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 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.

I have had to buy 3 of these tires during the first year of ownership of my brand new car. They are expensive and nails, pot holes, bumps, etc, pop them very easy and they wear pretty quick from normal driving. I don't go to the track.

At the suggestion of Sipan Tire, I put these on the XKR this time. In a word: Wow. Directional, stick like glue, comfortable and quiet. I was worried that summer rated tires wouldn’t do well in March in Canada. It was all for not.

Had these tires for 20k miles. At about 15k, both front tires had large sections of tread torn off. Good track while they last, but catastrophic failures. Would not let me review tires bought in 2022 - even this this is a part time driven car.

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.

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

Have driven for one season on these tires. Love the way they roll and track true so you aren’t correcting the steering like so many other brands. A little more tire noise than the x-ice tires but excellent handelling.

Had these tires on my Gen6 Camaro 2SS. Handling was stellar, but they were a little louder than I had hoped. The pricing has jumped considerably though.

I drive a performance Tesla. These tires have significantly better wet traction than the already good PSS. road noise is quieter than PSS as well. For sure an epic tire. Nice job.
