Hi gents (and ladies?)
Would you believe it, having said that my fronts were wearing much better than the rears, I had a shocker. As I was getting in to the car last night I noticed that the driver side front had worn on the outer edge down to the fabric. Scary, I hadn't noticed it at all until it got that far and I drive up and down the motorway at motorway speeds (ahem) almost every day.
Had to take it to KwikFit (the cheapest in the locality, my office is in Chesterfield at the moment by a margin) - £328 for a pair of Goodyear F1 Asymmetric, so now I have the same all round. When the Michelins were taken off I checked them and on both the outer edge was very worn, with progressively less wear going in. The middle of the tyres had around 4mm still on them so a bit annoyed to change them when so much of the tyre is good.
Some views on tyre pressures - I had them under 2bar for ride comfort but got KwikFit to put all four up to 2.1bar (around 32psi). The rears were down at 26psi, way too low (my fault, I wanted a softer ride). Anyway a fairly expensive lesson learned in terms of tyre pressures. Ho hum.
I think it is a common trait that one edge wears much quicker than the other due to the geometry of these cars? Although I seem to recall that people have also had inside wear which is very difficult to spot of course...
