What the hell happened? 
Did you have to replace the wheel etc...?
somehow the tire split in the middle, and fucking popped off the rim as i was on the highway, the force/momentum from the tire was going faster than me, i was doing 65 (speed limit) the tire was bouncing on the highway right next to the car. time stood still for sure.
i was in an accident in 2015 (head on car crash) same shit happened, time stood still when i got jacked
the car dropped to the ground on the rim, sparks everywhere, lost control, eventually pulled over on the shoulder, the rim was fucked, the front spoiler was fucked (didnt replace that) but the wheel was totally ruined.
it was totally random act of shit luck. I was like 23 at the time working at this finance company and i was a newbie, i was so scared to not show up to work, i just had a trucker get the car to the dealer, then i got a cab to work and dealt the car later on. i remember walking to the next highway on ramp all messed up,
that m3 was my favorite all around car ive ever owned. so much fun. my favorite ever car experience took place in my e46 m3 at a stop light next to a mini van.
