Actually I had it happen on my old AWD 325 iX. I hit some sharp debris in the road at 75 mph and the next thing I know my whole RR tire is gone. The car handled great with just 3 wheels and I made it very safely to the side of the road with no wheel damage at all, gotta loved forged wheels!

Three Wheelin'
I've blown a tyre on a New Zealand Airforce unimog truck. i was very lucky it was a rear tyre not a steering one as i was doing about 70 kph and I would have gone off the road. i was on my training course to sign out on them.
I also blew a rear tyre on landrover airforce ambulance. I was 10 mins off base on the motorway and had to wait 30 mins for help frm work as they didn't have any tools on board for me to change the wheel. The problem with the ambulance was it never got used more than 10km a week or more than 30kph as thats the speed limit on base. i'm sure the tyres were old but no one cared because from lack of use they had good tread.
i had a wet road excursion in my 932 that i put down to lack of experience transitioning from 70's turbo tech off-boost to on-boost and tyres of undeterminable age. I changed all 4 tyres after that.

Thinking of going with a new set of Sumitomo HTRZ II's or III's...comments/suggestions on these...looking for something on the affordable side that isn't a POS, as I don't want to experience any more tire issues!

rear tire blowouts are always WAY WAY WORSE than front tire blowouts on
any front-engine car, any front engine transaxle car, any SUV, or truck.... ALWAYS...
i'll try my best to explain why...
all modern automobiles have one really cool feature. they love to go straight. and they do this well... even better, is that the laws of physics are on their side, increasing the likelyhood that they will remain going straight even after suffering a blowout of a front tire.... this is in no small part due to the car's moment of intertia..... here, a front-heavy car with 2 good tires in the back and one the remaining good tire left on the front of will work in concert with the car's moment of intertia, and these positive elements will have quite a lot to say about the car's ability to keep going in a relatively straight line.... in addition, the driver will be able to react and adjust the orientation of the front wheels — thus decreasing the negative forces being applied to the front of the car via the blowout.... therefore, a front tire blowout can safely be called a damped harmonic oscillator because of the presence of strong stabiling forces.... THE CAR'S MOMENT OF INERTIA, FRICTION, AND YOU, THE DRIVER....
there is however one huge problem from a front tire blowout.... the constant pull to either the right or left... there are cases where the pull is just too much to overcome... and worse: the moment you leave the road, and you're on dirt, the postive corrective forces that the good front tire can offer, are greatly decreased (second video)....
but, a rear tire blowout is still worse.... when you get a rear tire blowout, the car will begin to fishtail wildly almost immediately and you can lose control very quickly.... thus it can loosely (and quite properly) be called a driven harmonic oscillator....
in the video notice how Casey Mears can barely keep the car going straight... why ?
because he's fighting a driven harmonic oscillator. a killer.

amazing videos.
i'll count myself lucky all i had was the surprise of the noise from the blow out and then coming to a stop at the side of the road for both incidents!
this is similar to the mog
and this is the (very top heavy and horrible to drive carburated rover v8 ) ambulance

It's perfectly suitable for that size wheel. You can also get Dunlop Direzza DZ101 (I think) (non-star spec to save money). I like mine so far....
