Hey, I was driving back from Durban and had the following happen to me just past Villiers on the N3.
I got a warning light about tyre pressure. I pulled over and checked the 4 tires r18 255/55. They all appeared fine at the time, and been the side of the highway. I reset the warning and headed for a garage.
About 15mins later @ ~100km/hr, I heard a tyre noise so pulled over to discover the rear left tyre had worn to the canvas, presumably I've been running on the run flat tire since the tyre warning. I decided to replace with the OEM spare supplied with the car.
Less then 5km @ 60km/hr my rear disk completely exploded which caused me to immediately pull over. The disk was completely in flames and bits of brake disk fell into the veld beside the highway and started small fires. We used the small amount of drinking water to put the flames around the disc out, and proceeded to stomp out the veld fires started by bits of molten disk. I then sat on the side of the motorway for 3 hours waiting for BMW to come tow the vehicle. It's still under Motorplan (not that helps much).
BMW South Africa have come back saying this was caused by the cars stability control and tire size differential caused by the spare wheel. The cars currently sitting at Boksburg, been "investigated".
I've a couple photos of what the brake disk looked like and parts of the brake disc we recovered. Unfortunately didn't get the camera out in time to catch the fire.

Glad you're ok bud. I see why it's a good thing our spare wheel still has the sticker on it.
