50 psi · 345 kPa · not a second factory sticker
LT225/75R16 · 50 psi · 3.45 bar · 345 kPa — estimates. Placard wins.
European stickers print bar. LT225/75R16 often sits near 3.45 bar on a LT-metric truck (50 psi / 345 kPa). 3.45 bar is not “50 divided by ten”. LT 16-inch light truck. 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.
Bar, PSI and kPa

Estimated LT225/75R16 pressure by load
These LT225/75R16 load steps are ± a few PSI from 50. They are not a licence to ignore a printed second column on a van or estate.
| Condition | Front (est.) | Rear (est.) |
|---|---|---|
| Driver only / unladen | 50 psi / 3.45 bar / 345 kPa | 52 psi / 3.59 bar / 359 kPa |
| Typical occupancy | 51 psi / 3.52 bar / 352 kPa | 54 psi / 3.72 bar / 372 kPa |
| Payload / towing (sketch) | 52 psi / 3.59 bar / 359 kPa | 61 psi / 4.21 bar / 421 kPa |
Placard versus sidewall
This website maps size searches such as “LT225/75R16 psi”. It does not replace the VIN label. If the two disagree, the label wins.
What LT225/75R16 means
Read LT225/75R16 as width / aspect R rim. Nothing in the size string is a pressure. Pressure lives on the car, not moulded as 205 or 55.
LT 16-inch light truck. Rim diameter 16 in; section 225 mm. Estimates on this page assume a typical load index for the LT-metric truck class.

How to set LT225/75R16
- Measure before the school run, not after the motorway.
- Write LF / RF / RR / RL. Do not keep LT225/75R16 numbers in your head.
- Add air in short bursts toward the placard, using 50 psi only as a map.
- If one LT225/75R16 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 50 psi as a 20 °C baseline for LT225/75R16.
| Ambient | Gauge | Bar | kPa | Note |
|---|---|---|---|---|
| −5 °C (hard frost) | 47 psi | 3.24 bar | 324 kPa | Gauge reads low; do not overfill once warm |
| 0 °C | 48 psi | 3.31 bar | 331 kPa | Gauge reads low; do not overfill once warm |
| 8 °C (UK winter morning) | 49 psi | 3.38 bar | 338 kPa | Gauge reads low; do not overfill once warm |
| 20 °C (set cold here) | 50 psi | 3.45 bar | 345 kPa | Baseline for this size sketch |
| 30 °C | 52 psi | 3.59 bar | 359 kPa | Do not bleed a hot LT225/75R16 |
| 38 °C (heatwave tarmac) | 53 psi | 3.65 bar | 365 kPa | Do not bleed a hot LT225/75R16 |
If the door sticker and this LT225/75R16 page disagree, the sticker wins.
Questions about LT225/75R16
Is LT225/75R16 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 LT225/75R16?
Direct TPMS typically flags about 25% below target — near 38 psi if you were aiming at 50. Fill to the sticker, not to the lamp.
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.
Is the sidewall number correct for LT225/75R16?
No. Sidewall PSI or kPa is a maximum for the carcass. Operating pressure is the door-pillar placard.
What is LT225/75R16 in kPa?
345 kPa is the planning midpoint (100 kPa = 1 bar). 352 kPa is one PSI higher.
