Whenever vibrations are felt in the handling or uneven wear of the tires is noticed, it is wise to have the wheel alignment and balance checked.


All tires have wear indicators that become visible when the tread has been reduced to 1.6 mm or 2/3 po thickness. The tire must then be replaced. Another trick for checking tread wear is the “red cent test.” Simply insert a penny in one of the grooves making sure to position the Queen’s crown inside the groove. If you can see the points at the top of the crown, it’s time to change the tire.
