I drive a 2006 Pontiac g6 GTP and I was broken between these or getting the Pirelli P Zero plus 3s that were already on my car when I bought it from the dealer. Upon installation of these tires I recognized the side-wall was tough just like the P Zeros which makes them a little loud over bumps but I'd take the hard side wall to have the extra stability when cornering fast than having the softer side wall to sacrifice the stability for less noise on bumps on the roads it doesn't bother me. These tires don't have as long of manufacture warranty but I've ran these over 50,000 miles now and there's very little tread difference I expect them to outlast the 70,000 mile interval the P Zeros have which those were down to indicators 500 miles after the 70,000 warranty with rotations done at 15,000 miles when the continentals I've done only 2 tire rotations. Really great tires especially for the money.
