M135i Tyre Wear
Discussion
I've just had all 4 tyres replaced on my M135i by an independent tyre supplier/fitter having had the car fully serviced at my BMW supplying dealer. They've been replaced with the standard fit Michelin Pilot Super Sports, not run flats 225/40 ZR18.
The old front tyres show excessive wear on the shoulders, both on the inside and outside of both left and right tyres, necessitating the change.
I've queried this with BMW and they've concluded that I have been driving with incorrect and low tyre pressures. I check the tyre pressures with a gauge every month or so (re-inflating them when needed to manual prescribed pressures) and visually inspect them every time I walk up to the car. The tyres have kept their pressure well and I have only needed to top them up on a couple of occasions in the last 18 months. The car is also fitted with BMW's Flat Tire Monitor (FTM) system which I know works but has not alerted me to any issues recently.
BMW want £320 to realign the geometry despite the car having just been serviced in full.
Has anybody had any similar experiences of odd tyre wear on their BMW or specifically M135i which has potentially been mis diagnosed by BMW requiring an expensive and unnecessary geometry alignment?

Thank you for all of the replies, to clarify - the original tyres were the standard fit Michelin Pilot Super Sports (Sir Dave - your assumption was correct), they are not run flat tyres and have not been driven under inflated.
I’ve just been reading the Michelin website which shows the dual compound detail, I wasn’t aware of this, however I still feel the excessive wear remains rather surprising.
Sounds like the best bet may be an independent alignment to limit the chances of it reoccurring.
