You are right Griff, my Dodge has only 2 reartires :-) I have changed the rims from 16.5 to 16 zoll and bought tires for light trucks with letter C at the end of the size indication ("c" for commercial or cargo).
They have 2 load capacity indices, 1 when using as single tires and the 2. for dual tires.
Have your rear axle loading weighed. Most highway departments and law enforcement agencies have scales that can weigh individual axle loads. Most will do it for free, especially if they understand you want it done due to safety concerns.
Truckers in truck stops and coffee shops can tell you where to go to have it done. At a minimum, offer to pay for their coffee or meal. (It's an unwritten matter of social protocol ... and the info you'll get is worth more than the cost of a meal or round of coffee.) A lot of the info I post on this thread originally came from truckers and truck mechanics.
I know this works in North America and should work in Europe. (Vehicle weight enforcement may actually be more stringent in Europe, so it may be easier for you.)
If your rear axle weight load is more than 75 percent of the load capacity of the tires, you're on thin ice.
