Tire Safety: Old vs. Worn

While a tire’s date of manufacture has a significant impact on its safety (as discussed in our blog post How Old are Your “New” Tires?), tread depth and wear play a huge role as well. It’s important to be aware of how much tread is really left on your tires. Keep in mind that in minimally wet road conditions, a tire worn to 4/32” tread will take about 90 FEET longer to panic stop at 70 MPG versus a new (10/32”) tire.

This is because on a worn tire, the grooves are not deep enough to propel water out from beneath the tread and make proper contact with the road. Known as hydroplaning, the tread skims above the wet surface and the driver starts to lose control of the vehicle.

The info-graphic below illustrates what can happen if you drive on wet roads with worn out tires.

Be sure to check your tire’s tread at least once a month when you check the air pressure. First look for any obvious visible flaws such as cracks, sidewall bulges or cuts. If any of these are present, that tire should be replaced immediately. If you are looking to evaluate tire wear, use a tread-depth gauge (you can find these at an auto parts store, and they generally cost less than $10). Place the gauge into the groves on all 4 tires to determine how much usable tread remains.

Don’t compromise your safety or the safety of others. Be sure to have your tires inspected by a service professional on a regular basis, and to check your tire’s pressure and condition once a month.
