Until recently everything felt fine, I had a slow puncture about 2 weeks ago (it didn't go flat), since getting it repaired the steering feels a bit 'vague', but it may be my imagination. The car drives straight (I can take hands off wheel with no wondering) but I think the steering wheel is a bit off centre.
I had new tyres and rims fitted on Friday and put the old wheels/tyres in my shed, when I looked carefully at the tread on the front wheels I noticed that the innermost rib on both tyres was worn quite badly across half the rib, I don't know if this is recent wear or not. I'm going to get the tracking checked soon.
