Rear wheel drive trucks, equipped with All Season and/or On-Off road tires may exhibit irregular wear of; the front tires. Small amounts of irregular
wear is considered normal and is not necessarily a result of incorrect alignment. Incorrect alignment (especially toe) may result in premature wear of the
front tires, however agressive cornering may also have a similar effect. Drive axle tires are much less prone to irregular wear, therefore they should not
be considered for comparison of wear to non-drive axle tires.
The rate of irregular wear is also dependent upon the depth of tread. New tires are more prone to irregular wear, so it is essential that tires are rotated at
the proper intervals to normalize the wear.
