2.31 bar · 231 kPa at the rear axle
32-35 psi F · 32-35 psi R · 2.2-2.4 / 2.2-2.4 bar · 231/231 kPa
The rear of a passenger car takes passengers, luggage and, on vans, payload. Catalogue rear pressure on the Alfa Romeo Giulietta is 32-35 psi / 2.2-2.4 bar. TPMS typically warns near 25 psi (about 25% below target). That is already a soft tyre, not a fill target.

Estimated pressure by tyre size (185/65R15 and others)
Planning cold pressures for sizes often seen on a passenger car. This Giulietta sample opens with 185/65R15, then 205/60R16 and 215/55R16.
| Tyre size | Front PSI | Rear PSI | Front bar | Rear bar | Front kPa | Rear kPa | Note |
|---|---|---|---|---|---|---|---|
| 185/65R15 | — | 33 | — | 2.28 | — | 228 | Small / older car |
| 205/60R16 | — | 34 | — | 2.34 | — | 234 | Taller 16-inch |
| 215/55R16 | — | 35 | — | 2.41 | — | 241 | Slightly wider 16-inch |
| 225/45R17 | — | 35 | — | 2.41 | — | 241 | Sport 17-inch |
| 205/55R16 | — | 34 | — | 2.34 | — | 234 | Typical mid-compact OEM |
| 225/50R17 | — | 35 | — | 2.41 | — | 241 | Touring 17-inch |
| 245/40R18 | — | 36 | — | 2.48 | — | 248 | Wide touring 18-inch |
| 195/65R15 | — | 34 | — | 2.34 | — | 234 | Very common compact |
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 | 38 psi / 2.62 bar |
A family passenger car with a boot full of luggage should use the laden rear figure if Ford, VW or Mercedes printed one. Otherwise the modest steps in the load table are only a sketch for this Giulietta.
How to set the Giulietta
- Measure before the school run, not after the M25.
- Write LF / RF / RR / RL. Do not keep Giulietta numbers in your head.
- Add air in short bursts toward 34 psi (2.31 bar) front and 34 psi rear.
- If one corner 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 this Giulietta.
| 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 |
Alfa Romeo notes
No special Alfa Romeo exception: the Giulietta uses the door-pillar placard. Size estimates on this page only help if you have left the original load index behind.
Spare and inflator kit
A matching full-size spare on the Alfa Romeo Giulietta 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.
A cheap gauge and a monthly habit will do more for this Giulietta than nitrogen upsells.

Questions about this Giulietta
Front versus rear on the Alfa Romeo Giulietta?
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.
How often should I check a Giulietta?
Monthly, before a long trip, and after a 10 °C weather swing. Include a full-size spare.
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 tyre pressure should a Alfa Romeo Giulietta 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.
Is the sidewall number correct on a Alfa Romeo Giulietta?
No. Sidewall PSI is a maximum. The Giulietta placard is the operating target, near 32-35/32-35 psi.
