Mercedes-Benz GLC 43 AMG rear tyres: 32-35 psi / 2.2-2.4 bar

Drivetrain: all-wheel drive
Body: SUV / crossover
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

The rear of a SUV / crossover takes passengers, luggage and, on vans, payload. Catalogue rear pressure on the Mercedes-Benz GLC 43 AMG is 32-35 psi / 2.2-2.4 bar. 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.

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 (215/70R16 and others)

215/70R16 is the first planning size here. 225/65R17 is usually the plus-size or LT step. Keep load index at or above original equipment.

Tyre size	Front PSI	Rear PSI	Front bar	Rear bar	Front kPa	Rear kPa	Note
215/70R16	—	34	—	2.34	—	234	Compact crossover
235/65R17	—	36	—	2.48	—	248	Mid-size SUV
225/65R17	—	35	—	2.41	—	241	Very common 17-inch
255/50R20	—	37	—	2.55	—	255	20-inch plus-size
245/60R18	—	37	—	2.55	—	255	Heavier CUV
245/55R19	—	36	—	2.48	—	248	Low-profile 19-inch
225/60R18	—	35	—	2.41	—	241	Highway CUV
235/60R18	—	36	—	2.48	—	248	Plus-size 18-inch

Pressure against load

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	38 psi / 2.62 bar

A family SUV / crossover 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 GLC 43 AMG.

How to set the GLC 43 AMG

Park the Mercedes-Benz GLC 43 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 all-wheel drive GLC 43 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 GLC 43 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 GLC 43 AMG is actually occupied that day.

Spare and inflator kit

A matching full-size spare on the Mercedes-Benz GLC 43 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 GLC 43 AMG

What PSI if I plus-size toward 225/65R17?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 215/70R16, 235/65R17 and 225/65R17 as a planning band.

How often should I check a GLC 43 AMG?

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

Front versus rear on the Mercedes-Benz GLC 43 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 tyre pressure should a Mercedes-Benz GLC 43 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.

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.
