are you remapped ?
seems a little excessive tbh
centre bald could indicate over inflated
(sometimes ! but not always, I know tyres on my old car wore this way and they were def the correct pressures. They were much wider tyres though.)
worth a geometry check too , but if I owned I pirelli Im not sure Id be bothered about keeping that make, just getting the best tyres would sway me.
So id also look at Michelin Pilot Sport PS2 's
Let us know what you decide
