2.41 bar · 35 psi · 100 kPa = 1 bar
215/45R16 · 35 psi · 2.41 bar · 241 kPa — estimates. Placard wins.
Kilopascals show up on some Asian stickers and ISO sheets. 241 kPa is the planning midpoint for 215/45R16 (2.41 bar / 35 psi). 100 kPa = 1 bar. 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.
kPa, bar and PSI
Use the table, then set a cold gauge. 241 kPa is 100 × 2.41 bar on this size.

|---|---|---|
| 214 | 2.14 | 31 |
| 221 | 2.21 | 32 |
| 228 | 2.28 | 33 |
| 234 | 2.34 | 34 |

Estimated 215/45R16 pressure by load
Load moves the rear first on a passenger car. If the factory placard already has a laden column, use that — not this sketch for 215/45R16.
| Condition | Front (est.) | Rear (est.) |
|---|---|---|
| Driver only / unladen | 35 psi / 2.41 bar / 241 kPa | 35 psi / 2.41 bar / 241 kPa |
| Typical occupancy | 36 psi / 2.48 bar / 248 kPa | 37 psi / 2.55 bar / 255 kPa |
| Motorway + luggage (sketch) | 37 psi / 2.55 bar / 255 kPa | 38 psi / 2.62 bar / 262 kPa |
What 215/45R16 means
215/45R16 means a 215 millimetre section width, a sidewall that is 45 percent of that width, on a 16-inch rim. The R is radial construction.
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.
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.
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 |
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.
Cars often seen on 215/45R16
These catalogue models are often seen on 215/45R16 or a close OEM neighbour. Open the vehicle chart for axle-specific PSI and bar.
Keep 215/45R16 on the printed band for that car; 35 psi is a size sketch, not a second VIN label.
Questions about 215/45R16
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.
Can I run 215/45R16 at a lower pressure for comfort?
Not as a habit. A soft 215/45R16 cooks the shoulders and dulls steering. Keep load index and stay on the placard.
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.
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.
What is 215/45R16 in kPa?
241 kPa is the planning midpoint (100 kPa = 1 bar). 248 kPa is one PSI higher.
