Without the excitement generated by the tyres these last few seasons the sport would have been as boring as during the Schumacher days (and I say that as a Ferrari supporter). Vettel was able to run away at the front but we still got exciting racing further down the grid. I think the tyres unfairly penalise some drivers (because their driving style doesn't suit them) but you can't deny they've made races that could have been incredibly boring more exciting. Not to mention the fact that because we've taken away refuelling, if the tyres were made as good as they could be, pit-stops and strategy would pretty much be taken out of the sport.
