Too tyred...
Just went to get a puncture repair and had three new tyres! 5 month old STi with 5k miles. 3mm left on the fourth. Is this normal or am I doing something wrong? The Potenzas were all worn on the inside edge.

Inside edge wear on the front would indicate a variation of the 'Prodrive' toe-in setting to minimise understeer. Although this makes the handling/turn-in better, it is known to wear the tyres a bit more. However, 5K in 5months (assuming tyres from new?) seems excessive to me. Maybe worth checking the geom or slow down around corners .

Regarding the uneven wear, it's not uncommon for Imprezas. You might what to consider getting you geometry set to Prodrive settings by someone like PowerStation, may improve the tyre wear. The tolerances as they come out of the factory are pretty wide.

Cheers - must admit I was concerned with only three of the four being replaced - was going to check with the dealer. This is the probelm with it being a company car....the authorisers are incentivsed on keeping maintenance costs down

Agreed though - if the repaired tyre has low tread deptth, having a such a wide disparity between treads in a 4WD, especially on the same axle, is not recommended!

(ps. It'll knacker the diff)
I had this argment with my company a year or so back and eventually won when I asked them to put the instruction to only replace one tyre in writing before I would do it.
