These are the OEM style 333 2011-2013 M sport wheel on X5 X6 E70, E71 with Continental DWS all season tires.
staggered:
20x40x275 front
20x35x315 rear
Just replaced the wheels on my X5 E70 M Sport and had the original machined refinished and new front tires. The rear are almost new with 9/32 tread.
The DWS tires are probably the best handling, best tread life you can buy for these things if you're looking for an all season.
Should fit X3 and other BMWs with hub adapter.
$2400 or best offer. Located in St Louis, willing to ship at buyer cost.
