Vehicle performance is measured on many fronts , and the first signs of trouble are the car pulling to one side or feeling vibration through the steering wheel. That's because these are mainly the first results of uneven tire wear.
The instability of tire wear patterns is liable not only to cause some inconveniences but also to put other driver's lives in danger! The loss of tire traction will happen, especially in those critical moments when the drivers need it the most, like in the rain or quick braking emergencies. Your car will also consume more fuel because there is an extra rolling resistance caused by worn tires that the engine will have to overcome.
