Uneven tyre wear on rear of Alfa 147!! Sign of a bigger problem?

The outside edges of just my rear tyres are wearing quicker than the inside. Is this a sign of a bigger problem that needs attention..

Ps. the car is an 1.6 147.

Thanks

Get your wheel alignment checked out. And also ensure tyres are ran at the correct pressure. If this returns no results I think it could be a sign of suspension woes.

This is normally the case when the suspension busshes are worn out.
