DWR Tire & Auto

When talking about stopping power, we tend to focus on our brakes. But our tires are where the rubber meets the road. So having good brakes isn’t enough: we have to have tires with enough traction to translate braking power into stopping power.

Let’s focus on stopping in wet 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.

To move water out of the way so the tire has channels for water to flow through. Look at a tire and you’ll see channels that run around and across the tire. They’re designed to direct water away from the tire so it can contact the road better.

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 roads.

Consumer Reports and other advocate groups think that a good standard of replacing tires when the tread is worn down to four-thirty-seconds of an inch. That’s 3.2 millimeters.

When tires are worn to two-thirty-seconds of an inch, the tread wear bar is visible. So the recommended standard has twice the tread depth as a completely worn out tire – and that little bit of additional tread makes a big difference. Stopping distances are cut dramatically on wet roads. A safe stop from freeway speeds with four-thirty-seconds of an inch of tread could result in a crash with worn out tires.

There’s an easy way to tell when a tire’s worn to four-thirty-seconds 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.

Today’s DWR Tire and Auto article focuses on the effect of tire tread depth on braking. When Crown Point and Crown Point 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 Merrillville 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 IN auto accidents. If it’s really bad, you can actually spin out of control. At best, you won’t stop as fast.

Your family car 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 IN roads.

That’s why it’s so important for Crown Point and Griffith 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 Crown Point surface streets and Crown Point highways. A safe stop from IN 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 DWR Tire and Auto. It could be a problem with your steering or suspension components or a wheel alignment problem.
