W211 (E-Class) Saloon - tyre pressures when towing?

[Gollom]

Checked the manual and there is no information regarding what should be used whan towing a trailer. Should I use the "fully laden" pressures or "normal" pressures? There will only be 2 of us in the car and no luggage

Now why would you want to be towing anything?



In theory, the trailer should be balanced front-to-rear, so you should not have to do anything with your rear tyres. However, adding 5psi should ensure some safety margin in case the trailer is a little front-heavy.

I tow with pressures set as per the fully-laden pressure.

If there's anything heavy in the trailer - albeit not luggage - if it's clean and safe to do so then it may be worth carrying it in the boot to aid stability.
