For my performance cars I like the Continental Extreme Contact, Nitto 555, and of course the Michelin Pilot and Goodyear F1's (Don't buy these to get tread wear). For my Caddy DTS I wanted smooth comfortable quiet tires with a good tread wear rating. It's a straight line car. After I had these Pirelli's mounted I drove it up the freeway about 15 miles and if I would have closed my eyes I wouldn't have known I was moving. Fantastic cruising shoes. All Pirelli said they'd be. Handling on the highway and around town is pretty darn good too. The tires I replaced were Goodyear LS original factory equipment with 40K on them. Would have bought them to replace but 17 inch aren't made anymore. And they're $400 tires. If you want smooth quiet tires for a touring car you can't go wrong with these Pirelli's.

No tire Noise they ride so smooth! Would definitely recommend them!

This is my second set of Pirelli tires on my optima sx, have been well pleased with both the Cinturato and these new P7 tires. Both have excellent dry traction, great cornering ability, and quiet ride. These P7, being new, feel much tighter to the road than the older Cinturato, I had 52,000 on the Cinturato, with good tread left, but felt the wet traction was slipping. I have not had heavy rain yet to judge wet performance of these P7, but expect satisfactory performance. Overall, these tires provide spirited handling, quiet ride, secure footing, and long life.

Only 3000 miles in, but these tires are remarkable. Very responsive, very stable, and very quiet on my X3. Hopefully they'll hold up to 50k or better with tread life. Fuel efficiency seems better than the stock run flats. Absolutely no complaints. The Simple Tire staff exceeded my purchasing expectations, when compared to the other large scale on-line tire websites. Definitely would recommend to anyone looking for a great tire buying experience.
