35 psi · 241 kPa · not a second factory sticker
215/45R16 · 35 psi · 2.41 bar · 241 kPa — estimates. Placard wins.
European stickers print bar. 215/45R16 often sits near 2.41 bar on a passenger car (35 psi / 241 kPa). 2.41 bar is not “35 divided by ten”. Wide low 16-inch. These rows are estimates interpolated for the size, not OEM for a named VIN. Low-profile {sz} does not want a “softer” pressure to recover ride. Stay at or slightly above the car’s original placard if load index is kept.
Bar, PSI and kPa
Use the table, then set a cold gauge. 241 kPa is 100 × 2.41 bar on this size.
| Bar | PSI | kPa |
|---|---|---|
| 2.14 | 31 | 214 |
| 2.21 | 32 | 221 |
| 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 |

Estimated 215/45R16 pressure by load
Plus-sizing to 215/45R16 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 | 35 psi / 2.41 bar / 241 kPa | 35 psi / 2.41 bar / 241 kPa |
| Typical occupancy | 35 psi / 2.41 bar / 241 kPa | 36 psi / 2.48 bar / 248 kPa |
| Motorway + luggage (sketch) | 36 psi / 2.48 bar / 248 kPa | 37 psi / 2.55 bar / 255 kPa |
Placard versus sidewall
The sidewall of a 215/45R16 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.
What 215/45R16 means
A 215/45R16 on a passenger car is a geometry. Two cars can share the size and disagree on PSI because mass and axle split differ.
Wide low 16-inch. Rim diameter 16 in; section 215 mm. Estimates on this page assume a typical load index for the passenger car class.

How to set 215/45R16
- Measure before the school run, not after the motorway.
- Write LF / RF / RR / RL. Do not keep 215/45R16 numbers in your head.
- Add air in short bursts toward the placard, using 35 psi only as a map.
- If one 215/45R16 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 215/45R16.
| 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 215/45R16 |
| 38 °C (heatwave tarmac) | 38 psi | 2.62 bar | 262 kPa | Do not bleed a hot 215/45R16 |
A cheap gauge and a monthly habit will do more for a set of 215/45R16 than nitrogen upsells.
Questions about 215/45R16
What is 215/45R16 in kPa?
241 kPa is the planning midpoint (100 kPa = 1 bar). 248 kPa is one PSI higher.
Is the sidewall number correct for 215/45R16?
No. Sidewall PSI or kPa is a maximum for the carcass. Operating pressure is the door-pillar placard.
What PSI should 215/45R16 tyres be?
A passenger car planning figure is about 35 psi cold (2.41 bar / 241 kPa). Confirm on the vehicle placard — two cars can share 215/45R16 and not share a sticker.
Is 215/45R16 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.
When does TPMS warn on 215/45R16?
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.
