What comes std. on the M5?

What offset are the front and rear wheels? The rear wheels are wider than the front, right?

The E39 M5 comes std. with 245/40 - 18' at the front and with 275/35 - 18' at the rear (we're talkin' about 400hp here... and sometimes, believe me, these rubbers r not enough!!).
BMW recommends Michelin or Dunlop (i'm pretty happy with Mich's), but some folks prefer Bridgestone... the problem is, lots of grip, but only for (more or less) 8000 miles... then, buy a new set...
