How can you say that after years of Pirelli delivering tires not fit for purpose?......The tires that are supplied should also meet highest standard of the pinnacle, save the tire blanket ban and degradation gimmicks for the other series ....
I think you need to take your beefs up with the FIA. Pirelli are just supplying tyres that fulfil the design briefs given to them, ie. that deliberately won't last a full race so there are ideally two pit stops a race, that must be made with environmentally friendly compounds (or at least without some compounds they would like to use), etc. etc. Any tyre supplier would doubtless struggle with that brief, maybe not in the same way as Pirelli because they might take some other design paths, but you can bet they would still struggle and the teams and fans still wouldn't like them. (Not least because Pirelli have the benefit of some years of experience trying to produce what is required.) The problem is not so much with the supplier, but the fact that proper racing tyres (as we all understand them) are not presently on the agenda. Blame 'the show'.
