If a SLK 32 AMG owner asks “what PSI?”, start at 34 at the steering axle and 34 at the rear, then confirm the placard. TPMS typically warns near 25 psi (about 25% below target). That is already a soft tyre, not a fill target.
Mercedes-Benz SLK 32 AMG placard versus sidewall
The tyre-information placard on a Mercedes-Benz SLK 32 AMG 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 (275/30R19 and others)
Planning cold pressures for sizes often seen on a passenger car. This SLK 32 AMG sample opens with 275/30R19, then 255/35R18 and 255/40R17.

How to set the SLK 32 AMG
- Park the Mercedes-Benz SLK 32 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 rear-wheel drive SLK 32 AMG is enough to feel a pull.
- Refit valve caps and reset TPMS if the handbook asks for a relearn.
Load notes
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 |
Temperature drift
Roughly 1 psi per 5–6 °C. The table uses 34 psi as a 20 °C baseline for this SLK 32 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 SLK 32 AMG is actually occupied that day.
Spare and inflator kit
A matching full-size spare on the Mercedes-Benz SLK 32 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 SLK 32 AMG than nitrogen upsells.

Questions about this SLK 32 AMG
How often should I check a SLK 32 AMG?
Monthly, before a long trip, and after a 10 °C weather swing. Include a full-size spare.
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 is that in bar and kPa for the SLK 32 AMG?
Mid-points are about 2.31 bar (231 kPa) front and 2.31 bar (231 kPa) rear.
Is the sidewall number correct on a Mercedes-Benz SLK 32 AMG?
No. Sidewall PSI is a maximum. The SLK 32 AMG placard is the operating target, near 32-35/32-35 psi.
Front versus rear on the Mercedes-Benz SLK 32 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.
