55 psi · 379 kPa · not a second factory sticker
LT245/75R16 · 55 psi · 3.79 bar · 379 kPa — estimates. Placard wins.
A LT245/75R16 C-type or LT carcass can live far above a hatchback bar figure. This page’s 3.79 bar sketch is for the LT-metric truck class, not every car that can physically mount the tyre. A 10 °C overnight drop takes roughly 1 psi (0.07 bar) off a closed LT245/75R16. LT-metric sizes print a load range. The vehicle door sticker, not the LT sidewall maximum, is still the operating pressure.
Bar, PSI and kPa
Use the table, then set a cold gauge. 379 kPa is 100 × 3.79 bar on this size.
| Bar | PSI | kPa |
|---|---|---|
| 3.03 | 44 | 303 |
| 3.17 | 46 | 317 |
| 3.45 | 50 | 345 |
| 3.52 | 51 | 352 |

Estimated LT245/75R16 pressure by load
These LT245/75R16 load steps are ± a few PSI from 55. They are not a licence to ignore a printed second column on a van or estate.
| Condition | Front (est.) | Rear (est.) |
|---|---|---|
| Driver only / unladen | 55 psi / 3.79 bar / 379 kPa | 59 psi / 4.07 bar / 407 kPa |
| Typical occupancy | 56 psi / 3.86 bar / 386 kPa | 61 psi / 4.21 bar / 421 kPa |
| Payload / towing (sketch) | 57 psi / 3.93 bar / 393 kPa | 68 psi / 4.69 bar / 469 kPa |
Placard versus sidewall
If a forum says “all LT245/75R16 run 55 psi”, ignore it. A Qashqai and a Golf can share a size and not share a sticker.
What LT245/75R16 means
Read LT245/75R16 as width / aspect R rim. Nothing in the size string is a pressure. Pressure lives on the car, not moulded as 205 or 55.
Common LT half-ton 16-inch. Rim diameter 16 in; section 245 mm. Estimates on this page assume a typical load index for the LT-metric truck class.

How to set LT245/75R16
- Measure before the school run, not after the motorway.
- Write LF / RF / RR / RL. Do not keep LT245/75R16 numbers in your head.
- Add air in short bursts toward the placard, using 55 psi only as a map.
- If one LT245/75R16 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 55 psi as a 20 °C baseline for LT245/75R16.
| Ambient | Gauge | Bar | kPa | Note |
|---|---|---|---|---|
| −5 °C (hard frost) | 52 psi | 3.59 bar | 359 kPa | Gauge reads low; do not overfill once warm |
| 0 °C | 53 psi | 3.65 bar | 365 kPa | Gauge reads low; do not overfill once warm |
| 8 °C (UK winter morning) | 54 psi | 3.72 bar | 372 kPa | Gauge reads low; do not overfill once warm |
| 20 °C (set cold here) | 55 psi | 3.79 bar | 379 kPa | Baseline for this size sketch |
| 30 °C | 57 psi | 3.93 bar | 393 kPa | Do not bleed a hot LT245/75R16 |
| 38 °C (heatwave tarmac) | 58 psi | 4 bar | 400 kPa | Do not bleed a hot LT245/75R16 |
A cheap gauge and a monthly habit will do more for a set of LT245/75R16 than nitrogen upsells.
Questions about LT245/75R16
Is the sidewall number correct for LT245/75R16?
No. Sidewall PSI or kPa is a maximum for the carcass. Operating pressure is the door-pillar placard.
What is LT245/75R16 in bar?
55 psi is 3.79 bar. Add a tenth of a bar if the placard’s laden column is higher, which is common on vans that wear this size.
Is LT245/75R16 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.
When does TPMS warn on LT245/75R16?
Direct TPMS typically flags about 25% below target — near 41 psi if you were aiming at 55. Fill to the sticker, not to the lamp.
Can I run LT245/75R16 at a lower pressure for comfort?
Not as a habit. A soft LT245/75R16 cooks the shoulders and dulls steering. Keep load index and stay on the placard.
