Here at Stettler Dodge, we know that tires are one of the most important things when it comes to your vehicle. Here are some answers to some frequently asked questions about tires. If you think it's time to get new tires for your vehicle, do not hesitate to contact us!

What Causes Tire Wear?

There are many factors that can cause tire wear, such as your driving style or maintenance habits. Tire replacement is absolutely needed when the tread wear indicators appear. Built-in tread wear indicators look like narrow strips of smooth rubber across the tread and become visible as the tire surface wears.

What Do the Sidewall Markings on a Tire Mean?

How Do I Measure Tread Depth?

A quick and easy way to check tread depth is with a tread-depth gauge - these come in either digital or mechanical versions. If you don't have one, you can simply use a toonie. Put the outside edge of the toonie in your tire's tread.

1. If the tread reaches the bear's paws, your tires are probably pretty new.
2. If it reaches all the way across the silver, they're about 50% worn.
3. If your tire tread reaches only about half-way into the letters, it's time to shop for new tires.

When Should I Replace My Tires?


Tread wear indicators appear when the tires only have 2/32" or less of tread remaining. Rubber in tires ages over time. Other warning signs include:


  • You can see three or more tread wear indicators around the tire.
  • The tire cord or fabric is showing through the rubber.
  • The tire tread or sidewall is cracked, cut, or snagged deep enough to show cord or fabric.
  • The tire has a bulge or a split.
  • The tire has a puncture, cut, or other damage that can't be repaired correctly.

Why Should I Rotate My Tires?


Tires are rotated to achieve a uniform wear on all the tires. Each tire performs different tasks (such as steering in front vs. rear-wheel drive), therefore tires wear at different rates. Tires should be rotated every 8,000-12,000 kilometers, or every other oil change.It's important to rotate your tires according to the correct tire-rotation pattern. Doing this will prolong the life of your tires.


Why Should I Get Winter Tires?


There are a few advantages to getting winter tires such as:


  • The rubber in winter tires is designed to stay more flexible in temperatures below 7 degrees Celsius, which provides better traction.
  • The superior tread pattern in on winter tires can help when driving on snow and ice.
  • Changing your tires seasonally extends the life of your all-season or summer tires.
  • Winter tires have 2-3 times the number of sipes than all-season tires, providing hundreds of more edges for better traction.
