You should not ignore this common maintenance task, which should be performed every 5,000 to 8,000 miles. You may consider it to be a minor issue, but remember that the only thing that separates your 2-ton vehicle from the road is its tires. When your tires are well maintained, you will be able to travel for tens of thousands of miles without experiencing any problems.
It is possible that tires will not wear evenly if they are not rotated. In front-wheel drive vehicles, the front tires play a greater role in braking, and they wear out more rapidly because they must claw for traction.
