3a tires are a brand under the Sentury Tire Group. Below is relevant information about the Sentury Tire Group: 1. Origin of Sentury: The Sentury Group was established in 2002 and is located in Xishui, Shandong Province, known as 'China's First Tire Village' and the largest tire manufacturing base in Shandong. After years of development, the group has built an industrial chain focused on automotive tire production, with cluster development of upstream and downstream products. 2. Sentury's industries: The group is a large enterprise integrating automotive tire production, wheel manufacturing, inner tubes, tire curing bladders, bead wire production, international trade, new product development and research, aircraft disassembly, and film and television industrial park development.
The markings on tires are usually meant to tell you about the tire's performance and specifications. For example, when I change tires myself, I pay attention to the combination of numbers and letters on the sidewall. You mentioned '3a,' which might be a misinterpretation or abbreviation. More commonly, you'll see identifiers like those in the UTQG rating system, such as a treadwear index of 300 followed by a temperature grade of A (e.g., 300A), indicating moderate wear resistance and good temperature performance. But this depends on the specific tire. I suspect you might have seen an incomplete marking. I recommend checking the manual or directly looking at the tire sidewall for clear markings like 195/65R15 91T, which are much easier to understand. Tire details are crucial when driving, so if you're unsure, it's best to have a professional take a look to avoid safety hazards.
