In owners' own words
Verbatim excerpts from complaints filed with NHTSA about Nankang. Reports are published by NHTSA as filed and are lightly cleaned here only to remove intake codes.
There was a pencil mark on the inside tire wall where there was a leak. On the test drive there was a light on the dash indicating low pressure. Prior to pick up I was told it was repaired. On -27-23 I was driving the car and was lusting towards the center of the road after I regained control I had the tire checked at a tire shop and found that a patch had been put on the inside of the tire on the sidewall. The problem was reported to BBB and the dealer has not responded. I am in possession of the tire. No one has inspected the tire.

Nankang NS-25 A/S UHP: what the numbers tell you
Manufacturer treadwear data for the NS-25 A/S UHP 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 all-season tire built for the truck-suv segment, the NS-25 A/S UHP 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.
