What do the three T indices on tires represent?

[MacNatalie]

Tire 3T indices refer to treadwear index, traction index, and temperature index. Below is relevant information about tires: 1. Functions of tires: Mainly include dry traction, hydroplaning resistance, providing comfort, reducing driving noise, impact resistance, wet traction, load capacity, handling performance, average wear, and mileage. 2. Tire cross-section structure: Can be broadly divided into 4 parts: tread, shoulder, sidewall, and bead. Each part has its own function. The tread primarily contacts the ground, the shoulder and sidewall provide support, and the bead contacts the wheel rim to create a seal. 3. Internal composition of tires: Consists of multiple layers of different materials stacked together, including tread pattern, cap ply, steel belt, stress absorption rubber strip, carcass ply, and inner liner.
