In owners' own words
Verbatim excerpts from complaints filed with NHTSA about Sailun. Reports are published by NHTSA as filed and are lightly cleaned here only to remove intake codes.
The VIN is from my tow vehicle, your system wouldn't take the VIN of my Fifth Wheel RV (4YDF37329J4700954) which the tire that failed is installed on. The tire in question was purchased in April of 2021 and had approximately 500 miles on it when the tread separated from the tire and became wrapped around the axle of the RV. The tire is a Sailun S637 ST235/80R16.
Was starting out on my 940 mile road trip and 3 hrs into the trip both rear tires lost there tread. I have TPMS and neither tire was out of temp range nor psi range. This is on a dual axle 5th wheel RV. Took 5 hrs for roadside service to respond with acceptable tires. On day two with only 1.5 hrs left, the front two tires did the same thing. All 4 tires have date code of 2320. All 4 tires did lost thread in the same location. All four tires held pressure which allowed me to safely pull off the side of the road both times.
The contact owns a 2023 Subaru Impreza equipped with Sailun Tires, Tire Line: Black Hawk Street UHP, Tire Size: 225/40R18, DOT Number: (N/A). The contact had purchased the tires from Amazon. The contact stated that while the vehicle was parked, the contact became aware of a bubble on the outside of the rear passenger's side tire in December 2025. The vehicle was taken to Mavis Tire, and the tire was replaced. In addition, the contact recently noticed a bubble on the outside of the front driver's side tire. The manufacturer was made aware of the failure, and a complaint was filed; however, the complaint was denied. The vehicle failure mileage was approximately 48,541, and the tire failure mileage was 7,500.
ST235/80R16 Tread Separation. Tread was found to be absence following a stop for the day. Caused damage to the trailer lights and skirting. We were fortunate to stop before it blew apart as the steel belting was exposed. Tires were installed in DEC of 2020 (Williamsburg Walmart), approx 4000 miles on them at the time of the issue. No warning or other issues prior to the tire (flat etc). Replaced tire and repaired vehicle at my expense. Photo documentation uploaded

Sailun ice blazer WST1: what the numbers tell you
Manufacturer treadwear data for the Ice Blazer WST1 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 Ice Blazer WST1 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 Sailun Ice Blazer WST1 has been part of Sailun's catalog since its introduction, and remains a current-production model.
