Mercedes-Benz CLK front tyre pressure

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 front

2.31 bar · 231 kPa at the steering axle

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

A 3 psi miss on one front corner of this CLK shows up as a wander before the TPMS lamp bothers you. Target 34 psi (2.31 bar) cold. Under-inflation cooks the shoulders of a CLK; over-inflation wears the centre rib and bangs every cat’s eye.

Mercedes-Benz CLK placard versus sidewall

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

Estimated pressure by tyre size (185/65R15 and others)

If your Mercedes-Benz CLK no longer wears the OEM diameter, start at the row nearest 185/65R15 or 205/60R16 and confirm with the tyre maker’s load table.

Tyre size	Front PSI	Rear PSI	Front bar	Rear bar	Front kPa	Rear kPa	Note
185/65R15	33	—	2.28	—	228	—	Small / older car
205/60R16	34	—	2.34	—	234	—	Taller 16-inch
225/50R17	35	—	2.41	—	241	—	Touring 17-inch
215/55R16	34	—	2.34	—	234	—	Slightly wider 16-inch
205/55R16	34	—	2.34	—	234	—	Typical mid-compact OEM
245/40R18	36	—	2.48	—	248	—	Wide touring 18-inch
225/40R18	36	—	2.48	—	248	—	Low-profile 18-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	38 psi / 2.62 bar

Steering feel on the CLK lives on this axle. Do not drop front pressure to “soften” a plus-size 225/50R17; you will roll the sidewall in a roundabout.

How to set the CLK

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

PSI, bar and kPa

PSI-led conversions for the Mercedes-Benz CLK band (32-35 / 32-35).

PSI	Bar	kPa
30	2.07	207
32	2.21	221
33	2.28	228
33.5	2.31	231

Temperature drift

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

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 CLK is actually occupied that day.

Spare and inflator kit

A matching full-size spare on the Mercedes-Benz CLK 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 CLK than nitrogen upsells.

Questions about this CLK

Front versus rear on the Mercedes-Benz CLK?

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 CLK 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 225/50R17?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 185/65R15, 205/60R16 and 225/50R17 as a planning band.

Is the sidewall number correct on a Mercedes-Benz CLK?

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

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.
