On the job Punctured dream: JOHN MILES IS YET TO BE CONVINCED THAT RUN FLATS REALLY ARE THE FUTURE

摘要

For some time, the tire industry has promised that with new technology and materials, runflat tires will no longer suffer the ride and handling deficiencies that have cursed the concept. Perhaps it was the expectation of this promise and the hope that other manufacturers would follow its lead that prompted BMW to accept the challenge of making these weighty and stiff-sidewalled tires work on their normal model range. Having often experienced the negative influence of runflats on vehicle dynamics, I admire BMW for committing so wholeheartedly to the concept, especially as I was reminded yet again of their deficiencies during a recent chassis development exercise using our managing director's 2004 BMW 5 Series.
