IMHO there is nothing wrong with low profile tyres fitted to modern cars allowing better response of car to road, with suspension system of manufacturers choice to compliment plus sound insulation to limit road noise. The undoubtable benefits in improved handling can then be enjoyed without compromise. Sorry to mention our Mini Clubman again but it's the quietest and by far the best handling car we've ever driven with a welcome trait of reducing understeer as you accelerate out of a corner. I suspect some of this may be down to the 17 inch wheel and 225 tyre option we inherited with car though. Concrete road surfaces, thankfully slowly being replaced, do intrude but ironically that's because sound insulation and suspension design otherwise makes the car so quiet. For this reason I've stayed away from run flat replacements when given the choice.
I can fully understand others concern over low profile tyres but their arguments stand mainly for Morgan's and particularly trads I suspect.
