Had new PZero on the C4 GTS I bought and almost immediately, LOUD AS HELL…. Even though I’ve only driven about 150 miles, feel so much better and… QUIETER..!!!

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.

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

After 85 days, this tire took on a flathead bolt. The picture does not make sense. My local tire repair center patched the tire; however, I am alert for further problems.

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.

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

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.

I bought a new Mercedes S class 11/21. Since last Spring i have replaced three of the tires because of chuck holes. They are way too fragile for use in the midwest. I experienced one failure last spring and two others this month.

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
