I recently bought a 987S with 19" wheels fitted with the original Michelen PS N1 tyres, the car has covered 14k miles. I noticed that they are all wearing on the outside edge, but especially on the front left. There is a lot of tread left in the middle and inside. My first thought was the pressure, but when I checked they were at 31 psi front and 35 psi rear, so only 1 off the Porsche recommended levels. Unfortunately I don't know what they were like before I got the car but they were at this level when I picked it up. Is this likely down to incorrect pressure or maybe a symptom of something else? Also, would the wear on the outside make the tyre illegal in the UK even though there is lots of tread on the middle and inside? What would be the recommended minimum tread on the outside before replacing them? Thanks in advance
