There are many factors that can cause tire wear on your Cadillac tires, such as your driving style and tire maintenance habits. New tires are 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.

Cadillac Tire Wear: Toe Tire Wear

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.

Cadillac Tire Wear: Cupping Tire Wear

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.


Cadillac Tire Wear: Camber Tire Wear

Camber Tire Wear

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

Cadillac Tire Wear: Edge Tire Wear

Edge Tire Wear

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

Cadillac Tire Wear: Center Tire Wear

Center Tire Wear

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


Digital and Mechanical Tools

A quick and easy way to check your Cadillac tire wear is with a tread
depth gauge. It measures tire tread depth from 0 to 19/32 inch. These
tools come in either digital or mechanical versions.

The Penny Test

The easiest way to check wear on your Cadillac tires is with a penny.
Place a penny upside down in between the tire tread as shown on the
right. If you can see the top of Lincoln’s head, the treads are worn
and tire replacement is needed.

Tread wear indicators appear when the tires only have 2/32 inch or less
of tread remaining. Rubber in tires ages over time. This also applies to
the spare tire (if available), even if it is never used. Multiple factors
including temperatures, loading conditions, and inflation pressure
maintenance affect how fast tires age.

Other warning signs that your vehicle will need tire replacement:

  • 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 split
  • The tire has a puncture, cut, or other damage that can’t be repaired correctly


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. When storing a vehicle for more than a month, remove the tires or raise the vehicle to reduce the weight from the tires.
