Tyre Pressure

[Willy100]

The suggested tyre pressures on the fuel flap refer to R18 wheels only on my SLK 350 R171. No other information on the car and nothing I can see in the book. My car has R17 tyres, does anyone know the recommended pressures please?

Use the pressures from the fuel flap. Only extreme changes in wheel and tyre size would require the tyre pressures to be changed. Go with what’s in the flap, monitor wear and then fine tune.
