Even tire tread isn’t optional — it’s safety, savings, and DOT compliance

Описание: On a Class 8 truck, tires on the same axle must stay within about 2/32 of an inch in tread depth. When that difference is exceeded, the tires no longer roll at the same diameter.
That mismatch forces the axle and differential to constantly compensate, even while driving straight. One tire is trying to turn faster than the other, creating:
• Continuous internal stress on the differential
• Excess heat in the axle assembly
• Premature wear to gears, bearings, and seals
From a safety standpoint, this matters because:
• The truck can pull under braking
• Stability is reduced in wet or emergency conditions
• ABS and traction control may react incorrectly due to uneven wheel speed
Over time, that stress can lead to axle failure, locked differentials, or driveline damage—all of which can cause sudden loss of control or roadside breakdowns.
Bottom line:
More than **2/32" difference isn’t just tire wear — it’s a safety risk and a direct threat to your axle. Keeping tread even keeps the truck stable, predictable, and safe.
