The condition of your tires can affect everything from how your Buick operates on the road to its gas mileage and more. Many factors – including time in use, temperature, loading conditions and improper inflation – can affect how fast a tire ages.

The TPMS works by sending a signal from the pressure sensor, located in your vehicle’s wheel, to the instrument control panel, which alerts you when the tire pressure is low. It is recommended that a trained professional inspect, and, if necessary, service your TPMS to determine if it is working properly.

If your vehicle is not equipped with a Tire Pressure Monitoring System (TPMS), check your tires at least once a month with a tire pressure gauge (your vehicle’s recommended tire pressure number likely can be found on a sticker inside the driver’s door). 

Place a penny upside down in between the most severely worn part of the tire’s tread groove. If the tread doesn’t touch the top of Lincoln’s head, it’s time to replace your tires. Also, tread wear indicators will appear when the tires only have 2/32 inch or less of tread remaining which indicates replacement. And if a tire or sidewall is split, bulging, cracked, or has tire cord fabric showing, it’s time for replacement.

To help equalize wear, tires typically should be rotated every 7,500 miles.

If you notice any of the following, it may be time for a tire or alignment service: wheel bends or dents, recurring loss of tire pressure, bumps in the tire sidewalls, vibration emanating from the wheels, or unusual front-end movement when driving on flat surfaces.
