Have you changed your tires yet? We hear this question repeatedly every spring and fall. And for good reason. If you haven’t changed your tires yet, it’s time to prepare your vehicle for the colder months ahead.  

The Difference Is Real 

Transitioning from all-season or summer tires to winter tires is not just a matter of preference or saving a few bucks in insurance premiums. Changing your tires has positive, measurable benefits. In fact, your bi-annual tire change is a crucial maintenance routine that supports the performance and safety of your vehicle.  

Winter tires are designed to perform in cold temperatures and when driving on ice and snow. Their specialized rubber compounds retain flexibility in cold conditions, providing enhanced traction and control. However, as the weather warms, these same features become a hindrance. The softer rubber compounds wear out faster in warm temperatures, leading to reduced performance and tire life, increased noise, and poor fuel efficiency. 

As their names indicate, all-season or summer tires are engineered for warmer conditions. In general, quite a lot of engineering and testing goes into tire development. All-season tires include specific rubber compounds and tread designs that provide better grip on both dry and wet roads, improving fuel efficiency and facilitating a smoother ride. By using tires designed for the current environmental conditions, you enhance your vehicle’s performance and extend the life of your tires – which will likely save you money in the long run.  

“All-season” vs. “All-weather” vs. “Summer” Tires 

When it comes to fair-weather tires, you have a few choices: all-season, all-weather, or summer tires. While the specific differences in performance of these options are best left to a dedicated article, you can probably guess which option is best for all-around conditions.  

Summer tires sound like a good choice for summer, designed for dry, warm weather conditions. However, the tire tread design and sticky compounds used in summer tires are not well-suited for rainy weather or transitionary conditions (i.e., snow to wet to dry and vice versa). Summer tires are most often found on sports cars or high-performance vehicles, which are seldom driven in adverse weather conditions.  

Now for the other two options. Generally, all-season tires tend to last longer than all-weather tires, but they don’t perform as well in winter conditions. The opposite is true for all-weather tires, which slot in between winters and all-seasons. Regardless, neither performs as well in cold conditions as dedicated winter tires. For North American continental climates (warm summers and cold winters), it’s ideal to opt for a dedicated set of winter tires, as well as all-season tires for warmer weather. If your budget allows for only one set of tires, the all-weather variety may prove to be the most effective choice.

Tire Rotation: A Crucial Step 

If you’re dusting off last year’s set of winter tires, it’s important to observe tire rotation best practices. This is another critical aspect of maintaining tire performance and safety. Over time, tires can wear unevenly due to differences in weight distribution, driving patterns, roadway effects, and/or damage. Rotating your tires ensures even wear, prolonging tire lifespan and balanced handling. A quick review of your vehicle’s Owner’s Manual will provide the manufacturer’s recommendations and best practices. 

Another simple yet effective practice is to mark your tires (perhaps on the inner rim surface) during every seasonal swap to remind yourself of last year’s configuration. Regular rotation with every seasonal tire swap is recommended to keep your tires in top condition. The manufacturer may have recommendations for an alternate tire rotation schedule, so keep that Owner’s Manual handy. 

Optimal Tread Placement: Rear Versus Front 

An often-overlooked aspect of tire maintenance is the optimal placement of tires with varying tread depths. Many drivers naturally assume that the tires with the most tread should be placed on the front wheels, given that the front of the vehicle is responsible for steering and typically bears more weight. However, this is a misconception. 

Placing the tires with the most tread on the rear axle is crucial for maintaining control and stability, especially in emergency situations. In a scenario where the rear tires lose traction along a curve, the vehicle can experience “oversteer,” which can lead to fishtailing, spinning, and travel into oncoming lanes. Having the most tread on the rear tires helps prevent such occurrences, ensuring safer handling and reducing the risk of accidents. In a perfect world, of course, all four tires will have equal tread depth, ensuring traction is equally balanced.

Summary 

Switching from winter to all-season or summer tires and vice versa is not merely a benign seasonal ritual; it’s a vital practice that enhances your vehicle’s performance, safety, and efficiency. By making the change each season, you preserve the integrity of your tires, enjoy improved handling and fuel efficiency, and contribute to safer driving conditions for all.
