Just switched the original runflat tyres around today on the wife cooper S
Shocked to see the rate of wear, fronts need changing now just 12k miles, the inside tyres are far more worn than the offside by a few mm.
What’s the consensus is this normal for the car looks to me like the tracking is way out front and rear. Is this normal for a cooper S, I thought my quattro was bad a 20k for a set but at least I get even tyre wear.

my fronts lasted just under 8k

1) Incorrect inflation.
2) tracking is off.

If you consider an over inflated tyre, then it's obvious the centre wears first as the tyre will buldge. But if you have bad tracking (and factory built cars DO have this quite often), then quite simply you are dragging your tyres for 1000's of miles unecessarily. Compare this to a tyre that rolls in perfect track, the only wear is on heavy braking and hard acceleration.

I drive fast, and have soft compounds. My tyres last ages !!!

The devil is in the detail unfortunately.

PS. I'd check your Oil and Coolant at least once a month too - the MCS oftens likes to drink oil

By way of comparison, I swapped my runflats on my R53 MCS front to rear at 14,500 miles. I reckon that they were halfway through their life, so should see around 29,000 out of the set.

The tracking on mine was perfect from the factory, but my experience of tracking on new cars is that they are wrong as often as they are right and the first pair of front tyres are often sacrificed in the process of finding out!

PS: I wouldn't normally recommend swapping front to rear, I just wanted the original set to wear out simultaneously so that it's easy to swap to something completely different.

I'll second that.

My Cooper never used any oil or water, while the Cooper S uses more than enough of each to not last the distance between services.

Pressures checked regularly along with oil and water, never much movement.
Must be tracking will see what dealer has to say Wednesday.
But from the few comments 12k miles appears to be excessive wear.

My first MINI was bought new in March 03, a Cooper Chilli with SS+.

It came with the Dunlop 17's which were far better grip than the Pirellis but wear out quickly.

That said my original rear tyres were only changed at 45K as one got a puncture and I replaced them with Pirellis which were far cheaper back then.

Pirelli's on the front lasted about 27K with about half wear before yet another puncture forced a swop of the fronts.

Original front Dunlops lasted a mere 12K.

note...no I didn't used to drive like a pansy, my cooper was such fun for 4 wheel drifting in the wet.

My "S" I bought had 1 previous owner and I picked it up with 6K on the clock and the fronts had already been changed !
So far I'm on the tyres that came on the car at 18K (therefore 12K plus previous owners and I have loads of tread left.
