2.48 bar · 248 kPa · SUV / crossover planning figure
245/55R19 · 36 psi · 2.48 bar · 248 kPa — estimates. Placard wins.
PSI is the garage-hose number. For 245/55R19 a typical SUV / crossover planning figure is 36 psi cold — about 2.48 bar or 248 kPa. TPMS typically warns near 27 psi (about 25% below a 36 psi target). That is already a soft tyre.
Estimated 245/55R19 pressure by load
Load moves the rear first on a SUV / crossover. If the factory placard already has a laden column, use that — not this sketch for 245/55R19.
| Condition | Front (est.) | Rear (est.) |
|---|---|---|
| Driver only / unladen | 36 psi / 2.48 bar / 248 kPa | 38 psi / 2.62 bar / 262 kPa |
| Typical occupancy | 36 psi / 2.48 bar / 248 kPa | 39 psi / 2.69 bar / 269 kPa |
| Motorway + luggage (sketch) | 37 psi / 2.55 bar / 255 kPa | 40 psi / 2.76 bar / 276 kPa |
PSI, bar and kPa
Convert around the 245/55R19 band. 2.48 bar is about 36 psi — not 23, not 33 unless the maths says so.
| PSI | Bar | kPa |

| 32 | 2.21 | 221 |
| 33 | 2.28 | 228 |
| 34 | 2.34 | 234 |
| 35 | 2.41 | 241 |

What 245/55R19 means
Read 245/55R19 as width / aspect R rim. Nothing in the size string is a pressure. Pressure lives on the car, not moulded as 205 or 55.
Low-profile 19-inch SUV. Rim diameter 19 in; section 245 mm. Estimates on this page assume a typical load index for the SUV / crossover class.
Placard versus sidewall
If a forum says “all 245/55R19 run 36 psi”, ignore it. A Qashqai and a Golf can share a size and not share a sticker.

How to set 245/55R19
- Measure before the school run, not after the motorway.
- Write LF / RF / RR / RL. Do not keep 245/55R19 numbers in your head.
- Add air in short bursts toward the placard, using 36 psi only as a map.
- If one 245/55R19 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 36 psi as a 20 °C baseline for 245/55R19.
| Ambient | Gauge | Bar | kPa | Note |
|---|---|---|---|---|
| −5 °C (hard frost) | 33 psi | 2.28 bar | 228 kPa | Gauge reads low; do not overfill once warm |
| 0 °C | 34 psi | 2.34 bar | 234 kPa | Gauge reads low; do not overfill once warm |
| 8 °C (UK winter morning) | 35 psi | 2.41 bar | 241 kPa | Gauge reads low; do not overfill once warm |
| 20 °C (set cold here) | 36 psi | 2.48 bar | 248 kPa | Baseline for this size sketch |
| 30 °C | 38 psi | 2.62 bar | 262 kPa | Do not bleed a hot 245/55R19 |
| 38 °C (heatwave tarmac) | 39 psi | 2.69 bar | 269 kPa | Do not bleed a hot 245/55R19 |
A cheap gauge and a monthly habit will do more for a set of 245/55R19 than nitrogen upsells.
Questions about 245/55R19
Is 245/55R19 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 245/55R19 tyres be?
A SUV / crossover planning figure is about 36 psi cold (2.48 bar / 248 kPa). Confirm on the vehicle placard — two cars can share 245/55R19 and not share a sticker.
When does TPMS warn on 245/55R19?
Direct TPMS typically flags about 25% below target — near 27 psi if you were aiming at 36. Fill to the sticker, not to the lamp.
Is the sidewall number correct for 245/55R19?
No. Sidewall PSI or kPa is a maximum for the carcass. Operating pressure is the door-pillar placard.
Can I run 245/55R19 at a lower pressure for comfort?
Not as a habit. A soft 245/55R19 cooks the shoulders and dulls steering. Keep load index and stay on the placard.
