all four tyres on my car are showing signs of additional wear on the shoulders relative to the centre of the tyre. (Approx extra 0.8mm per 8000miles)

If its on both the inside and outside edges its probably just a charisteristice of a large, heavy car.

If its only on one edge get the alignment checked, preferably by a reputable company that can do all 4 wheels. Forget dealers, they usually farm the work out, forget Kwik Fit etc. they don't have the necessary kit or even the expertise.

But don't forget that tyres have a hard life on a 4 x 4. As I said above they are large and heavy and when manouvering/parking there is a fair bit of tyre scrub.

If there is a XC 90 Forum it would be worth asking the same question on there, its possibly normal for this model.
