Mercedes-Benz · G 65 AMG · Rear

Mercedes-Benz G 65 AMG rear tyres: 32-35 psi / 2.2-2.4 bar

Drivetrain: rear-wheel drive
Body: passenger car
PSI F / R: 32-35 / 32-35
Bar F / R: 2.2-2.4 / 2.2-2.4

psi rear

2.31 bar · 231 kPa at the rear axle

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

Loaded G 65 AMG rears often need the sticker’s second column, not a copy of the front 32-35 psi figure. Under-inflation cooks the shoulders of a G 65 AMG; over-inflation wears the centre rib and bangs every cat’s eye.

Mercedes-Benz G 65 AMG placard versus sidewall

Sidewall PSI is a carcass maximum. Recommended operating pressure for this G 65 AMG is the pillar sticker, near 34/34 psi.

Estimated pressure by tyre size (275/30R19 and others)

Planning cold pressures for sizes often seen on a passenger car. This G 65 AMG sample opens with 275/30R19, then 255/40R17 and 245/40R18.

Tyre size	Front PSI	Rear PSI	Front bar	Rear bar	Front kPa	Rear kPa	Note
275/30R19	—	37	—	2.55	—	255	Rear 19-inch
255/40R17	—	36	—	2.48	—	248	Rear stagger 17-inch
245/40R18	—	36	—	2.48	—	248	Square-ish sport
225/45R17	—	35	—	2.41	—	241	Front sport size
275/35R18	—	37	—	2.55	—	255	Wide rear
235/35R19	—	36	—	2.48	—	248	Front 19-inch
225/40R18	—	35	—	2.41	—	241	Front 18-inch
255/35R18	—	36	—	2.48	—	248	Rear stagger 18-inch

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

A family passenger car with a boot full of luggage should use the laden rear figure if Ford, VW or Mercedes printed one. Otherwise the modest steps in the load table are only a sketch for this G 65 AMG.

How to set the G 65 AMG

Measure before the school run, not after the M25.
Write LF / RF / RR / RL. Do not keep G 65 AMG 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.

Temperature drift

Roughly 1 psi per 5–6 °C. The table uses 34 psi as a 20 °C baseline for this G 65 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 G 65 AMG is actually occupied that day.

Spare and inflator kit

A matching full-size spare on the Mercedes-Benz G 65 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.

A cheap gauge and a monthly habit will do more for this G 65 AMG than nitrogen upsells.

Questions about this G 65 AMG

When does TPMS warn on a Mercedes-Benz G 65 AMG?

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

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.

What tyre pressure should a Mercedes-Benz G 65 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.

Is the sidewall number correct on a Mercedes-Benz G 65 AMG?

No. Sidewall PSI is a maximum. The G 65 AMG placard is the operating target, near 32-35/32-35 psi.

How often should I check a G 65 AMG?

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