TIRES

2 complaints

225/50/18 Tires have less that 2000 miles on them and they are pealing at the treads. Literally whole chunks are falling off the tires…looks like someone has been picking and pulling off pieces of my tires.

Apr 06, 2025

Tires came new with car in 2021. The two front tires are chunking. Back tires appear to be fine. Car is not out of alignment, has never been in an accident, no off roading or parking on gravel surfaces. Took it to a Lexus dealer and service rep. says he's never seen a car like this. I contacted Bridgestone, they say there are no recalls - call reference number is [XXX] . INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

WHEELS

1 complaint

I am filing an urgent safety complaint regarding a defective Bridgestone tire on my 2021 Lexus UX250h, purchased new in 2021. At 32,000 miles, the [front left] tire shows abnormal tread tearing and separation, while the other tires show normal wear. This is not consistent with standard aging and indicates a potential defect and not normal wear. My attempts to Resolve it was following Bridgestone’s warranty process through Lexus and a Bridgestone dealer. Bridgestone dealer inspected the tire and blamed alignment, despite recent alignment and proper rotations done at Discount Tire Center on October 8,2025 and regularly. The wheel alignment did not show any tear. According to Lexus, Bridgestone denied the claim based solely on mileage without addressing abnormal tread separation (pls request Bridgestone response from Lexus). The tire poses serious and immediate safety risk of sudden failure, especially in rain, creating danger of a blowout, loss of control, or vehicle damage. I need to replace the tire immediately for safety. If your office requires inspection, please notify me as soon as possible so I can retain it. Tire info: Bridgestone Turanza EL450 BL 225/50R18 95V
