Tyre wear and high fuel consumption are well known problems among truck and bus owners around the world.A major cause of this is misalignment of wheels and axlesVarious test have shown that properly aligned vehicles can save up to 8% on fuel consumption and more than 30% on the lifetime of tyres. Apart from the savings, a proper aligned vehicle contributes to a better driving comfort, safer traffic conditions and a better environment.
Why do Wheel Alignment on Heavy Duty Vehicles?
Tests performed by Volvo Truck Corporation in Göteborg shows that by having your truck rig set with the optimal wheel and axle alignment and the correct tyre pressure you can save as much as 15% on fuel cost.
TRUCK WHEEL ALIGNMENT
Did you know that 80% of the tyrewear on the front tyres is caused by misalignment of the rear axles of the truck or trailer? In order to save maximum on fuel and tyres it is recommendable to have the complete vehicle checked 6 monthly for wheel alignment.In above figure 2 all axles of the trailer are rolling parallel with each other but not in line with the centerline of the vehicle. In this case the rolling resistance increases because of the increase of width of the total vehicle. This small misalignment will increase the fuel consumption with 2-3%. In figure 3 all three axles of the trailer are not rolling parallel with each other. In thisparticular case the fuel consumption can increase with at least 15%.
