Rear axle PSI and bar on the Mercedes-Benz CL 160

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 CL 160 rears often need the sticker’s second column, not a copy of the front 32-35 psi figure. A 10 °C overnight drop takes roughly 1 psi (0.07 bar) off a closed Mercedes-Benz tyre.

Mercedes-Benz CL 160 placard versus sidewall

The tyre-information placard on a Mercedes-Benz CL 160 sits on the driver’s door pillar (sometimes the fuel-filler flap). Catalogue figures here are a general band: 32-35 / 32-35 psi.

Estimated pressure by tyre size (245/40R18 and others)

245/40R18 is the first planning size here. 215/50R17 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
245/40R18	—	36	—	2.48	—	248	Wide touring 18-inch
215/55R16	—	35	—	2.41	—	241	Slightly wider 16-inch
215/50R17	—	35	—	2.41	—	241	Plus-size 17-inch
225/50R17	—	35	—	2.41	—	241	Touring 17-inch
185/65R15	—	33	—	2.28	—	228	Small / older car
205/60R16	—	34	—	2.34	—	234	Taller 16-inch
225/45R17	—	35	—	2.41	—	241	Sport 17-inch
195/65R15	—	34	—	2.34	—	234	Very common compact

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	36 psi / 2.48 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 CL 160.

How to set the CL 160

Park the Mercedes-Benz CL 160 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 CL 160 is enough to feel a pull.
Refit valve caps and reset TPMS if the handbook asks for a relearn.

PSI, bar and kPa

PSI	Bar	kPa

Temperature drift

Roughly 1 psi per 5–6 °C. The table uses 34 psi as a 20 °C baseline for this CL 160.

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 CL 160 is actually occupied that day.

Spare and inflator kit

A matching full-size spare on the Mercedes-Benz CL 160 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 CL 160

When does TPMS warn on a Mercedes-Benz CL 160?

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

Front versus rear on the Mercedes-Benz CL 160?

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.

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.

How often should I check a CL 160?

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

What PSI if I plus-size toward 215/50R17?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 245/40R18, 215/55R16 and 215/50R17 as a planning band.
