Just saw 5th Gear on TV and they had a great report on blow-outs. Tiff took several regular cars out on a track and he was unable to control the cars at 60mph when either the fron or rear tire blew out.
Then they took a 530i and had him do a lap around the track.
Afterwards they drilled holes in all 4 runflat tires and he took the car around the track again. Although the recommendation is to not exceed 50mph with the tires being flat, he drove it as fast as he could. His top speed was 90-95mph at one point. The car handled just fine and he finished the lap just 15 sec. slower than with the tires normally inflated. No loss of control, to tire coming off the rim. Awsome proof that runflats are worth it.

I don't think the purpose of RF's were ever in doubt! Just the ride quality. So those of you with RF's who is going to carry on regardless with a punctured tyre now we know there is no detrimental effect on the cars handling ability? Why bother shelling out money for a new one when you can drive it flat?

Sometimes I do gripe about the fact that the run flats give the car a harsh ride, but they really do work. A few days ago I was on my way home from the office when my screen lit up to tell me that I have a flat tyre. I pulled off to the side of the road and sure enough there was a nail embedded in one of the tyres. I was on the New York State Thruway and had one exit to go. I drove the bloody car home with no problems, even caught myself going over 60 mph. There was no discernable change in the car's handling that I could detect. So next time I bitch about the harsh ride I will remember that I didnt have to sit on the side of the road in the dark in my suit trying to change a tyre.

I aIso saw the episode. I completely agree that the RF's are great from a safety point of view.
But l still wont use them again until they get the ride quality issues resolved.

Several times a week. Unfortunately we seem to be 1 year behind from the UK broadcast. But still an entertaining show.
