When I say eating tyres, I changed the NSF tyre 3000 miles ago. Last week - what I didn't see was the inside edge being worn down to the cords, didn't see it of course until the tyre let go at 80mph. The rest of the tyre still had 5mm of tread on it !
When it went into the dealer on the back if a truck, the only tyre that hadn't worn the inside edge down to the cords was the rear tyre that I replaced only 1500 miles ago.
The wheel alignment has been checked three times, 2 by BMW dealers, and 1 by a specialist company that I used to align the wheels on my previous Porsches - the wheel alignment is absolutely spot-on.
After a week at the dealer, who has had 2 other customers with the same problems we escalated to BMW UK. Their response 'This is what 8-Series do when they are driven enthusiastically', and they have had many reports of this 'phenomenon' . Now, I like to drive quickly when the road permits, but here in the UK, it rarely does and most of the time this car is just gently cruising around.
I have had some cars in my time, and some that like to get through tyres, but none that would shred a front tyre in 3000 miles literally on one inside edge !
So after around £2.2k in tyres in 12000 miles, if you run any type of 8-Series - be aware guys ! I am of course going into battle with BMW over this, in my opinion this represents a safety issue. I am also going to switch to Michelin, I would got with Pilots, but don't want to keep putting good tyres on if they are just going to be shredded, so I am going to see if Super Sports will improve the situation.
So beware fellow 8ers, I love the car, but I cannot hang onto it at this rate ! Quite literally as it happens !

I have had exactly the same issue with my 850M
Having done 8500 miles. Two sets on the front and one set due iminently on the rear. BMW say it's a characteristic of the car.
When the tyres start to get worn on the front it starts to crab and jump on full lock.
Michelin now do tyres for the 850 so I will be swapping to those, as in my experience they normally last longer and dont have the tramlining, crabbing charactistics when they get to the last few mm of tread.
If anyone has any other intel or experience in resolving it please do let me know
