3.79 bar · 55 psi · 100 kPa = 1 bar
LT245/75R16 · 55 psi · 3.79 bar · 379 kPa — estimates. Placard wins.
Kilopascals show up on some Asian stickers and ISO sheets. 379 kPa is the planning midpoint for LT245/75R16 (3.79 bar / 55 psi). 100 kPa = 1 bar. Common LT half-ton 16-inch. These rows are estimates interpolated for the size, not OEM for a named VIN. LT-metric sizes print a load range. The vehicle door sticker, not the LT sidewall maximum, is still the operating pressure.
kPa, bar and PSI
1 bar ≈ 14.5 psi; 1 psi ≈ 6.89 kPa. Planning midpoint for LT245/75R16: 55 psi = 3.79 bar = 379 kPa.

Estimated LT245/75R16 pressure by load
Load moves the rear first on a LT-metric truck. If the factory placard already has a laden column, use that — not this sketch for LT245/75R16.
| Condition | Front (est.) | Rear (est.) |
|---|---|---|
| Driver only / unladen | 55 psi / 3.79 bar / 379 kPa | 57 psi / 3.93 bar / 393 kPa |
| Typical occupancy | 55 psi / 3.79 bar / 379 kPa | 58 psi / 4 bar / 400 kPa |
| Payload / towing (sketch) | 56 psi / 3.86 bar / 386 kPa | 65 psi / 4.48 bar / 448 kPa |
What LT245/75R16 means
A LT245/75R16 on a LT-metric truck is a geometry. Two cars can share the size and disagree on PSI because mass and axle split differ.
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.
Placard versus sidewall
The sidewall of a LT245/75R16 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 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 |
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.
Cars often seen on LT245/75R16
These catalogue models are often seen on LT245/75R16 or a close OEM neighbour. Open the vehicle chart for axle-specific PSI and bar.
A cheap gauge and a monthly habit will do more for a set of LT245/75R16 than nitrogen upsells.
Questions about LT245/75R16
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.
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.
What PSI should LT245/75R16 tyres be?
A LT-metric truck planning figure is about 55 psi cold (3.79 bar / 379 kPa). Confirm on the vehicle placard — two cars can share LT245/75R16 and not share a sticker.
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 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.
