Vehicle owners were recently updated on the recommendation from manufacturers to replace tires, even unused
tires, after six years, regardless of tread wear. Research has determined tires degrade over a period of time due to factors like weather, storage
conditions, and type of use. Heiser wants to remind
motorists that by keeping a vigilant eye on the condition of their tires, they can help ensure safety on
the roads and better performance from their vehicle.
Heat or frequent high load conditions can accelerate a tire’s aging process. Signs of aging include
cracking of the tread and sidewall rubber. As not all signs of tire aging are visible, we recommend all
tires, including an unused spare, be replaced after six years regardless of wear due to the possible
effects of aging.
Heiser recommends vehicle owners also inspect the tread of their tires for uneven or excessive wear at
least once a month. Built-in tread wear indicators, also known as wear bars, appear on the tire when the
tread reaches one-sixteenth of an inch, or 2 millimeters. (Wear bars look like narrow strips of smooth
rubber across the tread grooves). A tire should be replaced if its tread is worn down to one-sixteenth of an
When inspecting their vehicle tires, motorists are reminded to:
1. Check the last four digits of the U.S. Department of Transportation (DOT) Tire Identification
Number, located on the tire sidewall, to determine the week and year it was manufactured. The
last two digits show the year the tire was made. (Watch for DOT Tire Identification Numbers that end in three digits. Those tires were
manufactured prior to 2000 and need to be replaced!)
2. Check for signs of aging, such as cracks on the tread and sidewall, as well as any deformation to
a tire’s exterior. Remove objects – such as stones, nails or glass – that can become wedged in the tread grooves.
3. Check valve stems for holes, cracks or cuts that can cause air leakage.
4. Check sidewalls for cracks, cuts, bruises, bulges or excessive wear; if internal damage to a tire is
suspected, the tire should be removed and inspected for potential replacement.
A motorist’s driving can have an impact on tire wear and safety. Hitting potholes and curbs can result in
tire damage and changes in a vehicle’s alignment. If a vehicle seems to pull to one side while driving, this
could indicate the wheels are out of alignment – resulting in uneven and rapid tire tread wear. Heiser recommends vehicle owners:
-Observe posted speed limits, avoid potholes and objects in the road, and take care when parking
not to run over curbs or allow tires to come in contact with a curb.
-Periodically have tires balanced to avoid uneven wear, and seek assistance from the dealership to check for and correct any wheel misalignment or other mechanical problem if tires do
show uneven wear.
-Rotate tires at the recommended intervals indicated in the scheduled maintenance section of the
owner’s manual. This helps tires wear more evenly and will lead to better performance. After
rotating, Heiser can check tire inflation pressures to adjust to the level indicated
on the safety compliance certification label (found on the driver’s-side door
