WHAT CAUSES TIRE WEAR?

There are many factors that can cause tire wear, such as climate, road surface quality, and your driving style and tire maintenance habits. Tire replacement is absolutely needed when the tread wear indicators appear. A tire’s built-in tread wear indicators look like narrow strips of smooth rubber across the tread and become visible as the tire surface wears. Also, check for the signs of tire wear listed below.

Toe wear suggests a wheel alignment issue and typically produces a feathered wear pattern across both front tires.

TOE TIRE WEAR

Excessive wear on the inner or outer edge of the tire, commonly known as toe wear, suggests a wheel alignment issue. This typically produces a feathered wear pattern across both front tires.

Camber tire wear results from a misalignment that causes uneven wear on one side of a tire.

Camber Tire Wear

Uneven wear on one side of a tire tread may occur when the tire is leaning due to camber misalignment.

Center wear occurs when a tire is overinflated, resulting in the center of the tire wearing more quickly than the edges.

Centre Tire Wear

Centre wear occurs when a tire is overinflated, resulting in the centre of the tire wearing more quickly than the edges.

Cupping wear occurs when suspension/balance may be compromised. A diagonal scalloping pattern on the tire may appear.

Cupping Tire Wear

Cupping wear occurs when a suspension/balance may be worn, bent or somehow compromised. You’ll notice a diagonal scalloping pattern on the tire.

Edge wear occurs when a tire is underinflated, resulting in the edge of the tire wearing more quickly than the center.

Edge Tire Wear

Edge wear occurs when a tire is underinflated, resulting in the edge of the tire wearing quicker than the centre.

MEASURING TREAD DEPTH

Digital and Mechanical Tools

A quick and easy way to check your tire wear is with a tread depth gauge. These tools come in either digital or mechanical versions. When your depth gauge tells you that you’ve reached a depth of 1.5 mm or 1/16 inch, it’s time for new tires.

TIRE WEAR WARNING SIGNS

Tread wear indicators appear when the tires only have 1.5 mm (1/16 inch) or less of tread remaining. Rubber in tires ages over time. This also applies to the spare tire (if equipped), even if it is never used. Multiple factors including temperatures, loading conditions, and inflation pressure maintenance affect how fast tires age.

REPLACING YOUR TIRES

The lifespan of your tires depends on how they are used: average driving speed and weather, as well as the types of roads driven on. The Certified Service experts at your dealership are trained to find the right tires for your vehicle, which are suited to your driving profile. The best way to ensure you get the right tires for your vehicle is by scheduling an appointment.

WHEEL (RIM) REPLACEMENT

Knowing when to change the entire wheel/rim is also a key element of keeping your tires and vehicle in good shape. The replacement wheel should have the same load-carrying capacity, diameter, width and offset, and be mounted the same way as the one it replaces. The trained tire service experts at your dealership know what kind of replacement wheel/rim you need and when you need it.

HOW TO PROPERLY STORE TIRES

Tires age when stored normally mounted on a parked vehicle. Park a vehicle that will be stored for at least a month in a cool, dry, clean area away from direct sunlight to slow aging. The area should be free of grease, gasoline, or other substances that can deteriorate rubber. This also applies to unmounted tires.

Parking for an extended period can cause flat spots on the tires that may result in vibrations while driving. You may also try parking your vehicle on a soft surface or on material like rubber or foam insulation that will have a bit more give and help alleviate flat spots.
