2.34 bar · 234 kPa · passenger car planning figure
205/45R16 · 34 psi · 2.34 bar · 234 kPa — estimates. Placard wins.
If someone typed “205/45R16 psi”, they want Imperial. Start near 34 psi on an unladen passenger car, then confirm the vehicle placard. Sidewall max is not the target. A 10 °C overnight drop takes roughly 1 psi (0.07 bar) off a closed 205/45R16. 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.
Estimated 205/45R16 pressure by load
Plus-sizing to 205/45R16 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 | 34 psi / 2.34 bar / 234 kPa | 34 psi / 2.34 bar / 234 kPa |
| Typical occupancy | 34 psi / 2.34 bar / 234 kPa | 35 psi / 2.41 bar / 241 kPa |
| Motorway + luggage (sketch) | 35 psi / 2.41 bar / 241 kPa | 36 psi / 2.48 bar / 248 kPa |
PSI, bar and kPa
Use the table, then set a cold gauge. 234 kPa is 100 × 2.34 bar on this size.

What 205/45R16 means
205/45R16 means a 205 millimetre section width, a sidewall that is 45 percent of that width, on a 16-inch rim. The R is radial construction.
Low-profile 16-inch. Rim diameter 16 in; section 205 mm. Estimates on this page assume a typical load index for the passenger car class.
Placard versus sidewall
This website maps size searches such as “205/45R16 psi”. It does not replace the VIN label. If the two disagree, the label wins.

How to set 205/45R16
- Measure before the school run, not after the motorway.
- Write LF / RF / RR / RL. Do not keep 205/45R16 numbers in your head.
- Add air in short bursts toward the placard, using 34 psi only as a map.
- If one 205/45R16 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 34 psi as a 20 °C baseline for 205/45R16.
| Ambient | Gauge | Bar | kPa | Note |
|---|---|---|---|---|
| −5 °C (hard frost) | 31 psi | 2.14 bar | 214 kPa | Gauge reads low; do not overfill once warm |
| 0 °C | 32 psi | 2.21 bar | 221 kPa | Gauge reads low; do not overfill once warm |
| 8 °C (UK winter morning) | 33 psi | 2.28 bar | 228 kPa | Gauge reads low; do not overfill once warm |
| 20 °C (set cold here) | 34 psi | 2.34 bar | 234 kPa | Baseline for this size sketch |
| 30 °C | 36 psi | 2.48 bar | 248 kPa | Do not bleed a hot 205/45R16 |
| 38 °C (heatwave tarmac) | 37 psi | 2.55 bar | 255 kPa | Do not bleed a hot 205/45R16 |
If the door sticker and this 205/45R16 page disagree, the sticker wins.
Questions about 205/45R16
Is 205/45R16 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 205/45R16?
Direct TPMS typically flags about 25% below target — near 26 psi if you were aiming at 34. 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 PSI should 205/45R16 tyres be?
A passenger car planning figure is about 34 psi cold (2.34 bar / 234 kPa). Confirm on the vehicle placard — two cars can share 205/45R16 and not share a sticker.
Is the sidewall number correct for 205/45R16?
No. Sidewall PSI or kPa is a maximum for the carcass. Operating pressure is the door-pillar placard.
