Front axle PSI and bar on the Chamonix Others

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

The front axle of a Chamonix Others steers and, on front-wheel drive cars, often pulls as well. Catalogue front pressure is 32-35 psi / 2.2-2.4 bar. Size estimates on this page include 245/40R18, 225/45R17 and 255/40R19 — interpolated from the catalogue midpoint, not a second factory sticker. Battery mass on this {make} {model} makes a 4 psi-low tyre cost range as well as heat.

Chamonix Others placard versus sidewall

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

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

Planning cold pressures for sizes often seen on a passenger car. This Others sample opens with 245/40R18, then 225/45R17 and 255/40R19.

Tyre size	Front PSI	Rear PSI	Front bar	Rear bar	Front kPa	Rear kPa	Note
245/40R18	36	—	2.48	—	248	—	Wide touring 18-inch
225/45R17	35	—	2.41	—	241	—	Sport 17-inch
255/40R19	37	—	2.55	—	255	—	EV 19-inch aero wheel
235/45R18	36	—	2.48	—	248	—	Common EV 18-inch
185/65R15	33	—	2.28	—	228	—	Small / older car

195/65R15	34	—	2.34	—	234	—	Very common compact

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	34 psi / 2.34 bar	35 psi / 2.41 bar
Motorway + luggage	35 psi / 2.41 bar	37 psi / 2.55 bar

Steering feel on the Others lives on this axle. Do not drop front pressure to “soften” a plus-size 255/40R19; you will roll the sidewall in a roundabout.

How to set the Others

Park the Chamonix Others 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 Others is enough to feel a pull.
Refit valve caps and reset TPMS if the handbook asks for a relearn.

Temperature drift

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

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

Chamonix notes

No special Chamonix exception: the Others 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 Chamonix Others 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 Others than nitrogen upsells.

Questions about this Others

What PSI if I plus-size toward 255/40R19?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 245/40R18, 225/45R17 and 255/40R19 as a planning band.

Is the sidewall number correct on a Chamonix Others?

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

What is that in bar and kPa for the Others?

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

What tyre pressure should a Chamonix Others 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.

When does TPMS warn on a Chamonix Others?

Direct TPMS typically flags about 25% below placard — near 25 psi on this row. Fill to the sticker, not to the lamp.
