265/50R20 · 37 psi · 2.55 bar · 255 kPa — estimates. Placard wins.
A 265/50R20 C-type or LT carcass can live far above a hatchback bar figure. This page’s 2.55 bar sketch is for the SUV / crossover 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 265/50R20.
Bar, PSI and kPa
Use the table, then set a cold gauge. 255 kPa is 100 × 2.55 bar on this size.
| Bar | PSI | kPa |
|---|---|---|
| 2.28 | 33 | 228 |
| 2.34 | 34 | 234 |
| 2.41 | 35 | 241 |
| 2.48 | 36 | 248 |
| 2.55 | 37 | 255 |
| 2.62 | 38 | 262 |
| 2.69 | 39 | 269 |
| 2.76 | 40 | 276 |
| 2.83 | 41 | 283 |
| 2.90 | 42 | 290 |
| 2.96 | 43 | 296 |
| 3.03 | 44 | 303 |
| 3.10 | 45 | 310 |
| 3.17 | 46 | 317 |

Estimated 265/50R20 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 265/50R20.
| Condition | Front (est.) | Rear (est.) |
|---|---|---|
| Driver only / unladen | 37 psi / 2.55 bar / 255 kPa | 39 psi / 2.69 bar / 269 kPa |
| Typical occupancy | 38 psi / 2.62 bar / 262 kPa | 41 psi / 2.83 bar / 283 kPa |
| Motorway + luggage (sketch) | 39 psi / 2.69 bar / 269 kPa | 42 psi / 2.9 bar / 290 kPa |
Placard versus sidewall
This website maps size searches such as “265/50R20 psi”. It does not replace the VIN label. If the two disagree, the label wins.
What 265/50R20 means
265/50R20 means a 265 millimetre section width, a sidewall that is 50 percent of that width, on a 20-inch rim. The R is radial construction.
Wide 20-inch SUV. Rim diameter 20 in; section 265 mm. Estimates on this page assume a typical load index for the SUV / crossover class.

How to set 265/50R20
- Measure before the school run, not after the motorway.
- Write LF / RF / RR / RL. Do not keep 265/50R20 numbers in your head.
- Add air in short bursts toward the placard, using 37 psi only as a map.
- If one 265/50R20 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 37 psi as a 20 °C baseline for 265/50R20.
| Ambient | Gauge | Bar | kPa | Note |
|---|---|---|---|---|
| −5 °C (hard frost) | 34 psi | 2.34 bar | 234 kPa | Gauge reads low; do not overfill once warm |
| 0 °C | 35 psi | 2.41 bar | 241 kPa | Gauge reads low; do not overfill once warm |
| 8 °C (UK winter morning) | 36 psi | 2.48 bar | 248 kPa | Gauge reads low; do not overfill once warm |
| 20 °C (set cold here) | 37 psi | 2.55 bar | 255 kPa | Baseline for this size sketch |
| 30 °C | 39 psi | 2.69 bar | 269 kPa | Do not bleed a hot 265/50R20 |
| 38 °C (heatwave tarmac) | 40 psi | 2.76 bar | 276 kPa | Do not bleed a hot 265/50R20 |
Keep 265/50R20 on the printed band for that car; 37 psi is a size sketch, not a second VIN label.
Questions about 265/50R20
What is 265/50R20 in bar?
37 psi is 2.55 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 265/50R20 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 is 265/50R20 in kPa?
255 kPa is the planning midpoint (100 kPa = 1 bar). 262 kPa is one PSI higher.
Can I run 265/50R20 at a lower pressure for comfort?
Not as a habit. A soft 265/50R20 cooks the shoulders and dulls steering. Keep load index and stay on the placard.
What PSI should 265/50R20 tyres be?
A SUV / crossover planning figure is about 37 psi cold (2.55 bar / 255 kPa). Confirm on the vehicle placard — two cars can share 265/50R20 and not share a sticker.
