GREENSBORO, N.C. -- There is nothing like slipping and sliding on icy roads to make you take a good, long look at your tires.

Ice is difficult to maneuver on with any kind of tire, but the better condition of your tires, the better chance you have of staying safe on slippery roads.

"We had a lot of people coming in, saying 'I just fishtailed. I need to come in, do you have anything today?'" said Mbie Carroll with Casey's Automotive in Greensboro.

Grant Swaim teaches automotive classes at GTCC. He says there are two things drivers must know about before the next batch of bad weather: air pressure in their tires and tread on the tires.

"It's a common mistake about how much air pressure to put in the tires. People need to go by what's noted on the tire placard in the car, on the door or in the owner's manual, and not what is recommended on the tire. The recommended amount on the tire is often too much, which can then lead to even less traction," Swaim said.

To determine if you have tread on your tires, do the penny trick.

"The space between the top of Lincoln's head and the edge of the penny is 3/32nd of an inch. That's the bottom level of acceptable tread on your tires. So if you put the penny into the tread on your tire and you see any of Lincoln's head, then you need to get a new tire," Swaim said.
