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

2.3 bar is not 23 psi. On this ML 63 AMG 2.2-2.4 bar converts to about 32-35 psi. Use the table, not a guess. Size estimates on this page include 225/45R17, 245/40R18 and 255/35R18 — interpolated from the catalogue midpoint, not a second factory sticker.

Mercedes-Benz ML 63 AMG placard versus sidewall

If the Mercedes-Benz sticker is painted over, the handbook is next. This website is a map, not a replacement VIN label.

Estimated pressure by tyre size (225/45R17 and others)

If your Mercedes-Benz ML 63 AMG no longer wears the OEM diameter, start at the row nearest 225/45R17 or 245/40R18 and confirm with the tyre maker’s load table.

Tyre size	Front PSI	Rear PSI	Front bar	Rear bar	Front kPa	Rear kPa	Note
225/45R17	34	35	2.34	2.41	234	241	Front sport size
245/40R18	35	36	2.41	2.48	241	248	Square-ish sport
255/35R18	35	36	2.41	2.48	241	248	Rear stagger 18-inch
235/35R19	36	36	2.48	2.48	248	248	Front 19-inch
225/40R18	35	35	2.41	2.41	241	241	Front 18-inch
255/40R17	35	36	2.41	2.48	241	248	Rear stagger 17-inch
275/30R19	36	37	2.48	2.55	248	255	Rear 19-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	35 psi / 2.41 bar	36 psi / 2.48 bar
Motorway + luggage	36 psi / 2.48 bar	38 psi / 2.62 bar

How to set the ML 63 AMG

Park the Mercedes-Benz ML 63 AMG 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 rear-wheel drive ML 63 AMG 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 ML 63 AMG.

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

Mercedes-Benz notes

Mercedes often lists comfort versus load. Match the table to how the ML 63 AMG is actually occupied that day.

Spare and inflator kit

A matching full-size spare on the Mercedes-Benz ML 63 AMG 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 Mercedes-Benz sticker and this page disagree, the sticker wins.

Questions about this ML 63 AMG

Should I bleed pressure after a motorway run?

No. Heat raises the gauge. Set cold only. Bleeding a hot tyre leaves it low the next morning.

Is the sidewall number correct on a Mercedes-Benz ML 63 AMG?

No. Sidewall PSI is a maximum. The ML 63 AMG placard is the operating target, near 32-35/32-35 psi.

Front versus rear on the Mercedes-Benz ML 63 AMG?

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.

What PSI if I plus-size toward 255/35R18?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 225/45R17, 245/40R18 and 255/35R18 as a planning band.

What tyre pressure should a Mercedes-Benz ML 63 AMG 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.
