215/45R16
35 psi / 2.41 bar
241 kPa · estimates for this size class
215/45R16 · 35 psi · 2.41 bar · 241 kPa — estimates. Placard wins.
Searches for “215/45R16 pressure” usually want a number. Use 35 psi (2.41 bar) only as a sketch; the door-pillar placard on the car that wears this size still wins. Under-inflation cooks the shoulders of a 215/45R16; over-inflation wears the centre rib and bangs every cat’s eye. 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.
What 215/45R16 means
Read 215/45R16 as width / aspect R rim. Nothing in the size string is a pressure. Pressure lives on the car, not moulded as 205 or 55.
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.
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 | 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 |
PSI, bar and kPa
1 bar ≈ 14.5 psi; 1 psi ≈ 6.89 kPa. Planning midpoint for 215/45R16: 35 psi = 2.41 bar = 241 kPa.

Placard versus sidewall
If a forum says “all 215/45R16 run 35 psi”, ignore it. A Qashqai and a Golf can share a size and not share a sticker.

These catalogue models are often seen on 215/45R16 or a close OEM neighbour. Open the vehicle chart for axle-specific PSI and bar.
How to set 215/45R16
- Park so the 215/45R16 tyres are cold (three hours, or less than about a mile).
- Read the door-pillar placard for that car — not the 215/45R16 sidewall maximum.
- If the sticker is missing, 35 psi / 2.41 bar is only a passenger car planning figure for this size.
- Set all four with a calibrated gauge. A 3 psi miss on one corner shows up as a wander.
- Refit valve caps and reset TPMS if the handbook asks for a relearn.
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 |
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 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.
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.
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 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.
