    • Great tire. Look out for bugs in the tire when receiving. Bug the length of my middle finger.
Style: PILOT SPORT A/S 4 Size: 225/45ZR18/XL 95Y
The tires are perfect. I have no issue with them. The issue I have is that when I receive the tire, there was a humongous cockroach in it a.k.a. Palmetto bug. So if you please contact wherever those tires came from and tell them, they need an exterminator in that building or warehouse. I’m just happy that that bug didn’t lay any eggs in my house. I’ve never seen a cockroach that big. I only found out when I took it out of my car at the garage and saw it rolling around in there. I was fortunate that it was so big it couldn’t crawl out of the tire. Please relay the message to the warehouse. Thank you. ... show more

    • No more run flat tires
Style: PILOT SPORT A/S 4 Size: 255/35ZR18/XL 94Y
I got these for my BMW Z4. It came with very loud run flat tires. I was not happy with the run flat traction or ride. These tires are not cheap but it is a whole different driving experience. They are much quieter and I am very happy with the grip and traction. It is a light car, but it does not hydroplane in pouring down rain with these tires. I can't speak to the tread life, but the tires are a well thought out design. I'm impressed. I do recommend these tires without hesitation. ... show more

It's a tire i guess. Only complaint is that it should be more obvious that it's 200 for only one tire, Shouldn't include pics of a set of 4 tires it's misleading.
