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

Great tires that are able to transfer >650hp to the pavement well, are very responsive in corners, quiet, and they have an outstanding mileage warranty! I highly recommend these summer tires!!

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

Had 4s's for a little over a week now, hands down out perform all tiers I had to date. Theyou are better in cold temps by far than Pirelli p zero...Haven't listened for noise just yet.. Maserati

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.

Replaced the Dunlop run flats that came as OEM and wow what a difference. It's like I bought a new car. Much better handling, faster and more responsive. Acceleration is noticeably better and braking is fantastic.

Upgraded from Primacy to Pilot 4S. Changed the entire character of the car. The car was fun as easily tossable on the Primacy tires, but the Pilot 4S tire significantly increased the overall performance. Turn in is particularly awesome.

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

I bought these for track days and they work great on track ,only thing my car weights a little more than the sidewalls can handle, the grip wet and dry is awesome ,I graduated them to street duty and the comfort is extrodenary

exceeded the performance I expected from an all season tire. I took the chance of leaving run flats and have not been disappointed yet HIGHLY RECOMMEND and am looking forward to upgrading to cup 2's
