Mrk 4 Focus ST Michelin ps4s tyre wear.

[John Humpo]

Has anyone had issues with front tyres wearing on the inside, both my fronts have the canvas showing approx the same on either side they have done 27,000 km's & been rotated front to back every 7,500km's the vehicle has not been tracked or driven excessively hard as in cornering etc it is a late 2020 SA Mrk 4 ST so just gone 2yrs old, I was really surprised to see this amount of wear the tread in the centre of the tyre is fine still well above the wear markers
I have not hit any pot holes etc that would cause an alignment issue & it steers straight when on level ground, I am replacing the tyres within the next week & will obviously have the alignment checked, all I can think of is to much negative camber or toe out or both, what camber do they run from factory? I saw something that said anywhere from 0 to -1.6, thanks for any info.
