There will be thw usual littny of 'run flats suck' and 'validte my choice and buy the tires I chose'..... I wont do that.

But two things.

1. Do you NEED run flat tires? ie Do you have a spare tire and jack in the car? yes or no.

2. Do you know your current alignment numbers???????????????


People onbcess over tires and 'how many mies I got', yet they blithely ignore their alignments. A bad alignment will accelaerate tire wear. In fact, a 'less than optimal' alignmnet, that is still INSIDE the BMW specs, can result in one half the life as compared to an optimal alignment.

So, first concept: an alignment isnt a 'binary thing', as in "I took it to BMW and they aligned it". They may, and it may still suck.

So, I will tell you were you want to INSIST they set your alignment:
0.01 to 0.02 TOE IN on each of the 4 wheels

Camber and caster at the middle of the BMW range, but MOST IMPORTANTLY, balanced side to side (ie on each axle, these should be roughly matching)

Just off the top of my head, I will say you will be very toed in. The rear your camber on the RR is extreeme, with much less on the LR. LR toe may be more. Your LF camber will be larger. This is just utter speculation.

Finally, DO NOT assume they know what they are doing. Dont just get it aligned. Set it to these numbers. Insist they agree to this as part of the job.
