I bought these tires early this summer, and absolutely love them. They greatly reduced the harshness of my very stiff suspension, while being quieter and having insane levels of grip compared.

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

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.

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

Good for summer/wet weather, but you should NOT use these in the extreme cold winter months we see in the Midwest. The rubber compound in these tires will harden and, potentially, crack.

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

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.

Absolutely the best tires I've ever had. I have pushed them to the limit and can not believe they hold the road like they do. A great road tire as the ride quality is amazing also. You feel the road but no discomfort.

Very god tires for the street and quite good on the track. They tended to overheat at track days and not quite as good as the Michelin Cup 2 for track duty. Excellent comfort, noise and wet grip.

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!!
