Wear of the tires of E70 with regard to E53

After several exchanges on French and German forums with owners of X5, it seems very clear that tyres pneumatics wear out much more fast on X5 E70 than on X5 E53.

With my E53, I had crossed 50.000 kilometres (31.000 miles) with Michelin Diamaris before replacing them. With E70 it is impossible to exceed 30.000 kilometres (18.600 miles).

The technology run flat seems cause (more important weight of the tire, the more important heating of the tread) there but do not you think that this wear is also due to a bad regulation of rolling trains how it was the case for the Tuareg or the Q7 ?

Any of you have they information of BMW on this subject?

The RFTs on my e92 easily got 20k+ miles (high performance) before I sold them. They were still quiet and had plenty of thread left (I'm sure another 15-20k miles). I'm pretty rough on tires, so I was actually pleased. I usually wear our high performance tires after about 20k miles. Granted, I don't think I run as much negative camber in the rear on my e92, so that may account for something. Also, are you comparing high performance tires with other high performance tires? Comparing them against all-seasons isnt a good comparison IMO.

OK the rubber type is has to consider (summer tire, tire any season, tire high-performance)....

But the MICHELIN DIAMARIS in 19 " which equipped my E53 are classified in the high-performance tires quite as Dunlop Sport Maxx or Bridgestone HP Dueler which equiped E70...

Wow! Your reported distance on each set of tires is low! I have a 2005 X5 4.4i non-sport and I just replaced my first set of Michelins at 52,000 miles. That's a whole bunch of kilometers!

Your e53 4.4 non-sport tires (18" Michelin) are going to last a lot longer than a lower profile bigger tire + softer compound of the 20s. I have an e53 3.0 sport which is the same tire and size as yours and yes I got like 57K miles out of mine.
