What is the appropriate treadwear index for tires?

[ReidDella]

Treadwear index between 280 and 320 is appropriate. Treadwear index: The higher the value, the more wear-resistant the tire is, but this only applies to tires of the same brand. Between different brands, even with the same treadwear index, wear resistance may vary depending on each manufacturer's testing standards. Moreover, a higher treadwear index is not always better, as it may compromise other performance aspects such as comfort and handling. Performance parameters: Performance parameters, also known as the 3T indices, refer to treadwear index, traction index, and temperature index. For example: TREADWEAR 220 indicates a treadwear index of 220. Generally, a treadwear index between 280-320 is considered moderate, with higher numbers indicating greater wear resistance.
