235/46 r 18 tires currently have 28,000 miles and I’ve already replaced one tire due to lump on side wall that started developing at 12,000 miles and on other three tires. The tread is chipping and separating from the tire on the same pattern all three tires.
235/45 r18 at 12,000 miles miles. I’ve noticed that the front passenger side had a slight little lump on the side wall as it reached 28,000 that ball that bigger and bigger. Had to replace the tire due to the safety concerns. Noticed that the other three tires are showing other patterns of deformities.
I brought my car into Dyer Kia on March 16, 2025 to replace my rear passenger side tire that had a bubble in it.They finally agreed to replace the tire and after being there for 4 1/2 hours they sent me on my way and I was within 5 miles of home and I did hit a small hole in the road and the tire immediately went flat. This tire was the one that they had just replaced in January on the passenger side front I contacted them again and told them that I was going to go to a tire dealer and put on new tires and send them the bill because now I am afraid to even drive my car. Sending them the bill is probably a moot point but it’s worth a shot. My car is brand new has approximately 1450 miles on it and I’ve already had three flats. I had actually told my sales rep while I was waiting for my tire to be put on that Dyer Kia should actually replace all four of my tires with new tires and not Pirelli’s. And he said that’s never gonna happen.I don’t understand why they would put as they call it a racing performance tire on a street car. I had four new Goodyear tires put on the car and the minute I drove away with a new tires, You could feel a total difference in the ride. I hope nobody dies because of all these defective Pirelli tires 235/45/18
On March 14, 2026 I discovered that my rear passenger tire had a large bubble. Pirelli P Zero All season 235/45/18. I contacted Dyer Kia about replacement and they told me that they could not get me in until Monday, this was Saturday. I was due to be somewhere on Sunday and told them I didn’t want to drive on the doughnut or on the tire with the bubble. They said there’s nothing we can do about it till Monday unless you want to go and purchase a tire and have it put on and we will see if we can reimburse you. That was not an option. Especially they after said we’ll see if we can reimburse. I went to there service department on Monday, March 16, 2026 at 8 AM. I told the service tech that the tire was in the trunk and it had a large bubble in it and it needed to be replaced. This tire had approximately 1400 miles on it. This is the second tire in two months that I have had to have replaced. They told me that I must’ve hit a pothole because that’s what causes sidewall bubbles. I disagree. They finally agreed to replace the tire and after being there for 4 1/2 hours they sent me on my way and I was within 5 miles of home and I did hit a small hole in the road and the tire immediately went flat. This tire was the one that they had just replaced in January on the passenger side front I contacted them again and told them that I was going to go to a tire dealer and put on new tires and send them the bill because now I am afraid to even drive my car.

On 1/12/26 I brought my 2025 Kia K5 to Dyer Kia in Lake Wales, Florida, for a blow out on my right front tire. The tire had 700 miles on it. I have only had the car since October 2025. Car was new. Tire is a Perelli and tire size is 235/45/18. When I got there the service technician told me that I ran over something. I did not. I was on a smooth road, no debris on the road. I had two other people in the car with me and they can verify that there was nothing on the road because we walked the road to see if there was any debris. They replaced it under their pro Care policy, because I had not purchased road hazard. I didn’t purchase that because it came in a package that I couldn’t afford. They did replace the tire and then I had to pay for the tire sensor because they said it was faulty. I don’t think I should’ve had to pay for that but that’s another story.
The stock OE Pirelli PZero 235/45 R18 tire had a sidewall bubble identified after 7200 miles. The tire was originally the front passenger tire, moved to the rear passenger after tire rotation.
Within 1 month of purchasing this vehicle (new), the front passenger tire developed a bubble in the sidewall. We had to argue with the dealership to get it replaced. It had less than 200 miles on it. 7 months later there is a bubble in the sidewall of the front driver side tire. There is less than 9,000 miles on these tires. This is a safety issue and a defect that is not being addressed. We keep being told we must have hit a bump or something to cause this. I have owned many vehicles (more than I can count) and have never had this happen before. It should 100% be recalled or covered under warranty. Pirelli P Zero All Season 235/45R18 18-inch alloy
Tire size: P 235/45 R 18 While I was driving home from work my steering started feeling a little shaky. My commute is 6.5 miles. I thought it felt a little weird about 2-3 miles in and I called my boyfriend to meet me when I got home because I could tell something was off, but my tire pressure was fine. When I was about .5 miles from our home, the shaking became audible and violent so I got scared and pulled off. I called again for help while I was parked and walked around to see if there was anything weird and I could not see anything. About 3-4 minutes later while I was sitting in my car waiting, my tire exploded. It shook my car and was so loud that people ran out of the building I was in front of to see what happened. At this point, I had a tire indicator come up saying something was wrong. When I walked around my car again, I saw in one of my tires the cords came out and split in middle of the tread causing separation, and the tire still had air in it. It also scratched my paint around the tire. When I had help come, we put my spare on and got it home, and we took it to a tire dealer the following morning. They all were shocked at how new the tire was and what happened. Everyone is so glad I was parked when it happened and upon research, this is a common occurrence with this brand and type of tire anywhere with 1000-10000 miles on it. My vehicle is less than 6800 mi and the specialists even said the tire had basically no wear and was faulty. On top of that, Pirelli warranty essentially refused to process anything and the dealer that THEY told us they would work with, Pirelli kept hanging up on them. They would not give me a name, let me speak to a supervisor, or give me a call back number should the call “disconnect” again. The dealer was able to comp the tire through their management, but even then, the issue of the faulty tire remains, and based on what I felt, I don’t want someone to get hurt having this happen to them while their car is in motion.
