Just a side note on this discussion.
A mate of mine ran summer/winter tyres on his Audi RS4. He's a data minded individual and, for reasons best known to him, keeps track of tyre wear on his car and sticks it in a spreadsheet. So, he basically knows exactly the rate of tyre wear per mile over the time he's had the car (several years).
One spring/summer he simply didn't get around to taking the winter tyres off but continued to track the tyre wear. He found that the tyre wear on his winter tyres over summer was identical to the average wear of his summer tyres over the previous few years.
He's a fastidious fellow so contacted Pirreli for comment. Their statement was that they were not surpised since, within the UK (and scotland especially), the temperature rarely gets high enough to make it essential to swap over to summer tyres.
Since then I've run Winter or All Season tyres all year round and never noted any accelerated tyre wear.
Just my thoughts. Your mileage (literally) might vary.
