On the front tyres the inner are down to the nylon, the outsides have very good tread. What should be considered in trying to minimise this as I am replacing all four this week.
Thanks

on my experience but I will repeat it here.
This tyre wear pattern is not cosistent across the thread. Only the inner 20mm or so gets badly worn while the rest is evenly worn. I don't think it is camber or tracking because the effects of these are usually proportional across the whole tread.
In my case, the front wishbone bushes were badly worn, causing severe toe out under breaking - hence the wear pattern. At rest, on the ramps, the tracking and camber were checked and were in spec. Fitting new ones was not a painless task but worth doing for the new tyres.
The "spec" is so wide, its almost useless. Maybe some arse covering going on from the fitter perhaps? Worth a trip to wim for a demo?
For me the tyre has to be at an angle to wear
on one side. If it was just toe and the tyre was flat to the ground it would wear evenly but more quickley... ?? As i understand it.
