35 psi · 241 kPa · not a second factory sticker
255/70R16 · 35 psi · 2.41 bar · 241 kPa — estimates. Placard wins.
European stickers print bar. 255/70R16 often sits near 2.41 bar on a pickup / double-cab (35 psi / 241 kPa). 2.41 bar is not “35 divided by ten”. TPMS typically warns near 26 psi (about 25% below a 35 psi target). That is already a soft tyre.
Bar, PSI and kPa
1 bar ≈ 14.5 psi; 1 psi ≈ 6.89 kPa. Planning midpoint for 255/70R16: 35 psi = 2.41 bar = 241 kPa.

Estimated 255/70R16 pressure by load
Plus-sizing to 255/70R16 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 | 35 psi / 2.41 bar / 241 kPa | 37 psi / 2.55 bar / 255 kPa |
| Typical occupancy | 36 psi / 2.48 bar / 248 kPa | 39 psi / 2.69 bar / 269 kPa |
| Payload / towing (sketch) | 37 psi / 2.55 bar / 255 kPa | 40 psi / 2.76 bar / 276 kPa |
Placard versus sidewall
If a forum says “all 255/70R16 run 35 psi”, ignore it. A Qashqai and a Golf can share a size and not share a sticker.
What 255/70R16 means
A 255/70R16 on a pickup / double-cab is a geometry. Two cars can share the size and disagree on PSI because mass and axle split differ.
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.

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.
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 |
Keep 255/70R16 on the printed band for that car; 35 psi is a size sketch, not a second VIN label.
Questions about 255/70R16
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.
Is 255/70R16 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 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.
What is 255/70R16 in kPa?
241 kPa is the planning midpoint (100 kPa = 1 bar). 248 kPa is one PSI higher.
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.
