UK winter mornings will show a lower gauge on this Brera without a puncture. Set 34/34 psi at ~20 °C equivalent, not after a motorway blast. A 10 °C overnight drop takes roughly 1 psi (0.07 bar) off a closed Alfa Romeo tyre.

Temperature and a cold gauge

Roughly 1 psi per 5–6 °C. The table uses 34 psi as a 20 °C baseline for this Brera.

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

How to set the Brera

Park the Alfa Romeo Brera 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 front-wheel drive Brera is enough to feel a pull.
Refit valve caps and reset TPMS if the handbook asks for a relearn.

Alfa Romeo Brera placard versus sidewall

Sidewall PSI is a carcass maximum. Recommended operating pressure for this Brera is the pillar sticker, near 34/34 psi.

Estimated pressure by tyre size (225/40R18 and others)

225/40R18 is the first planning size here. 185/65R15 is usually the plus-size or LT step. Keep load index at or above original equipment.

Tyre size	Front PSI	Rear PSI	Front bar	Rear bar	Front kPa	Rear kPa	Note
225/40R18	36	36	2.48	2.48	248	248	Low-profile 18-inch
215/50R17	35	35	2.41	2.41	241	241	Plus-size 17-inch
185/65R15	33	33	2.28	2.28	228	228	Small / older car
205/55R16	34	34	2.34	2.34	234	234	Typical mid-compact OEM
205/60R16	34	34	2.34	2.34	234	234	Taller 16-inch
195/65R15	34	34	2.34	2.34	234	234	Very common compact

Load notes

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

Alfa Romeo notes

No special Alfa Romeo exception: the Brera 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 Brera 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 Alfa Romeo sticker and this page disagree, the sticker wins.

Questions about this Brera

Front versus rear on the Alfa Romeo Brera?

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.

Is the sidewall number correct on a Alfa Romeo Brera?

No. Sidewall PSI is a maximum. The Brera placard is the operating target, near 32-35/32-35 psi.

What tyre pressure should a Alfa Romeo Brera 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.

How often should I check a Brera?

Monthly, before a long trip, and after a 10 °C weather swing. Include a full-size spare.

What PSI if I plus-size toward 185/65R15?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 225/40R18, 215/50R17 and 185/65R15 as a planning band.
