Tire Tread/belt Problems of Lexus RX

The tire (bridgestone ecopia 422 plus 235/55r 20 102v m+s) failed within seconds while driving on the highway at 70 mph. Luckily I did not lose control and was able to steer the car from the middle lane to the birm thanks to the semi driver on my right who allowed us to get off the road quickly. There was almost no rubber remaining on the rim and the tire pressure sensor was gone. The tow truck driver and ntb tire technician said the tire appeared to have failed due to delamination of the steel belt. Subsequent searches on the internet seem to support belt failure as the cause of the rapid loss of the tire. Walmart has refunded the cost of the failed tire. Bridestone is being less than helpful relative to the remaining three tires, which have less than 2,000 miles on them.

Tires installed by Lexus on sept 27, 2022 are shredding and coming apart in chunks at 37,000 miles; tire is rated 60,000 miles. This is 56% of the projected life of the tire. Previous tires, same brand and size, only lasted 29,000 miles; 1/2 of the life of the tire. Current tires have good tread depth and life left if the chunks were not uniformly coming off of all tires. This condition leaves the tire vulnerable to road hazards and moderately sharp objects. Failure is clearly imminent. Dealer, upon inspection July 1, 2025, did suggest immediate replacement of the tires at normal retail prices. No warnings or alerts or other symptoms are present. There has been a slight loss of air pressure.
