248 kPa · estimates for this size class
265/65R17 · 36 psi · 2.48 bar · 248 kPa — estimates. Placard wins.
265/65R17 is a pickup / double-cab size (265 mm section, 65 % aspect, 17-inch rim). A planning cold figure around 36 psi / 2.48 bar / 248 kPa is a starting map, not a second factory sticker. TPMS typically warns near 27 psi (about 25% below a 36 psi target). That is already a soft tyre.
What 265/65R17 means
265/65R17 means a 265 millimetre section width, a sidewall that is 65 percent of that width, on a 17-inch rim. The R is radial construction.
Common 17-inch pickup. Rim diameter 17 in; section 265 mm. Estimates on this page assume a typical load index for the pickup / double-cab class.
Estimated 265/65R17 pressure by load
Plus-sizing to 265/65R17 from a taller OEM tyre usually keeps the same placard if the load index is equal or higher.
| Condition | Front (est.) | Rear (est.) |
|---|---|---|
| Driver only / unladen | 36 psi / 2.48 bar / 248 kPa | 38 psi / 2.62 bar / 262 kPa |
| Typical occupancy | 37 psi / 2.55 bar / 255 kPa | 40 psi / 2.76 bar / 276 kPa |
| Payload / towing (sketch) | 38 psi / 2.62 bar / 262 kPa | 41 psi / 2.83 bar / 283 kPa |
PSI, bar and kPa
1 bar ≈ 14.5 psi; 1 psi ≈ 6.89 kPa. Planning midpoint for 265/65R17: 36 psi = 2.48 bar = 248 kPa.

Placard versus sidewall
The sidewall of a 265/65R17 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.

How to set 265/65R17
- Measure before the school run, not after the motorway.
- Write LF / RF / RR / RL. Do not keep 265/65R17 numbers in your head.
- Add air in short bursts toward the placard, using 36 psi only as a map.
- If one 265/65R17 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 265/65R17.
| 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 265/65R17 |
| 38 °C (heatwave tarmac) | 39 psi | 2.69 bar | 269 kPa | Do not bleed a hot 265/65R17 |
If the door sticker and this 265/65R17 page disagree, the sticker wins.
Questions about 265/65R17
What is 265/65R17 in kPa?
248 kPa is the planning midpoint (100 kPa = 1 bar). 255 kPa is one PSI higher.
What is 265/65R17 in bar?
36 psi is 2.48 bar. Add a tenth of a bar if the placard’s laden column is higher, which is common on vans that wear this size.
When does TPMS warn on 265/65R17?
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.
Can I run 265/65R17 at a lower pressure for comfort?
Not as a habit. A soft 265/65R17 cooks the shoulders and dulls steering. Keep load index and stay on the placard.
Is 265/65R17 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.
