Keep load index and stay on the placard.
Is the sidewall number correct for 255/70R16?
No. Sidewall PSI or kPa is a maximum for the carcass. Operating pressure is the door-pillar placard.
What PSI should 255/70R16 tyres be?
A pickup / double-cab planning figure is about 35 psi cold (2.41 bar / 241 kPa). Confirm on the vehicle placard — two cars can share 255/70R16 and not share a sticker.
What is 255/70R16 in bar?
35 psi is 2.41 bar. Add a tenth of a bar if the placard’s laden column is higher, which is common on vans that wear this size.
