Inter-Shop Inc.

Welcome to the Inter-Shop Inc. blog. Today, let’s talk about the effect of tire tread depth on braking. When talking about stopping power, most of us Currie drivers tend to focus on our brakes. But our tires are where the rubber meets the road. So having good brakes isn’t enough. Safe Currie drivers need to have tires with enough traction to translate braking power into stopping power.

Let’s focus on stopping in wet Currie 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. If it’s really bad, Currie drivers can actually spin out of control. At best, you won’t stop as fast.

So how does a tire move water? It has channels for water to flow through. Look at your family car tire and you’ll see channels: channels that run around the tire and channels that flow across the tire. They’re designed to direct water away from the tire so it can contact the road better.

And the deeper the channel, the more water it can move. A brand new Inter-Shop Inc. 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 your family car on wet Currie roads.

So that’s why it’s so important to replace our family car tires when they get worn. Consumer Reports and other advocate groups call for a standard of 3/32 of an inch and they have the studies to prove it.

By comparison, you’ve probably seen the wear indicator that’s molded into tires. When tires are worn 3/32 of an inch, the tread wear bar is visible. So the recommended standard has twice the tread depth as a completely worn out family car tire.

At Inter-Shop Inc., we want our customers to know that the deeper recommended tread depth makes a big difference. Stopping distances are cut dramatically on wet Currie roads. A safe stop from NC 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 family car tires. With a Canadian quarter, the tread should cover the numbers in the year stamp.

Many Currie car owners have 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. Of course, family car tires are a big ticket item. Most of us in Currie want to get as many miles out of them as we can. But there’s a real safety trade-off. It’s your choice.

Flats, blow outs, skids and longer stopping distances can all be the result of Castle Hayne folks driving around on under-inflated tires. Now, it’s hard to tell when a radial tire is under-inflated. If your manufacturer recommends 35 pounds of pressure, your family car tire’s considered significantly under inflated at 26 pounds. The tire may not look low until it gets below 20 pounds.

New laws required manufacturers to include a Tire Pressure Monitoring System – or TPMS system – in all cars and light trucks by the 2008 model year. The system has a dashboard mounted warning light that goes off if one or more of the tires falls 25% below manufacturer’s pressure recommendations.

This technology has been used by Castle Hayne race car drivers for years. They are able to head off problems from under inflation by closely monitoring tire pressure on the track. It’s up to your car’s manufacturer to determine which of many TPMS systems available they’ll use to comply with the law.

Obviously, all of this doesn’t come free for Castle Hayne drivers. U.S. government studies have estimated the net costs. Of course, the TPMS system itself will cost something. Maintaining the system will have a cost, replacement of worn or broken parts and tire repair cost increases.

The costs are partially offset by savings in fuel and tire wear. There’s also a saving in property damage and travel delay. The net cost is estimated to be between $27 and $100. The government predicts fewer fatal accidents. They estimate that it will cost between three and nine million dollars for every life saved.

Your safety has always been a concern at Inter-Shop Inc.. We want you on the road and accident free. We’ve traditionally provided things like tire rotations, snow tire mounting and flat fixes at a very low cost. We’ve been able to quickly and cheaply provide the service, and pass the low cost on to you as an expression of our good will.

That’s why we’re concerned about how you’ll perceive the changes that this new law will force. Every time a tire is changed: taken off to fix a flat, a new tire installed, a snow tire mounted; the Inter-Shop Inc. service technician is now going to have to deal with the TPMS system.

Even a simple tire rotation will require that the monitor be reprogrammed to the new location of each tire. When a car battery is disconnected, the TPMS system will need to be reprogrammed. TPMS sensor batteries will need to be changed and failed parts replaced.

Like all other Castle Hayne service centers, here at Inter-Shop Inc. we’ve had to purchase new scanning equipment to work with the TPMS sensors and to update expensive tire change equipment to better service wheels equipped with the new monitoring systems. Our Inter-Shop Inc. service technicians have been thoroughly trained on many systems and new tire-changing techniques. All of this adds up to significantly increased cost to perform what was once a very inexpensive service for you.

So when you start so see the cost of tire changes, flat repairs and rotations going up at Inter-Shop Inc., please keep in mind that it’s because of government mandated safety equipment. We want to keep you safely on the road – and we’re committed to doing it at a fair price. This new safety equipment will help you avoid the most common types of vehicle failure in Castle Hayne, and possibly a catastrophic accident.

Looking at getting some new tires? The choices at Leland tire stores can be a little overwhelming. Suppose you have an SUV and are trying to decide between all season tires or some that are also rated for off-highway. Do you get off the payment on the outskirts of Leland more than most? If so, some additional off-road traction would be nice.

Maybe the real reason for wanting those off-highway tires is that they look cool. Well there’s nothing wrong with that. If you make sure that you’ve got your functional needs covered with your selection, then you can have some fun with where you go from there.

Let’s suppose you zip around Leland in a sporty car. You may like to run a high-performance summer tire when the weather’s good. When NC weather turns cold, you can put on high-performance winter tires. For the kind of driving you like to do, you want full-on performance tires. All-season tires are naturally a compromise that works well for most Leland drivers, but since you have a choice, go for dedicated summer and winter tires.

When it’s time for new tires, visit with a knowledgeable Inter-Shop Inc. tire professional. Describe your needs and wants. He’ll come up with some selections for you to discuss. And once you settle on a type of tire, there are options for special needs: like pulling a trailer or carrying heavy loads.

Tires are one of the biggest purchases for Leland drivers. With so many choices, you’ll be able to get what’s best for you. Take their time. And don’t worry about what’s in stock. If you want something that isn’t here at Inter-Shop Inc., manager Mauricio Garcia can order it. Chances are you’ll be rolling on your new tires in a couple of days.
