  • December is Tire Safety Month! We strive to help educate motorists and our customers on proper tire care and maintenance year-round, but we wanted to highlight tire safety to support this country-wide initiative.

    Our friends over at RMA remind us to Be Tire Smart Play your P-A-R-T!


    Maintaining proper inflation pressure is crucial for getting the most out of your tires, both in long mileage and a comfortable ride. Air pressure is measured in psi (pounds per square inch) and should be adjusted when the tires are “cold”, which means check it early in the morning or after the vehicle has been sitting for at least 3 hours.  If you need to adjust for a “warm” tire, simply add 2-4 psi to the vehicle manufacturer’s recommended cold inflation pressure, and check the cold inflation pressure at your earliest convenience.  Even a perfectly healthy tire loses 1-2 psi per month, so it’s important to check your pressures often.  Get your tire repaired at the first sign of a leak or nailhole puncture.  Remember, running your tires underinflated also means that you are overloading them, which can do permanent damange. Stop by any Sullivan Tire for a complimentary air pressure check and adjustment. Come as often as you like, no appointment necessary!

    Tire Pressure Check - Marshfield


    A bad jolt from hitting a curb or pothole can throw your front end out of alignment and damage your tires if not corrected promptly.  Have your alignment checked at least 1-2 times per year, or at the first sign of the vehicle not tracking straight when driving on a straight stretch of road (a.k.a. “pulling”).  When you purchase our Tire Maintenance and Protection Plan (TMPP), you get a complimentary alignment check every 6 months for the life of the tires! 


    Regularly rotating your tires will help you achieve more uniform wear. Unless your vehicle’s owners manual has a specific recommendation, the guideline for tire rotation is approximately every 5,000-7,000 miles, or roughly every other oil change.  Frequent tire rotations and tire inspections can help to identify an alignment or steering problem before too much damage occurs to the tire. This service is complimentary for the life of the tires when you purchase our Tire Maintenance and Protection Plan (TMPP).


    A tread depth guage is an inexpensive and effective tool for measuring the amount of tread left on your tires.  Hydroplaining can occur even at low speeds if the tread is not deep enough to channel the water from under your tires.  The tread depth measurement is taken in 32nds of an inch, and should be taken from the tread grooves at three different areas of the tread (inner, center, and outside).  If any part of the tread is at or below 2/32″ depth, the Department of Transportation (DOT) considers the tire as having reached the end of it’s useful life and should be replaced.
