The DS I believe only has a towball weight of up to 150kg (we have to have at least 10% down weight in Australia). The Freelander has up to 350kg (Australia) & you can increase GVM by 100kg when towing up to 100kph. So out the back of the Freelander it can cope with a lot more load thus the tyres will need to be a bit higher pressure. So probably why they are the same as the front. Procrastination, mankind's greatest labour saving device!
