The offside rear tyre on my trusty P-reg 306 1.9TD has started to rub against the inside wheelarch. Not badly, but enough that there's a slight mark on the tyre. Is there any adjustment to ride height as it does seem a little lower at the back than I remember it? The back end has groaned a bit at the back for a week or so, and when the weather has been dry there's also been a squeak. Both occur when you push the back end down or lift it up and when driving at walking pace, faster and they disappear. Any ideas? It doesn't seem to be affecting the handling, still drives like it's on rails. I'm just concerned that the rubbing isn't going to do the tyre any good. Cheers, Derek
