Have a set of 20x10 & 20x10.5 TSW Portier GM 5x120 that was on my 2010 X6.
The Portier employs an innovative multi-piece manufacturing process. Multi-piece wheels combine the light weight of a forged outer barrel with the design flexibility of a cast hub and spoke system. The two components are joined with fusion welding for a near-invisible seam and ultimate durability.
Used them less than half a season so 9.8/10 condition if not perfect.. lots of tread on the tires..
Tire Dimensions:
275-40-20 Falken FK453 106Y
315-35-20 Falken FK453 110Y
They are in storage in my condo locker so viewing will be done there.
Traded my X6 for an E92 M3. Local sale only!
