Passenger Tyre Tread Depth Indicator Check – Tire Test Equipment – Qingdao Coop Tire Technology

To check passenger tire tread from Qingdao Jinghe Tire Technology Co., Ltd., start by inspecting the tread wear indicators—small raised bars in the tread grooves that become level with the tread when wear reaches 2/32 of an inch, signaling the need for replacement. For a precise measurement, use a tread depth gauge: insert the gauge into the deepest part of the tread, ensuring it contacts the base of the grooves, and read the measurement in 32nds of an inch. A tread depth above 4/32 inches is ideal for most conditions, while below 2/32 inches is legally unsafe. Additionally, visually inspect for uneven wear, cuts, or bulges, which may indicate alignment issues or damage requiring professional attention. Regular tread checks help maintain safety and optimize tyre performance.
