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

European and UK handbooks usually quote bar. The Mercedes-Benz Maybach GLS catalogue is 2.2-2.4 bar front and 2.2-2.4 bar rear (midpoint 2.31 / 2.31). TPMS typically warns near 25 psi (about 25% below target). That is already a soft tyre, not a fill target. Keep side-to-side spread inside about 2 psi so the all-wheel drive hardware is not working on a radius mismatch.

Mercedes-Benz Maybach GLS placard versus sidewall

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

Estimated pressure by tyre size (215/70R16 and others)

If your Mercedes-Benz Maybach GLS no longer wears the OEM diameter, start at the row nearest 215/70R16 or 255/50R20 and confirm with the tyre maker’s load table.

Tyre size	Front PSI	Rear PSI	Front bar	Rear bar	Front kPa	Rear kPa	Note
215/70R16	34	34	2.34	2.34	234	234	Compact crossover
255/50R20	37	37	2.55	2.55	255	255	20-inch plus-size
245/55R19	36	36	2.48	2.48	248	248	Low-profile 19-inch
235/60R18	36	36	2.48	2.48	248	248	Plus-size 18-inch
235/65R17	35	36	2.41	2.48	241	248	Mid-size SUV
245/60R18	36	37	2.48	2.55	248	255	Heavier CUV

Load notes

Load moves the rear of a SUV / crossover 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

How to set the Maybach GLS

Measure before the school run, not after the M25.
Write LF / RF / RR / RL. Do not keep Maybach GLS 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.
Log date, ambient temperature and the four readings.

Temperature drift

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

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 Maybach GLS is actually occupied that day.

Spare and inflator kit

A matching full-size spare on the Mercedes-Benz Maybach GLS 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.

Keep the Mercedes-Benz Maybach GLS on the printed band; use 215/70R16 and 245/55R19 only as a map for non-OEM wheels.

Questions about this Maybach GLS

What is that in bar and kPa for the Maybach GLS?

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

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 Maybach GLS?

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

What tyre pressure should a Mercedes-Benz Maybach GLS 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 245/55R19?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 215/70R16, 255/50R20 and 245/55R19 as a planning band.
