Well, we all know the answer to that one. And in this issue of Real Answers, we're going to explore some of the toughest going in the trucking business.

Not every truck tire runs on the interstates at highway speeds. In fact, as we'll see in the story on Shaughnessy & Co., some truck tires don't run on trucks at all. We'll learn how Shaughnessy can carry such heavy loads without having to use special tires.

We'll also take a trip to America's "last frontier," to visit with Silver Bay Logging, a company whose operations cover thousands of square miles, but whose longest truck trips are usually less than a hundred miles—over some of the roughest roads in the world.

Our friends at Peterbilt Motors Company will share with us what they do to make vehicles stand up to the kind of torture that construction, logging and refuse haulers can dish out.

And, we'll take a look at another kind of "rough" environment, several thousand acres of wilderness that Bridgestone recently donated to the state of Tennessee for a wildlife preserve.

In our continuing series on preventing irregular wear, we'll see how alignment affects tire wear, and because we're such sticklers about proper inflation pressure, the Tire Doctor will show you how to build a master air pressure gauge you can use to check the accuracy of all your stick and dial gauges.

Finally, we'll see how a tire that looks fine on the outside may be carrying hidden internal damage—as a result of severe service.

It's a tough job, but we're up to it, so let's get going!
