305 vs 325?
I am looking for new rear tires (3??/25/21)
From my searching, everyone seems to be in agreement that that Michelin Pilot Super Sport are much better tires than the Pirelli P-Zero tires. However, Pirelli makes a 325, where Michelin for the 21" wheel only goes to 305. I have the Michelin now with the 305/25/21, but when it comes time to replace, does anyone have experience which setup was the better one to go with? Thanks. |

Unless you go with wider fronts, I'd stick with 305. 275F/305R are a good balance, or 285F/305R would be even better. Wider rears and not fronts will just create understeer.

Also, the standard rear wheel size is 27.13" (19" 345M, 295/35/19). The alternative wheel size is 26.99" (20" 343M , 295/30/20). For 21" rims, the rear wheel size is 27" (305/25/21) and 27.4" (325/25/21).

Maybe the tires won't bead properly on the rim? Not sure, but I wouldn't recommend it, especially on a 550-hp car. |

I just got an email from tirerack, 305mm is the max they are confident with on a 20x10 rear M5 rim. For more grip on the street and track they recommend the Michelin sport cup 2. Hope this helps....
