De la Chapelle Atalante 57S inflation in PSI (32-35 front, 32-35 rear)

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

If a Atalante 57S owner asks “what PSI?”, start at 34 at the steering axle and 34 at the rear, then confirm the placard. Size estimates on this page include 185/65R15, 195/65R15 and 225/50R17 — interpolated from the catalogue midpoint, not a second factory sticker.

Estimated pressure by tyre size (185/65R15 and others)

If your De la Chapelle Atalante 57S no longer wears the OEM diameter, start at the row nearest 185/65R15 or 195/65R15 and confirm with the tyre maker’s load table.

Tyre size	Front PSI	Rear PSI	Front bar	Rear bar	Front kPa	Rear kPa	Note
185/65R15	33	33	2.28	2.28	228	228	Small / older car
195/65R15	34	34	2.34	2.34	234	234	Very common compact

How to set the Atalante 57S

Park the De la Chapelle Atalante 57S 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 Atalante 57S is enough to feel a pull.
Refit valve caps and reset TPMS if the handbook asks for a relearn.

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	37 psi / 2.55 bar

Temperature drift

Roughly 1 psi per 5–6 °C. The table uses 34 psi as a 20 °C baseline for this Atalante 57S.

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

De la Chapelle notes

No special De la Chapelle exception: the Atalante 57S 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 De la Chapelle Atalante 57S 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 De la Chapelle sticker and this page disagree, the sticker wins.

Questions about this Atalante 57S

When does TPMS warn on a De la Chapelle Atalante 57S?

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

What PSI if I plus-size toward 225/50R17?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 185/65R15, 195/65R15 and 225/50R17 as a planning band.

Is the sidewall number correct on a De la Chapelle Atalante 57S?

No. Sidewall PSI is a maximum. The Atalante 57S placard is the operating target, near 32-35/32-35 psi.

What tyre pressure should a De la Chapelle Atalante 57S 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 Atalante 57S?

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