Myth: Your tires should be inflated to the number listed on each tire's sidewall.
“A single tire make, model, and size can be used on several different types of vehicles of varying weights and requirements,” says McLea. “The number on the sidewall is a max inflation pressure for the tire, not the car.” Instead of looking at the tire, look at the tire information sticker on the driver's door jam, or in your owner's manual. The vehicle manufacturer's recommended tire pressure is optimized for safety, traction, and fuel efficiency in the specific vehicle you are driving.
Myth: It’s ok to drive on winter tires all year long.
Winter tires are not designed to be driven when it’s regularly over 40 degrees outside. In conditions beyond their recommended weather and temperature, winter tires have a longer stopping distance, harder handling, and they wear out faster. You should install winter tires only after the temperature drops below 40 degrees (and stays there), and remove them once the temperature is regularly above 40 degrees. As for studded winter tires, “Many regions actually have date ranges when it is acceptable to drive with studded tires,” says McLea. “Outside these dates it is illegal and drivers can be cited.” This is largely because studded tires damage road surfaces, but they can also make driving on clear roads more dangerous. Studded tires are only effective when the ground is covered with ice, not snow, and they can decrease traction when used on wet or dry roads.
Myth: A car under warranty needs to be serviced at the dealer or the warranty is voided.
While some dealerships may want you to think that you have to get your car fixed there in order to maintain warranty coverage, that’s blatantly false. “Services can be performed at any shop,” says McLea. You are required to do the maintenance indicated in the owner's manual, or you may find your warranty claim denied due to neglecting your vehicle. “Drivers should save all receipts in the instance that there is ever a warranty issue.”
