Back in 2007, Congress told the

Administration to come up with
new fuel efficiency labels on tires.
Mark Brush reports on when we might
see those labels in tire shops:
It’s been 2 years, and the government is still working out how to get this labeling program going.
Right now, if you walk into a tire shop, it’s hard to compare tires on how fuel efficient they are. There’s no official standard yet.
But that should change soon. The new tire labeling program is expected to roll it out in the next few months.
Dan Zielinski is a spokesman for the Rubber Manufacturers Association. He says they support a labeling law because it’ll help competition.
It could give tire makers something to brag about.
“’It will be an incentive to say ‘my tire is better because,’ or, ‘my range of tires here are better because.’ It offers the consumers better performance on certain criteria. And I think that will drive the market even before the consumer demand does.”
A more fuel efficient tire will only get you a couple of miles per gallon more. But, put those tires on the 200 million cars and trucks driving the roads these days, and that could add up.

Playgrounds are supposed to be
safe places for kids to play.
But Tamara Keith
has the story of a leaked memo
from the Environmental Protection
Agency that indicates there might
be a problem with crumb rubber:
(sound of kids playing)
Shawn Clancy’s two sons are having fun running around a community play set. And if they fall, he says there’s plenty of crumb rubber. It’s made from recycled tires and it should stop them from breaking any bones.
“I’ve seen kids fall from far distances. I’ve seen the give. I’ve seen them get right back up and kids are playing with it. It’s fun to dig in. They can kind of play with it. It’s about 8 inches thick, so there’s quite a bit of it.”
Clancy and his neighbors like the fact that it lasts a long time and that it keeps old tires out of landfills. And they’re not the only ones.
(outdoor sound)
I’m outside of the White House right now, just on the other side of the fence. And somewhere on those grounds, probably behind some tall shrubs, there is a play set. It’s a new play set that Sasha and Malia, the first family got. And underneath that play set is a pretty thick layer of rubber crumb to protect the girls if they fall.
I don’t think anyone is suggesting that this exposure is good for kids. The only question is how bad could it be.
Jeff Ruch heads Public Employees for Environmental Responsibility. His group got its hands on some documents where scientists at the Environmental Protection Agency question whether there’s stuff in the crumb rubber that could be toxic to kids.
“What’s known is very very little. They list, I think it’s 30 toxic chemicals in one of the memos. And so far work has only been done on two of them.”
An EPA spokesman says the agency is doing a preliminary study of 4 playgrounds, looking for lead and volatile organic compounds. The results aren’t in yet.
The Rubber Manufacturers Association says there are more than a hundred studies showing scrap tires are safe in playgrounds and that environmental groups are over hyping the concerns.
Richard Wiles isn’t buying it. He’s senior vice president of the Environmental Working Group. And he feels like he’s seen this movie before – with arsenic treated wooden playground equipment.
“It was a really bad idea to use arsenic in this way and for about 20 years this is what we did.”
And kids all across the country were playing on this contaminated wood. But the thing is, initially arsenic treated wood seemed like a great idea, because it prevented decay – and made play structures safe and strong for years.
Parents might be left with the feeling that you just can’t win. Wiles thinks there’s another lesson.
“The basic problem is, we tend to use these products before we evaluate the health and safety concerns. We tend to just throw it out there without thinking that oh this is a surface that is made out of something that was previously considered hazardous waste.”
With all the alarm about very real arsenic problems, and yet to be verified concerns with crumb rubber, Donna Thompson says it’s easy to forget that playgrounds today are safer than they’ve ever been. She’s executive direction of the National Program for Playground Safety. For now she’s standing by crumb rubber, because it does such a good job of preventing broken bones.
“I’m not going to worry about it yet until I hear what the results are because I think sometimes we make too big a deal out of something and then it’s just not the case.”

Tim Bent is the Environmental Affairs Director at Firestone Tires. He says you ought to
check your tire pressure.
“Many people don’t maintain their tires well enough. They don’t check their tire
pressure frequently enough. And that does result, not only in lower gas mileage, but
premature tire wear which could be a safety issue as well.”
Bent says you should check tire pressure once a month. How much of a difference can
it make?
“A couple p.s.i could result in a few percentage points in fuel mileage.”
And at today’s prices, that can add up at the pump.
When tires are balanced, lead weights are attached to the wheel rim. The weights make sure the tires wear evenly, and ensure a smooth ride. But the Ecology Center says the weights fall off, and the lead degrades easily, posing a risk to human health. (Photo by Mark Brush)
Lead wheel weights are about 95% lead. Two recent studies found that when the weights fall off of cars, they get ground up by traffic. Lead dust is deposited by roadways and sidewalks, and some researchers think the dust might be harmful to human health. The Ecology Center's "Lead-Free Wheels" program is trying to get tire retailers and local governments to switch to non-lead wheel weights. (Photo by Mark Brush)
For years, the government and environmentalists have been working to reduce lead exposure in the environment. Lead can cause developmental damage to children and cause other health problems. The government banned lead in gasoline. It banned lead shot in shotgun shells. There are efforts to get rid of lead sinkers in fishing tackle.

For years, the government and environmentalists have been working to reduce lead exposure in the
environment. Lead can cause developmental damage to children and cause other health problems. The
government banned lead in gasoline. It banned lead shot in shotgun shells. There are efforts to get rid of lead
sinkers in fishing tackle. And now, environmentalists are trying to ban lead weights used to balance wheels.
And some companies and fleet operators seem willing to comply. The Great Lakes Radio Consortium’s Julie
Halpert has the story about the move to a less hazardous alternative:
When you buy a new car or get your tires replaced, manufacturers use lead weights, which clip onto the wheel
rim to make sure it’s evenly balanced. They use lead, because it’s heavy, dense. So a small amount by
volume is used.
Still, a few ounces of lead can be used on each wheel. And nearly every car and truck on the road has lead
weights. They’re the second largest use of lead in cars, next to lead acid batteries.
As long as the weights stay on the tires, they’re not a huge problem. But environmentalists are worried that
they come off too often. Many fall off when a car hits a pothole or collides with a curb. Then they’re run
over, ground down and get into the environment.
Each year, roughly 30-million pounds of lead are used to make wheel weights. A recent study estimates that
more than 300 tons of lead fall off vehicles each year in the Midwest alone. Jeff Gearhart is with the Ecology
Center which conducted that study.
“Many people don’t realize there’s a lot of lead in vehicles for this particular use and this is actually a fairly
small percentage of that lead actually falls off. But when you look at it as quantity, it’s pretty significant.”
The weights don’t just pose a problem on the road. Gearhart says there’s also danger when they’re not
properly recycled when new tires are put on and the weights are replaced. Another problem is when a car is
scrapped and then later when the parts are melted down, the lead can be released into the environment.
“Lead wheel weights are not managed very well as vehicles are scrapped and the difficulty in correcting the
management of these at the end of a life in a salvage yard or in a vehicle crusher or a shredder is very
challenging.”
He says the solution is to make sure lead is not used in the first place. Concerned about lead’s potential
health effects, Europe has already decided to ban lead wheel weights starting next year. And Gearhart is
pushing manufacturers who design for the U.S. market to do the same. He says substitute materials, such as
zinc, iron and tin, are readily available and work just as well as lead.
And with funding from the Environmental Protection Agency, the Ecology Center is making lead-free weights
available to those who service vehicle fleets.
(sound of weights being hammered onto wheel rims)
At the city of Ann Arbor, Michigan’s garage, a technician is banging zinc weights onto wheels. Tom
Gibbons helps manage this fleet of 400 city vehicles. Ann Arbor is the first city to switch to lead-free
weights.
“We realize lead is a problem in the environment and in the city, we’re really concerned about the
environment. We’re committed to doing as much as we can to protect it, so if we can take lead out of the
system, why not do it.”
Gibbons says the substitutes work just as well as lead weights. He says once the Ecology Center’s free
supply of weights runs out, the city will began buying non-lead weights, even though they’ll cost slightly
more.
But not everyone agrees with the idea of using other materials for wheel weights. Daimler/Chrysler doesn’t
plan to switch to lead-free weights for its U.S. models. The company is concerned the substitutes are costlier
and more difficult to install on wheels.
Other automakers are looking at eliminating the use of lead weights. Terry Cullum is with General Motors.
He agrees they’re currently an issue, but says the Ecology Center’s estimate of the number of weights that fall
off cars seems high to him. And, he says there’s no imminent danger to the public.
“I think if you look at this from a risk-based situation, we don’t view lead being used in wheel weights
applications as a risk, well, as a large risk, let’s put it that way.”
Even so, General Motors is considering moving to lead free weights. Cullum says that everywhere the
automaker uses lead is a concern. And since the company will have to stop using lead weights on the cars and
trucks it sell in Europe, he says it might be easier just to take them out of all GM vehicles. Still, Cullum says
the substitutes present a big engineering challenge: because they’re not as dense. It takes bigger pieces of
metal to make the same weight. So, they take up more space on the wheel than lead weights.
“It becomes an issue, in terms of where do you put it on the wheel, how do you do it in such a way that it
doesn’t actually interfere with the actual operation of the wheel or the brake systems. That is an issue that is
going through research and engineering right now.”
But Cullum’s optimistic that the issue can be addressed. And other auto makers, such as Honda, are forging
ahead with lead-free weights on at least one of their model.
Still there’s resistance from U.S. tire retailers. The Tire Industry Association says the weights don’t fall off
wheels. And the tire retailers say the lead weights are properly recycled. The group has no plans to stop
using lead weights if they’re not legally required to.
Jeff Gearhart with the Ecology Center says that denial of the problem is a big mistake. He says if
manufacturers and tire retailers cooperated, they could get a substantial amount of lead out of the
environment within a few years.
“There is the potential to make a really significant impact here. We’re talking hundreds of tons of lead
released into the U.S. to the environment that can be eliminated. So we think this is a high priority project,
not just for us, but we think it will be for states and for EPA to look at how to facilitate this transition to
cleaner wheel balancing.”
The Environmental Protection Agency is starting to look at the issue. It plans to conduct a study within the
next year to get a better understanding of the problem and see how lead weights are handled. Then, they’ll
issue guidelines for consumers and tire recyclers late next year. That means the public will be more aware of
the use of lead wheel weights and the potential for toxic exposure. Usually, that means public pressure for
change, whether some automakers and tire retailers like it or not.

(tire balancing sound)
When you go to get new tires, or to have them rebalanced, the mechanic often
attaches lead weights to the wheel rims. The weights help ensure a smooth
ride and make sure tires wear evenly.
But two recent studies found some of these wheel weights fall off. The
researchers say that adds up to 275 tons of lead dropped onto roads in the
region every year. One of the studies found the soft metal gets ground up
and deposited near curbs.
Jeff Gearhart is with the Ecology Center. His group is concerned the lead
dust could be tracked into homes and washed into water supplies. So the
group is working with tire retailers to switch to non-lead wheel weights.
“Lead, in commerce, being used in a way where there’s exposure, is something
we should move away from. The European Union has banned the use of these
weights and we think that that is going to be needed in the U.S. as well.
Gearhart says the Ecology Center will help retailers cover the cost of
switching to non-lead weights.

The phrase "where the rubber meets the road" is taking on new meaning
in some states. Ohio, for example, is testing rubber in the mix of
asphalt it uses to repave roadways. Ohio and other states say this is
one way to recycle old tires. But, as the Great Lakes Radio
Consortium’s Julie Grant Cooper reports, researchers aren’t sure it’s
cost effective:
Each year in the United States alone, an estimated
two-hundred-fifty-million tires are scrapped. While some enterprising
companies have found ways to recycle them, up to eighty-percent of waste
tires still end up stockpiled or thrown away in landfills. But now some
researchers think they may have found a way to help control air
pollution with a substance made from old tires. The Great Lakes Radio
Consortium’s Wendy Nelson reports:
