Had these on my 318is last winter, no issues with them at all. They have been sitting in bags outside for this whole summer and they are still holding air.
Rims: 17" x 8" wide offset is ET38
Tires: 225/45 R17 KUMHO I'ZENWIS KW19 (two have about 60% tread and the other two have about 40% tread)

All wheels have curb rash from previous owner, tires are non-runflat, never been patched and no buldges, evenly worn. Will fit OEM Center caps but they are not included.
