I too think its wheel alignment, the scrub to wear out two set of normally driven tyres in 10k miles should be able to be seen by simply measuring the distance between the wheels front and back, you'd be surprised just how accurate measuring inside can be, i used to use two narrow gauge copper pipes one a sliding fit inside the other for measuring this way, easy DiY, assume parallel unless you know the correct figure, probably slight toe out is specified.

A useful guide to telling if your steering wheels are out of alignment whilst driving is to put one side of the car onto continual white painted lines on a wet road, usually the white line has less grip so the car should pull slightly one way or the other when one side only encounters less grip...undulating roads that exercise the suspension often produce similar wanderings if things are not right.

If the car had been in a serious enough accident to push the geometry out of line i think you'd feel it in normal driving, by steering pulling one way, the vehicle crabbing, or having too much or too little self centring action, and it would probably feel most unpleasant in the wet.

Other than that, do you have to negotiate dozens of roundabouts, modern cars corner very quickly whilst not feelingat all uncomfortable, as Railroad mentions tyre pressures are important.

If the wear is only on the inside edges of both tyres the problem has to be wheel alignment, the wheels are towing out.
