Rear tyre wear issues

[Mark and Cath]

Our 2010 Verso has 5 or 6mm of tread left in the middle of the rear tyres but the nearside tyre is down to canvas on the outer edge.  Does the rear axle have tracking on the Verso?  Any ideas what is causing it before I put 2 new tyres on?  Thanks.

Tread in the middle = under inflated, Outer edge is a camber depending on how bad it is it could be shimmed

2 new tyres and get a proper 4 wheel alignment on a rack

Is the rear camber adjustable without shims or is it fixed and we have bent a stub axle or something?  Cheers.

its fixed (not adjustable via a tie rod) but can be shimmed, you can't really tell until you get a 4 wheel alignment done, if its too far out of spec it's a new rear beam
