Cold means the Talbot Matra Murena has stood at least three hours, or covered less than about a mile. Heat from a dual carriageway run is not the number you set. Size estimates on this page include 245/40R18, 205/60R16 and 215/55R16 — interpolated from the catalogue midpoint, not a second factory sticker.

Temperature and a cold gauge

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

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 Matra Murena

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

Talbot Matra Murena placard versus sidewall

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

Estimated pressure by tyre size (245/40R18 and others)

If your Talbot Matra Murena no longer wears the OEM diameter, start at the row nearest 245/40R18 or 205/60R16 and confirm with the tyre maker’s load table.

Tyre size	Front PSI	Rear PSI	Front bar	Rear bar	Front kPa	Rear kPa	Note
245/40R18	36	36	2.48	2.48	248	248	Wide touring 18-inch

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

Talbot notes

No special Talbot exception: the Matra Murena 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 Talbot Matra Murena 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 Talbot sticker and this page disagree, the sticker wins.

Questions about this Matra Murena

What is that in bar and kPa for the Matra Murena?

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

What tyre pressure should a Talbot Matra Murena 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.

What PSI if I plus-size toward 215/55R16?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 245/40R18, 205/60R16 and 215/55R16 as a planning band.

Front versus rear on the Talbot Matra Murena?

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 Talbot Matra Murena?

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