Washington V. Lincoln: Tread Depth Champion In Greer

Today’s Advantage Auto article focuses on the effect of tire tread depth on braking. When Greer and Lyman drivers talk about stopping power, they tend to focus on their brakes. But our tires are where the rubber meets the road. We have to have tires with enough traction to translate braking power into stopping power. Let’s concentrate on stopping in wet Duncan conditions. In order for a tire to have good contact with the road, it has to move the water out of the way. If it can’t move the water, the tire will actually ride on top of a thin film of water. That’s called hydroplaning and it is a factor in many SC auto accidents. If it’s really bad, you can actually spin out of control. At best, you won’t stop as fast. Your minivan tires have channels for water to flow through. The deeper the channel, the more water it can move. A brand new tire has very deep channels and can easily move a lot of water. As the tire wears down, the channels become shallower and can move less water. When it wears down enough, it can seriously affect your ability to stop on wet SC roads. That’s why it’s so important for Greer and Wellford motorists to replace their tires when they get worn. Consumer Reports and other advocate groups call for a standard of replacing tires when the tread is worn down to 4/32 of an inch. That’s 3.2 millimeters. By comparison, you’ve probably seen the wear indicator that’s molded into tires. When tires are worn to 3/32 of an inch, the tread wear bar is visible. And that little bit of additional tread makes a big difference. Stopping distances are cut dramatically on wet Greer surface streets and Lyman highways. A safe stop from SC freeway speeds with 4/32 of an inch of tread would result in a crash with worn out tires. There’s an easy way to tell when a tire’s worn to 4/32 of an inch. Just insert a quarter into the tread. Put it in upside down. If the tread doesn’t cover George Washington’s hairline, it’s time to replace your tires. With a Canadian quarter, the tread should cover the numbers in the year stamp. You’ve probably heard of this technique using a penny and Abe Lincoln’s head. That measure gives you 2/32 of an inch – half the suggested amount. And if you have uneven tread wear – have us check it out at Advantage Auto.
