1 pair K-33 (fits front OEM 19inch tire sizes) and 1 pair K-34 (fits rear 19 inch OEM tire sizes) for 19" OEM M3 tires (245/35, 265/35). Info at:
Just bought a Range Rover and no longer need these. They have been used twice on winter trips to Tahoe, but are in perfect working condition. Set is complete including carrying bags, chains, tools, and instructions. Super easy install as per video above.
$400 shipped for all 4, or pickup in the bay area.
Thanks for looking!
