35 psi / 2.41 bar
241 kPa · estimates for this size class
255/70R16 · 35 psi · 2.41 bar · 241 kPa — estimates. Placard wins.
Searches for “255/70R16 pressure” usually want a number. Use 35 psi (2.41 bar) only as a sketch; the door-pillar placard on the car that wears this size still wins. A 10 °C overnight drop takes roughly 1 psi (0.07 bar) off a closed 255/70R16.
What 255/70R16 means
Read 255/70R16 as width / aspect R rim. Nothing in the size string is a pressure. Pressure lives on the car, not moulded as 205 or 55.
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.
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 | 38 psi / 2.62 bar / 262 kPa |
| Typical occupancy | 36 psi / 2.48 bar / 248 kPa | 40 psi / 2.76 bar / 276 kPa |
| Payload / towing (sketch) | 37 psi / 2.55 bar / 255 kPa | 41 psi / 2.83 bar / 283 kPa |
PSI, bar and kPa

Placard versus sidewall
This website maps size searches such as “255/70R16 psi”. It does not replace the VIN label. If the two disagree, the label wins.

How to set 255/70R16
- Park so the 255/70R16 tyres are cold (three hours, or less than about a mile).
- Read the door-pillar placard for that car — not the 255/70R16 sidewall maximum.
- If the sticker is missing, 35 psi / 2.41 bar is only a pickup / double-cab 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 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 |
A cheap gauge and a monthly habit will do more for a set of 255/70R16 than nitrogen upsells.
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.
What is 255/70R16 in kPa?
241 kPa is the planning midpoint (100 kPa = 1 bar). 248 kPa is one PSI higher.
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 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.
