What Causes Inside Tire Wear on a Semi-Truck?

Inside tire wear on a semi-truck can be caused by several different factors, but the most common cause is a misalignment of the front axle or steering components. When an axle or steering component is out of alignment, it causes the tires to pull to one side while driving. This pulling creates excessive wear on the inside edge of the tire, and can greatly reduce tire life if not addressed.

Another common cause of inside tire wear on a semi-truck is incorrect toe-in settings. Toe-in refers to the angle at which the tires are pointing relative to one another when viewed from directly above.

If this angle is too great, it will cause excessive wear on the inside edges of the tires. It’s important to have a qualified technician adjust your toe-in settings periodically, as they can change over time due to normal wear and tear.

Negative camber is another factor that can lead to inside tire wear on a semi-truck. Negative camber refers to when the top of the wheel is leaning outward from its normal position, causing an inward tilt at the bottom of the wheel. This inward tilt will cause increased pressure on the inside edges of the tires, leading to premature wear.

Finally, another possible cause of inside tire wear on a semi-truck is improper inflation levels. If tires are overinflated or underinflated, they will tend to wear more quickly in certain areas than others due to excessive or inadequate pressure in those areas. It’s important for drivers and fleet managers alike to check their tire pressure regularly and adjust as necessary for optimal performance and longevity.

Conclusion:

In conclusion, there are several potential causes for inside tire wear on a semi-truck such as misalignment of front axle or steering components, incorrect toe-in settings, negative camber, and improper inflation levels. It’s important for drivers and fleet managers alike to monitor these factors regularly in order ensure optimal performance and longevity from their truck’s tires.
