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.

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.

ConditionFront (est.)Rear (est.)
Driver only34 psi / 2.34 bar34 psi / 2.34 bar
Full occupancy34 psi / 2.34 bar35 psi / 2.41 bar
Motorway + luggage35 psi / 2.41 bar38 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

  1. Measure before the school run, not after the M25.
  2. Write LF / RF / RR / RL. Do not keep Giulietta numbers in your head.
  3. Add air in short bursts toward 34 psi (2.31 bar) front and 34 psi rear.
  4. If one corner is 4 psi down, hunt for a nail before you blame the weather.
  5. Log date, ambient temperature and the four readings.

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.
