Opel Zafira Tourer front tyres: 32-35 psi / 2.2-2.4 bar

Drivetrain: front-wheel drive
Body: passenger car
PSI F / R: 32-35 / 32-35
Bar F / R: 2.2-2.4 / 2.2-2.4

psi front

2.31 bar · 231 kPa at the steering axle

32-35 psi F · 32-35 psi R · 2.2-2.4 / 2.2-2.4 bar · 231/231 kPa

A 3 psi miss on one front corner of this Zafira Tourer shows up as a wander before the TPMS lamp bothers you. Target 34 psi (2.31 bar) cold. Under-inflation cooks the shoulders of a Zafira Tourer; over-inflation wears the centre rib and bangs every cat’s eye.

Opel Zafira Tourer placard versus sidewall

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

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

Planning cold pressures for sizes often seen on a passenger car. This Zafira Tourer sample opens with 225/40R18, then 225/45R17 and 225/50R17.

Tyre size	Front PSI	Rear PSI	Front bar	Rear bar	Front kPa	Rear kPa	Note
225/40R18	36	—	2.48	—	248	—	Low-profile 18-inch
225/45R17	35	—	2.41	—	241	—	Sport 17-inch
225/50R17	35	—	2.41	—	241	—	Touring 17-inch
205/55R16	34	—	2.34	—	234	—	Typical mid-compact OEM
195/65R15	34	—	2.34	—	234	—	Very common compact
245/40R18	36	—	2.48	—	248	—	Wide touring 18-inch
205/60R16	34	—	2.34	—	234	—	Taller 16-inch
185/65R15	33	—	2.28	—	228	—	Small / older car

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	35 psi / 2.41 bar	36 psi / 2.48 bar
Motorway + luggage	36 psi / 2.48 bar	38 psi / 2.62 bar

Steering feel on the Zafira Tourer 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 Zafira Tourer

Measure before the school run, not after the M25.
Write LF / RF / RR / RL. Do not keep Zafira Tourer 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.

Temperature drift

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

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

Opel notes

No special Opel exception: the Zafira Tourer 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 Opel Zafira Tourer 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 Opel sticker and this page disagree, the sticker wins.

Questions about this Zafira Tourer

What is that in bar and kPa for the Zafira Tourer?

Mid-points are about 2.31 bar (231 kPa) front and 2.31 bar (231 kPa) rear.

Is the sidewall number correct on a Opel Zafira Tourer?

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

How often should I check a Zafira Tourer?

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

When does TPMS warn on a Opel Zafira Tourer?

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 Opel Zafira Tourer 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.
