First of all , i'm glad you managed to get yourself out of the car and that you're OK. It must have been scary. I was wondering if you got to check the car after the accident for wheel bearing, suspension or rim failure? I know you said possibly a blow out and I can't tell from the pics if the tires are down or not on the passenger side.
I was thinking of getting a similar rim/tire combo but after seeing your pics I may reconsider. I remember a story from another beautiful Black XF owner with 21-22s that also suddenly went off road.
Better luck with the new one.
