Set of (4) wheels. All four wheels have some degree of flat spotting/bends. I drove on them for over a year, and they hold air just fine and there is only a slight wobble/shake in the steering wheel. There are the usual marks, chips, nicks, etc associated with used wheels. Overall they look decent. They would make a good set of winter wheels, or you could refurbish them (straighten/true & respray) to like new condition.
Staggered setup:
(2) Front 18x8 et 34
(2) Rear 18x8.5 et 37
Lug pattern is 5x120
No TPMS sensors.
Does include BMW center caps.
