I have owned this vehicle close to three years and these were the all season tires that came with the car.I live in New England where I run snow tires on the car from October to April every year that I have owned the car. The car has 30K miles on it ,but the tires that came with the car only have about 10K or 7/8 tire tread left. The tires have become very noisy and are starting to cup. I did take the car to the dealer and had the front end checked out and nothing is worn or out of alignment. Tires were rotated at 5K intervals .I contacted Dunlop and was told there was not much they would do since the tires were made when Dunlop was owned by Goodyear. Dunlop is now owned by Falken. I was offers 30% off a new set of tires (Dunlop) as a good will gesture. A new set of tires will run about 1K with tax and mounting/balance. I should have to spend that kind of money on tires that are not worn, just poorly made. Falken admitted that they have a lot of complaints about this tire.

The passenger rear tire experienced a catastrophic tread separation failure on the highway at speed limit speed. Since this was on the freeway, loss of control could have been experienced and caused a severe incident injury to drivers in the vicinity of the incident. The problem just happened and will be inspected by an authorized dealer. There were no warnings until the tire of the incident. These tires have been rotated according to schedule and have less than 21,000 miles.

On 10/7/25, the passenger side front tire malfunctioned - I currently have the tire. On 9/7/25, the drivers side rear tire malfunctioned - I no longer have that tire but I have included the receipt for the new tire I had to purchase. On 9/7/25, I was driving alone on the Florida Turnpike at night and in the rain, when the rear drivers side tire blew and was completely destroyed with multiple holes in the sidewall. Fortunately I was able to maintain control of the car, but I was stuck on the side of the highway until a Florida Road Ranger came to assist. The problem was reproduced on the morning of 10/7 when I found my passenger side front tire flat with a split sidewall. I am scheduled to take the car to the Lexus service department on 10/8/25 for inspection. The front passenger tire does not feel like rubber, it can be described as a mix of cardboard and plastic. On the evening of 9/7/25, when the rear drivers side tire blew, there was little warning, the low tire pressure warning light came on and I felt the flat tire in less than one minute. I purchased this new 2025 Lexus GX 550 in March of 2025 from JM Lexus in South Florida and these were the original tires. The car currently has 9,766 miles on it and used for commuting to work and running errands. [XXX] PT5A, 265 /55 R 20.
