This rear-wheel drive passenger car is filed here with a working range of 32-35/32-35 psi. The pillar sticker on your VIN still overrides the website. Size estimates on this page include 235/35R19, 225/45R17 and 275/35R18 — interpolated from the catalogue midpoint, not a second factory sticker.
Estimated pressure by tyre size (235/35R19 and others)
235/35R19 is the first planning size here. 275/35R18 is usually the plus-size or LT step. Keep load index at or above original equipment.

How to set the SL 60 AMG
- Measure before the school run, not after the M25.
- Write LF / RF / RR / RL. Do not keep SL 60 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.
- Log date, ambient temperature and the four readings.
PSI, bar and kPa
1 bar ≈ 14.5 psi; 1 psi ≈ 6.89 kPa. Mid-points on the SL 60 AMG: 34 psi = 2.31 bar = 231 kPa.
| PSI | Bar | kPa |
|---|---|---|
| 30 | 2.07 | 207 |
| 32 | 2.21 | 221 |
| 33 | 2.28 | 228 |
| 33.5 | 2.31 | 231 |
| 35 | 2.41 | 241 |
| 36 | 2.48 | 248 |
| 38 | 2.62 | 262 |
| 40 | 2.76 | 276 |
| 44 | 3.03 | 303 |
| 50 | 3.45 | 345 |
| 60 | 4.14 | 414 |
Spare and inflator kit
A matching full-size spare on the Mercedes-Benz SL 60 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.
Mercedes-Benz SL 60 AMG placard versus sidewall
Sidewall PSI is a carcass maximum. Recommended operating pressure for this SL 60 AMG is the pillar sticker, near 34/34 psi.
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 | 35 psi / 2.41 bar | 36 psi / 2.48 bar |
| Motorway + luggage | 36 psi / 2.48 bar | 36 psi / 2.48 bar |
Temperature and a cold gauge
Roughly 1 psi per 5–6 °C. The table uses 34 psi as a 20 °C baseline for this SL 60 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 SL 60 AMG is actually occupied that day.
Keep the Mercedes-Benz SL 60 AMG on the printed band; use 235/35R19 and 275/35R18 only as a map for non-OEM wheels.

Questions about this SL 60 AMG
Is the sidewall number correct on a Mercedes-Benz SL 60 AMG?
No. Sidewall PSI is a maximum. The SL 60 AMG placard is the operating target, near 32-35/32-35 psi.
What tyre pressure should a Mercedes-Benz SL 60 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.
What is that in bar and kPa for the SL 60 AMG?
Mid-points are about 2.31 bar (231 kPa) front and 2.31 bar (231 kPa) rear.
Front versus rear on the Mercedes-Benz SL 60 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.
How often should I check a SL 60 AMG?
Monthly, before a long trip, and after a 10 °C weather swing. Include a full-size spare.
