After exchanging the all season tires to the summer tires, the grip and performance on summer version tires is a big difference. Soo much better. Bravo

On my Porsche 2003 c4s I purchased 4 ea Pilot Sport 4s and the car runs & tracks beautiful also eliminated a lot of the Road noise I had from Previous "FALCON" tires

Great tires for daily or track or they stick well in cornering on dry or wet conditions other than they don't last that long and are not cheap. Good for sports car

Best all-around performance tire, excellent in rain. They do wear quickly but that is understood with sticky compounds.. Hydroplaning resistance reduced quickly with wear, but still the only performance tire I'd trust

Made my Focus RS even a better performer than it already was.. Ready for the next Targa SCCA multi-event. Good for track events, autocrosses, and daily driving. Better than some full race tires I've had in the past.

I have about 1,500 miles on these tires that I bought new. However, on one of the tires are two, approximate 1” vertical bulges protruding outward. Is this normal? Great looking/handling tires, other than the defects.

Excellent traction in dry and wet. In acceleration, braking and cornering. I have no idea how they would be in the snow and I won't be finding out. expect they wouldn't be good. Have snow tires

Switched from Michelin Primacy to the 4s and the ride quality and handling improvement was a nice upgrade. I live in a fairly warm climate with good road surfaces.

While these tires had excellent performance in dry and wet, they were too fragile, i had one go out due manufactuer defect. Then another another one go out from hitting pot hole.

The summer with these tires has been good, however the wear is not as expected. I will probably only get another summer out of these tires. The soft compound wears very quickly in this application.
