LT245/75R16
55 psi / 3.79 bar
379 kPa · estimates for this size class
LT245/75R16 · 55 psi · 3.79 bar · 379 kPa — estimates. Placard wins.
Searches for “LT245/75R16 pressure” usually want a number. Use 55 psi (3.79 bar) only as a sketch; the door-pillar placard on the car that wears this size still wins. Under-inflation cooks the shoulders of a LT245/75R16; over-inflation wears the centre rib and bangs every cat’s eye. LT-metric sizes print a load range. The vehicle door sticker, not the LT sidewall maximum, is still the operating pressure.
What LT245/75R16 means
LT245/75R16 means a 245 millimetre section width, a sidewall that is 75 percent of that width, on a 16-inch rim. The R is radial construction.
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.
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 | 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 |
PSI, bar and kPa
Convert around the LT245/75R16 band. 3.79 bar is about 55 psi — not 23, not 33 unless the maths says so.

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.

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 |
If the door sticker and this LT245/75R16 page disagree, the sticker wins.
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.
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.
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.
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.
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.
