Green Trucking Tip

Correct Alignment

Correct Wheel alignment saves fuel

Wrong vehicle alignment may drastically influence rolling resistance and consequently fuel consumption.

If any of the wheels on a 12-wheel tractor and trailer are not properly aligned, the total drag on the vehicle increases. There is greater “scrub” of the tyres against the road surface and potentially, greater aerodynamic drag when the tractor and trailer are not tracking parallel to the direction of travel.

The example depicted here of a 3-axle trailer shows that correct vehicle alignment helps to optimise fuel economy. In addition, proper alignment prevents poor handling and excessive, uneven tyre wear and extends the life span of the tyre tread.
