35 psi / 2.41 bar
241 kPa · estimates for this size class
235/60R17 · 35 psi · 2.41 bar · 241 kPa — estimates. Placard wins.
235/60R17 is a SUV / crossover size (235 mm section, 60 % aspect, 17-inch rim). A planning cold figure around 35 psi / 2.41 bar / 241 kPa is a starting map, not a second factory sticker. Taller mid-SUV 17-inch. These rows are estimates interpolated for the size, not OEM for a named VIN.
What 235/60R17 means
A 235/60R17 on a SUV / crossover is a geometry. Two cars can share the size and disagree on PSI because mass and axle split differ.
Taller mid-SUV 17-inch. Rim diameter 17 in; section 235 mm. Estimates on this page assume a typical load index for the SUV / crossover class.
Estimated 235/60R17 pressure by load
These 235/60R17 load steps are ± a few PSI from 35. They are not a licence to ignore a printed second column on a van or estate.
| Condition | Front (est.) | Rear (est.) |
|---|---|---|
| Driver only / unladen | 35 psi / 2.41 bar / 241 kPa | 36 psi / 2.48 bar / 248 kPa |
| Typical occupancy | 35 psi / 2.41 bar / 241 kPa | 37 psi / 2.55 bar / 255 kPa |
| Motorway + luggage (sketch) | 36 psi / 2.48 bar / 248 kPa | 38 psi / 2.62 bar / 262 kPa |
PSI, bar and kPa
Convert around the 235/60R17 band. 2.41 bar is about 35 psi — not 23, not 33 unless the maths says so.

Placard versus sidewall
The sidewall of a 235/60R17 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 235/60R17
- Measure before the school run, not after the motorway.
- Write LF / RF / RR / RL. Do not keep 235/60R17 numbers in your head.
- Add air in short bursts toward the placard, using 35 psi only as a map.
- If one 235/60R17 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 35 psi as a 20 °C baseline for 235/60R17.
| Ambient | Gauge | Bar | kPa | Note |
|---|---|---|---|---|
| −5 °C (hard frost) | 32 psi | 2.21 bar | 221 kPa | Gauge reads low; do not overfill once warm |
| 0 °C | 33 psi | 2.28 bar | 228 kPa | Gauge reads low; do not overfill once warm |
| 8 °C (UK winter morning) | 34 psi | 2.34 bar | 234 kPa | Gauge reads low; do not overfill once warm |
| 20 °C (set cold here) | 35 psi | 2.41 bar | 241 kPa | Baseline for this size sketch |
| 30 °C | 37 psi | 2.55 bar | 255 kPa | Do not bleed a hot 235/60R17 |
| 38 °C (heatwave tarmac) | 38 psi | 2.62 bar | 262 kPa | Do not bleed a hot 235/60R17 |
A cheap gauge and a monthly habit will do more for a set of 235/60R17 than nitrogen upsells.
Questions about 235/60R17
Can I run 235/60R17 at a lower pressure for comfort?
Not as a habit. A soft 235/60R17 cooks the shoulders and dulls steering. Keep load index and stay on the placard.
When does TPMS warn on 235/60R17?
Direct TPMS typically flags about 25% below target — near 26 psi if you were aiming at 35. 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.
What is 235/60R17 in bar?
35 psi is 2.41 bar. Add a tenth of a bar if the placard’s laden column is higher, which is common on vans that wear this size.
What is 235/60R17 in kPa?
241 kPa is the planning midpoint (100 kPa = 1 bar). 248 kPa is one PSI higher.
