Tire Inspection: Hankook Tire Gauge Index

As We Hit The Road Again, Are Aging Tires Up To The Trip?

Automated tire inspection technology builds trust without adding time to the check-in process.

Over the 2020 Christmas holidays, AAA had estimated that around 84.5 million Americans planned to travel. Although those figures were down nearly 20% from the previous year, it demonstrates the continued affinity for travel, especially in the midst of a pandemic. The Hankook Tire Gauge Index reports that nearly three-quarters of those travelers planned to forego the flight, opting instead to reach their destination by car.

There’s an inherent risk for road trippers, however, that often makes it less safe to drive than to fly for travel. National Highway Traffic Safety Administration (NHTSA) research found that of the 11,500 passenger vehicles they inspected, almost half had at least one tire with only 50 percent tread remaining. An additional 10% had at least one tire that was bald.

While half tread may not seem all that bad, knowing that one in every ten vehicles has a bald tire should be disconcerting. These drivers could be operating a vehicle that could fail or cause them to lose control in slippery conditions. It’s a danger to not only the driver and their occupants, but to other motorists and bystanders as well.

It’s an identifiable threat that many shops pay attention to – but what about tires that are expired?

Expired Tires Are The Unseen Enemy

Virtually no car owner is aware that their tires have an expiration date. Many service shop and dealership staff don’t know about expiration dates either and knowing how to locate the date and read it is even more rare.

Tire manufacturers stamp date codes on tires because their expected life is just six years. The tire code contains four digits that indicate the week and the year the tire was manufactured. When that date rolls around years later, tires are due to be replaced no matter how much tread remains.

But with no one to let drivers know the time is up on their tires, and with car owners unaware that their tires could be dangerous, these expired tires add to the sobering statistics: in 2017, 738 road deaths occurred due to tire failures.

What To Expect From Expired Tires

Expired tires can’t be that bad… can they? The truth is that a tire can only be expected to maintain its integrity for six years, adjusted down from ten years more than a decade ago. When a tire reaches its date of expiration, the potential for safety-related problems increases. Those issues can include:

  • Hardening of the tread blocks, often with the edges showing signs of crumbling
  • Cracks between the tread that widen with time, sometimes deep enough to expose the steel belts
  • Rubber separating from the sidewall or at the shoulder
  • Dry-rot cracking on the sidewall
  • A sudden bulge in the sidewall from the liner delaminating
  • An out-of-round tire from belts that have slipped

With the structural integrity compromised due to age, a tire that looks perfectly fine could actually be the point of failure that cause an accident from a blowout.

Why aren’t service personnel checking tire expiration?

Unfortunately, some service facilities either aren’t advising car owners about expired tires or the message isn’t getting through. It can be for a variety of reasons, namely trust and time.

A service walkaround is a time-consuming process that service advisors often struggle to fit into vehicle check-ins. When it happens, tire tread depth and wear are inspected but the expiry is almost never checked. It comes down to a lack of time, especially during the bustling morning rush.

And despite the research-based data surrounding tire expiration dates, it often comes down to a lack of trust in the service drive. Should a service advisor indicate that a car needs new tires because they’re expired, it’s easy for customers to decline as an “upsell,” not a required service.

Over the past year, many cars sat idle as work from home mandates and travel restrictions reduced mileage numbers across the country. Customers may believe that one of the benefits of this “hibernation” was extended life for their tires. In fact, the exact opposite may be true.

How do you communicate authoritatively to car owners that expired tires are a true concern that puts safety in peril? Automated tire inspection technology offers the solution in a way that builds trust without adding time to the check-in process.

The Winter Tire Opportunity – Now Is The Time

Winters tires aren’t just a luxury, it’s your job to tell your customers the positive impact that the tires can give them.

It was a frigid February morning in Chicago last year. The kind of cold that creeps into the depths of your lungs, making it difficult and even a little painful to breathe. The kind of cold that literally takes your breath away. The snow was falling as I stepped into my car and took off across The Chicago Skyway with the city lights in my rear view. It was around Gary, Indiana, that the lake effect snow engulfed Interstate 90 and made it impossible to see the road more than about 15 feet ahead as I made an unwise attempt to pass a massive snowplow in the right lane. And, it was this moment that I understood the difference between an all-season tire and a true winter tire. My life as a “tire guy” would never be the same again.
