PSI is the Imperial reading most UK motorists still see on garage hoses. For the Chevrolet Monza Sport Sedan the catalogue row is 32-35 psi front and 32-35 psi rear. A 10 °C overnight drop takes roughly 1 psi (0.07 bar) off a closed Chevrolet tyre.

Chevrolet Monza Sport Sedan placard versus sidewall

The tyre-information placard on a Chevrolet Monza Sport Sedan 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 (225/40R18 and others)

If your Chevrolet Monza Sport Sedan no longer wears the OEM diameter, start at the row nearest 225/40R18 or 225/45R17 and confirm with the tyre maker’s load table.

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

How to set the Monza Sport Sedan

Measure before the school run, not after the M25.
Write LF / RF / RR / RL. Do not keep Monza Sport Sedan 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.

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	35 psi / 2.41 bar	36 psi / 2.48 bar
Motorway + luggage	36 psi / 2.48 bar	36 psi / 2.48 bar

Temperature drift

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

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

Chevrolet notes

No special Chevrolet exception: the Monza Sport Sedan 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 Chevrolet Monza Sport Sedan 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 Monza Sport Sedan than nitrogen upsells.
