Hello, up for sale is a complete set (4) 748M 20" Black Winter Wheel/Tire - 9x20 Part #36-11-2-462-595. Tires are Pirelli Scorpion Winter Runflats.
This includes Wheel, Tire, TPSM, and Center Cap. This is a square set up. This set will fit all current generation X5, X6, X7, X6M and was installed on my X5M until I decide to get a diesel GMC Sierra for Big Bear.
One nice aspect of having 20" and not staggered 21's or larger is that you can still get snow cables for winter conditions where Caltrans or other authorities still require you to install chains regardless of snow tires or AWD.
These were purchased from getbmwparts.com in the beginning of Oct 2020 for my X7 and I can confirm that they will clear X7's with M performance brake option as well as 2021 X5M brakes with no problems.
Drove approx 2000 miles on the tires between the X7 and X5M on them.
Paid $864 per wheel/tire combo x4, so with tax, shipping etc. came out to approx $4000.
Would like to sell local because shipping freight on these would be most likely cost prohibitive. Located in San Diego, will drive to meet folks half way depending on where they are in So Cal. If you are on the way to Big Bear in Orange, Riverside or San Bernardino Counties, then am willing to me you along the way when I go up every week to drop off the set.
FYI: Snow cable model from Peerless (officially called on Amazon): Security Chain Company SZ441 Super Z6, approx $126
