It's likely the rear tyres were on the front before you got the car, due to the wear on them.
The front is toeing out, so a simple alignment check will rectify this.
First though I would check all bushes etc for wear, if worn put poly ones on, then get tracking adjusted, low ride height will cause more camber, but it is toe that kills inner edges not camber.
The rear suspension has a natural toe out, which is a disaster for performance, but some inexpensive R&B shims correct some of this, not all by any means, but a worthwhile improvement for around £10.
