The front axle of a BMW 323 steers and, on rear-wheel drive cars, often pulls as well. Catalogue front pressure is 32-35 psi / 2.2-2.4 bar. Size estimates on this page include 185/65R15, 205/55R16 and 225/50R17 — interpolated from the catalogue midpoint, not a second factory sticker.
BMW 323 placard versus sidewall
The tyre-information placard on a BMW 323 sits on the driver’s door pillar (sometimes the fuel-filler flap). Catalogue figures here are a general band: 32-35 / 32-35 psi.
Estimated pressure by tyre size (185/65R15 and others)
Planning cold pressures for sizes often seen on a passenger car. This 323 sample opens with 185/65R15, then 205/55R16 and 225/50R17.
| Tyre size | Front PSI | Rear PSI | Front bar | Rear bar | Front kPa | Rear kPa | Note |
|---|---|---|---|---|---|---|---|
| 185/65R15 | 33 | — | 2.28 | — | 228 | — | Small / older car |
| 205/55R16 | 34 | — | 2.34 | — | 234 | — | Typical mid-compact OEM |
| 225/50R17 | 35 | — | 2.41 | — | 241 | — | Touring 17-inch |
| 195/65R15 | 34 | — | 2.34 | — | 234 | — | Very common compact |
| 215/50R17 | 35 | — | 2.41 | — | 241 | — | Plus-size 17-inch |

Pressure against load
Load moves the rear of a passenger car first. If the factory placard already has a “laden” column, use that instead of these sketches.
| Condition | Front (est.) | Rear (est.) |
|---|---|---|
| Driver only | 34 psi / 2.34 bar | 34 psi / 2.34 bar |
| Full occupancy | 34 psi / 2.34 bar | 35 psi / 2.41 bar |
| Motorway + luggage | 35 psi / 2.41 bar | 37 psi / 2.55 bar |
Steering feel on the 323 lives on this axle. Do not drop front pressure to “soften” a plus-size 225/50R17; you will roll the sidewall in a roundabout.
How to set the 323
- Park the BMW 323 for at least three hours (cold tyres).
- Use a calibrated gauge, not the only meter on a forecourt hose.
- Set the placard for that axle — about 32-35 psi / 2.2-2.4 bar front and 32-35 psi / 2.2-2.4 bar rear on this catalogue row.
- Recheck all four. A 2 psi miss on a rear-wheel drive 323 is enough to feel a pull.
- 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 34 psi as a 20 °C baseline for this 323.
| Ambient | Gauge (front mid) | 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 |
| 30 °C | 36 psi | 2.48 bar | 248 kPa | Do not bleed a hot tyre |
| 38 °C (heatwave tarmac) | 37 psi | 2.55 bar | 255 kPa | Do not bleed a hot tyre |
BMW notes
BMW run-flats still want the placard. Comfort settings in the iDrive do not replace the door-pillar figure on this 323.
Spare and inflator kit
A matching full-size spare on the BMW 323 usually follows the higher axle (often the rear, near 32-35 psi). A space-saver is commonly 60 psi / 4.1 bar — read that tyre’s own sidewall. An inflator kit is not a spare; check the sealant date.
If the BMW sticker and this page disagree, the sticker wins.

Questions about this 323
What is that in bar and kPa for the 323?
Mid-points are about 2.31 bar (231 kPa) front and 2.31 bar (231 kPa) rear.
How often should I check a 323?
Monthly, before a long trip, and after a 10 °C weather swing. Include a full-size spare.
Front versus rear on the BMW 323?
This row is 32-35 F / 32-35 R. Even when they match, a laden rear can justify a higher number if the sticker prints one.
When does TPMS warn on a BMW 323?
Direct TPMS typically flags about 25% below placard — near 25 psi on this row. Fill to the sticker, not to the lamp.
What tyre pressure should a BMW 323 use?
Catalogue reference is 32-35 psi front and 32-35 psi rear (2.2-2.4 / 2.2-2.4 bar), cold. Confirm on the door-pillar placard.
