Changing tires regularly is just one thing truck owners can do to extend the life of their vehicles and tires. Preventive maintenance as recommended by the manufacturer keeps all warranties intact and reduces the risk of vehicle breakdowns on the road in the middle of nowhere.
Many wheel rotation shop dealers offer service contracts that include regular changes to help customers monitor and adhere to their maintenance schedule. If the vehicle pulls to one side or the other while driving, this may mean that the positive or negative slope may differ from one side of the vehicle to the other.
If the front edges of the wheels are pointing out of each other, this is called a bend. The big toe is measured in parts per inch and is usually set to zero. Connections to the inside or outside can cause considerable tire wear and reduce driving behavior, especially when cornering.
These three basic measurements, when set correctly, will fix any alignment issues. A visual inspection of the tires can determine if automatic alignment is necessary, but sometimes there are few or no physical symptoms other than difficulty driving or unusual behavior. If your vehicle shows signs of misalignment, check your steering and alignment system as soon as possible to avoid driving in such dangerous conditions.
Truck owners must also be careful not to loosen the nuts. Once cut, soft metal can rust and break under excessive stress. To avoid this problem, always screw in the ear nuts by hand and turn them by hand until they are tight before using a wrench or air gun to finish the job.
