All the tyers are the same. Pretty sure on correct sides too. I think they've still got plenty of tread left (50%) but I might take a look just in case. It's a good idea though.

That doesn't sound good at all, I could take a look at that next time it happens. The rain yesterday afternoon was enough to trigger this problem. I noticed that if I don't stop driving, it'll come and go. Sometimes it'll sound terrible and sometimes it'll sounds perfectly fine. I unfortunately won't get to swap the wheels around until the weekend, I don't have a spare tyre to use when swapping them, or a jack for that matter :P I'll take a look at some of the ideas you guys have provided and take a look.
