In owners' own words
Verbatim excerpts from complaints filed with NHTSA about Bridgestone Alenza AS Ultra. Reports are published by NHTSA as filed and are lightly cleaned here only to remove intake codes.
I have purchased a set of Bridgestone Alenza AS Ultra (P 235 / 55 R 19 105 W XL front, P 255 / 50 R 19 107 W XL back) in August 2022 for my 2021 Volkswagen ID.4 Pro S RWD EV. After only 12,000 miles, tire dry rot started showing up in June 2023 on all tires. The tires have a 80,000 miles warranty so I don't know how come they started to dry rot only after 12,000 miles. If the tires fail while driving, this can be a severe safety hazard as the vehicle may lose control shall the tires fail.
Brand new set of tires. Less than 100 miles on them. During a left turn at roughly 15-25 mph the entire tire separated from the rim on the rear passenger wheel. The tire is in a secure location and can be inspected if needed. This led to an accident. There were no warning indicators such as low pressure indicators. The low pressure indicator came on after the tire came off the rim. The car went from make a 90 degree turn to making a 45 degree turn and cause my SUV to smash into a house. Tire size was 285/45/R22.
235/55R19 Both front tires are showing abnormal rubber chunking or flaking off on the inner and outer tread. To avoid a possible failure or blow out, I replaced the tires with another brand and model. Bridgestone will not honor their warranty on these tires and I feel they are at fault. Online reports of blow-outs are fairly common with these tires.
Complaints are voluntarily submitted to the NHTSA Office of Defects Investigation and are not verified by NHTSA; they represent owner-reported problems, not proven defects. Counts can be useful as a relative quality signal across comparable tires or vehicles.

Bridgestone alenza AS ultra: what the numbers tell you
Manufacturer treadwear data for the Alenza AS Ultra is not publicly listed. This is common for OEM-only or track-day tires that don't carry a US treadwear warranty. No mileage warranty is published for this tire, which is typical for performance summer and track-day rubber where the manufacturer doesn't make wear-life claims.
Cabin noise data for this tire is not published by the manufacturer. As a general tire built for the passenger segment, the Alenza AS Ultra is positioned against direct rivals within the same category. Comparing it to a tire in a different category (e.g. summer vs all-season) makes the spec sheet misleading because the design targets are not the same.
The Bridgestone Alenza AS Ultra has been part of Bridgestone's catalog since its introduction, and remains a current-production model.
