Alenza sport A/S

I was traveling at highway speed with five passengers, luggage, and bike rack with five bicycles and without warning the driver's side rear tire sidewall completely blew out. The vehicle fishtailed but I was able to move over to the right emergency lane to change the tire. We did not hit any debris. This was a Bridgestone Alenza A/S Sport 235/65R18 tire that was original equipment with my 2022 Toyota Highlander Hybrid SUV. The tires were inflated to 38 lbs. I called Bridgestone and they told me to take the tire to a Bridgestone dealer in Charlotte, NC. They replaced the tire at no charge. I left the failed tire with them but took photos.

The contact owns a 2020 Toyota Highlander equipped with Bridgestone Tires, Tire line: Alenza Sport, Tire Size: 235/55/R20, DOT Number: 1W28AALA15019. The contact stated that the four tires cracked, due to a discrepancy between the stated weight capacity for the tires and the gross vehicle weight. The contact discovered the failure upon inspection of the vehicle and immediately stopped driving the vehicle. An independent mechanic was notified of the failure. The tire manufacturer was also notified of the failure, and the contact was provided a case number. The vehicle had was not repaired. The tire and vehicle failure mileage were approximately 20,000. The contact stated that their wife drove the vehicle majority of the time on local roads. The contact also expressed fears of the vehicle's tires not being able to support the weight of 7 passengers or being able to tow a boat.

235/50/20 104T MFD: 0223 & 5022 (both on the front) Driven less than 15,000 miles so far. Started having this issue around 10k miles. Will have to swap soon before a major accident occurs due to tire failure and checking almost all the boxes that are below. I have no words to describe and neither does the firestone employee. I am attaching pictures. Chunks of tread are coming off from all around the tire. Inside, outside, 360 degree. In the picture you'll see how much tread there indeed is and see how deep the chunks are. This is a major safety issue. I have 2 other tires same model but from 2024 MFD without issue. Please contact ASAP about this at [XXX]S.C. 552(B)(6)
