Nankang tire failures: owner complaint analysis
What owners told NHTSA about Nankang tires; 30 written complaints across 1 line, classified by failure mode and compared with the whole tire-complaint corpus.
Nankang lines with enough reports to analyze
A line appears here once at least 30 owners have filed a written account of a failure. "Relative" compares the most-described problem on that line with how often it appears across all tire complaints.
| Line | Written reports | Most described | Relative |
|---|---|---|---|
| Mission | 30 | Blowout or sudden deflation | 2.6× |
Across every nankang tire
What owners described
Blowout or sudden deflation appears in 42% of these reports; about 2.1× as often as across all tire complaints. Percentages are shares of the 86 reports filed against Nankang tires across every line and vehicle that include a written account; a single report can describe more than one problem, so they do not total 100%.
| Reported problem | This subject | All tire complaints | Relative |
|---|---|---|---|
| Blowout or sudden deflation | 42% | 20% | 2.1× |
| Tread or belt separation | 28% | 13% | 2.1× |
| Sidewall failure | 26% | 15% | 1.7× |
| Bubble or bulge in the tire | 12% | 6% | 2.0× |
| Cracking or dry rot | 5% | 9% | 0.5× |
| Loss of control, rollover or collision | 5% | 8% | 0.6× |
Mileage at failure

How to read this
Complaints are voluntarily submitted to the NHTSA Office of Defects Investigation and are not verified by NHTSA. They are owner-reported problems, not proven defects, and volume tracks how many of a tire were sold as much as how often it failed. What is comparable is the mix: which problems owners describe here versus across every tire complaint on file. That comparison, the mileage distribution and the mode rankings on this page are our analysis of the public record.
