o/s looks like its been slightly over inflated as the very inner edge is still there all be it with the wear off set. n/s looks quite bad.

did you have those tyres from new? was the car lowered with those tyres mostley worn?

i think you will see better tyre wear now but fitting the camber adjusting bolts will certainly mean both sides can be brought bang on spec. just be aware that original bolts tend to sieze into the bushes making it impossible to get out so the only way is to cut them and either replace the bushes with poly or buy new arms and bolts as you can't buy the rubber bushes seperate, well not from ford anyway.
