Tire Life
 

For those who have replaced tires, how many miles did you get on the OEM's and did you stick with the same brand when you got new ones?

For the previous E70 with the same spec 21" 215s, approximately 50,000kms - not sure if this will be applicable to the E71 M. Hope this helps.

Cheers,

I realize not what you are asking but I just hit 10K miles and about half tread left. I hope to make it to 20K but not sure. When I replace I think I am putting on Michelin non runflat Diamaris's or Tour HP's not sure yet.

i had to replace mine at about 15k and i went with the same tires that the car came with.

Thanks for the feedback.
Is there a lot of difference between the Run Flats and non?

Ride will be a bit different and tire life will be different as well. I replaced runflats on my 545 sport to Michelin PS2's and could not have been happier. Runflats on this are much better than those Gen1 Dunlops but still I will likely switch these out this time around.
