Best tires I have ever had! My car is currently making close to 700hp and these do pretty good at putting it down. After 10k of spirited driving tires still have over 60% of tread remaining. Only con would be tires are so sticky little rocks get stuck onto them easily.
Came as original equipment. Only got 23,600 miles out of them driving conservatively. Pirelli DOES NOT warranty their OEM tires!? There is supposed to be a 45,000 mile warranty on these tires, but Pirelli offers NO compensation for OEM tires. Figure that out! All four tires at 23,600 miles were at 2/32! Very poor tire and worse customer service from Pirelli!
If you on a MUSTANG, these are great! The Perelli's that come stock are dn good, but I am so glad that a friend of mine that owns his own tire/auto shop sold me on the Extensa HP! super smooth/just right softness/ hold a curve like riding a rail. Not to mention that you will hole shot every Camaro W/GoodYears.
