Question from visitor, 08/01/2010 :What is the maximum tyre pressure for a vehicle carrying a heavy load?
Answer by rezulteo, 08/01/2010 :

You have 2 different pressure indicators in the owners handbook: if your vehicle is loaded use the pressure indicator marked "vehicle fully laden or on motorway" which is higher than the normal tyre pressure.
