Well seeing as my front Pirellis are still doing ok i bought a used set of P-Zero Rosso's in 285-35-19 for the rears to replace the 275-35-19s that are nearly worn out
these new to me zeros have 6mm of tread left (out of 8mm new) and cost me AU$400.
I hope they fit !

 

well pirelli p zero rosso 285/35/19 fit perfectly on the stock 19s
i had to remove the 15mm spacers i had on or there was a little rub on the fender lip.

looks phat from the back now without the spacers.

 

The 285's on the rear look really nice and the way your car is setup it isn't just for show. Enjoy them while you have them as they won't last long Ha Ha Ha

 

Yeah tell me about it ! the 275 pzeros i had before only lasted 20k kms /12000 miles but they stuck very well. The 285s i got on now are pzero rosso , will see if they last any longer but i doubt it !

 

I have had
285 Goodyear f1 (hated them)
275 gmax (liked, almost 35k miles, rotated them)
285 dws
And atm 285 dws 06.
The dws and dws 06 tires are nice, but can't rotate like I did the Gmax and don't last as long, and the Gmax I think did better in rain.
The continentals and generals are both all season tires.
