The Hans Imports Guide to Tire Specs

You know you need new tires, but you're not sure what type. You look at a tire to get the size: 225, 50, R, 16, 92, H. All the way to the North Kingstown service center you keep repeating it over and over. You even say it over in your mind while waiting in line. Then you get to the counter and the manager asks what size you need. Then your mind goes blank.

Tire size can be confusing for many North Kingstown drivers. There's so much on the side of the tire, and it's hard to keep straight.

Even though there's a lot on a tire - if you know what it all means, it's actually more helpful than confusing for North Kingstown tire shoppers. Let's start with the size number.

For example, let's say a tire reads: 225 50 R 16 92 H. The 225 part is the width of the tire in millimeters - the width between the sidewalls of an inflated tire with no load. The 50 is the aspect ratio - the ratio of the sidewall height to the tread width. Off-road tires will have a higher number and high performance tires will have a lower number.

The R signifies it's a radial tire. And 16 is the rim or wheel size in inches.

The 92 is the load rating index - it's the load carrying capacity of a tire. The higher the number, the more it can safely carry. Your empty vehicle can be safe with a lower number, but you'll need a higher rating if you routinely haul heavy loads around North Kingstown. The next letter is the speed rating. Not all tires sold in North Kingstown are speed rated. The ratings generally follow the alphabet: the further up the alphabet, the higher the speed rating - with the exception of H - it comes between U and V (don't ask why).

There's a lot of fine print that most North Kingstown area drivers probably need a magnifying glass to read. But there are a couple of other large print items of interest. One is the tread type: highway, mud and snow, all season, severe snow, etc.

And then there are the Uniform Tire Quality Grading System markings. The first is a tread wear index. 100 is the base line - a lower number is poorer and a higher number is better. All things being equal, a tire rated 200 would wear twice as long, on a government test track, than one rated at 100. These wear grades are only valid within the manufacturers product line - you can't compare with others. And it's important to note that a lower rating might be just what you want - a high performance, sticky tire has a softer rubber compound and won't wear as long, but boy, will it take those corners on twisting RI roads.

The next is a traction grade. This measures the tire's ability to stop on wet pavement in government tests. A - the best, B - intermediate, C - acceptable.

Temperature grade measures a tire's resistance to heat buildup in government tests. A, B and C - from best to acceptable.

It's safe for North Kingstown drivers to go with the vehicle manufacturers original equipment recommendations that came on your car. But if you want to make adjustments, you'll now be better equipped to communicate with your friendly and knowledgeable Hans Imports tire professional.

A Clean Start (Battery Cleaning)

You may be fanatical about keeping the outside of your vehicle clean.  But what about what's under the hood? Have you ever thought about how dirt and grime may be affecting your engine's components?

One of the most important parts under your hood to keep clean is your vehicle's battery.  With a daily barrage of dirt and moisture, outside parts of your battery can corrode, namely the cables and terminals.

Gases vented by batteries can also promote corrosion.  That can create connection problems and affect your vehicle's electrical system.  If corrosion is not cleaned off, it may damage wires and terminals so badly that they will stop properly conducting electricity.  At that point, they may need replacing.

When you bring your vehicle to us for a battery inspection and cleaning, we will remove any corrosion and put corrosion-resistant protection on each post. A technician will also visually inspect your battery.  Plus, we can test how much life is in your battery as part of a more comprehensive battery service. 

Batteries don't last forever and should be regularly cleaned, inspected, and tested.  Usually, they'll need to be replaced anywhere from three to five years after they were first installed, but their lifespan depends on how, where, and how much you drive.  Your battery is a very important component of your vehicle.  Keep yours in tip-top shape, and it's less likely to let you down when you need it most.

The Little Valve that Could (PCV Valve Replacement)

It's easy to get letters like PVC and PCV mixed up.  PVC is a plastic that's used in a lot of things, especially plumbing pipes.  And PCV is a valve that helps your engine burn off excess fumes rather than having them pollute our atmosphere. 

PCV stands for positive crankcase ventilation.  When your engine ignites gasoline in the cylinders, some of the gases produced make their way into the crankcase, where oil is held to lubricate the engine.  In earlier days, those gases would be vented out through a hose and go directly into the air.  It was a waste of gasoline (since about three-fourths of the gases were unburned fuel) and a nasty source of pollution.

So engineers devised a one-way valve that directed those gases back into the engine's air intake system to be burned again.  After a while, the PCV valve can get clogged up with gummy oil.  Not only does that reduce the recirculation of the gases, but it can also cause pressure in the crankcase to increase and possibly lead to an oil leak.

Signs your PCV valve has failed are oil leaks around the engine compartment or under your vehicle and poor engine performance. Your fuel economy will get worse. If you notice those signs, we can check your PCV valve. 

At the same time a technician inspects the PCV valve, they'll also check the vacuum hose that runs back to the air intake.  Plus, they'll make sure the vehicle doesn't have any other engine problems that might be contributing to your issues. 

Many technicians recommend replacing your PCV valve with each major tune-up, so you get ahead of any problems before they develop.  Now that you're an expert on PCV, it may be time to check out those PVC pipes in your bathroom!

Speak Up: Talking with Your Hans Imports Service Advisor

About 80% of the vehicles on North Kingstown roads today are behind on their preventive maintenance schedules. That translates to about 160 million vehicles in the United States that aren't performing as well as they could be - thousands right here in RI. Some of the maintenance issues are minor. Others represent serious safety concerns.

There are many reasons North Kingstown drivers neglect their routine car care. Some of the more common ones are complacency, lack of confidence, lack of trust and budget issues.

Modern vehicles are amazingly reliable compared to their older counterparts. They can run for years without any repairs, and we sometimes translate that to mean they don't need any maintenance. The trouble is that without maintenance, parts in the vehicle are gradually wearing out, fluids are getting dirty, oil is developing sludge — a lot of stuff is happening that we can't see, and it is destroying the vehicle. The first time we learn there is a problem, we have a major repair bill on our hands.

Older vehicles just couldn't keep going without frequent maintenance; they broke down without timely vehicle care. Modern vehicles are designed to keep running even when they're not fully healthy. Unfortunately, that convenience has led some of us to become complacent and ignore vehicle care — until we have to fix something. And fixing something today takes a whole lot more than it used to.

Some people in North Kingstown just don't feel comfortable taking their vehicles to their local North Kingstown service center. They don't know much about engines or auto mechanics, so they don't know what questions to ask. They don't want to appear foolish or ignorant.

Your physician doesn't expect you to understand what a ligament is or how it works. But if you have a problem with one, she's going to explain to you what it is, what's wrong with it and how it can be fixed. It's in her best interest as well as yours to do so. You'll both feel more comfortable with the treatment.

That's what you can expect from the pros at Hans Imports. They have to be highly trained and work with a lot of complex, high-tech systems. They don't expect their North Kingstown customers to understand car care. So ask questions. You need auto advice from a service specialist, just as you need medical advice from a doctor and financial advice from a financial advisor.

Which brings us to the next concern: trust. A lot of rumors fly around North Kingstown about auto repair scams. You may have heard about some local auto shops taking advantage of customers and replacing parts that weren't broken. Frankly, this is just bad business practice. North Kingstown auto service centers won't stay in business long if they're engaged in this type of activity.

It's in the best interest of North Kingstown service centers to diagnose a problem correctly and fix it right the first time. That's how they keep their businesses open.

Trust must be earned. But just as it took time for you to establish a relationship and rapport with your doctor, it will take time to build a relationship with your service center.

Also, realize that when your friendly and knowledgeable service advisor at Hans Imports recommends routine maintenance, he is generally relying on your vehicle manufacturer’s recommendations. In other words, your trust lies both with your service advisor and your vehicle manufacturer. You'll find that most of the service recommendations from Hans Imports you receive coincide with what's in your manual.

Those recommendations were set up by the engineers who designed your vehicle, not Hans Imports. The team at Hans Imports is just offering you a friendly reminder — a helpful reminder really, since most of us don't post our owner's manuals to our calendars.

Money is behind most neglect of vehicle maintenance. First, they worry that they can't afford it. Second, they worry that they're being overcharged.

The simple truth is, car care is like health care. We can't afford not to have it. Preventive maintenance is cheap compared to repair work. It extends the lives of our vehicles and saves us money on fuel. It also makes our vehicles safer to drive, which can prevent accidents. Putting off preventive maintenance can be very expensive.

North Kingstown area service centers have to be competitive. Like any business, they can't afford to overcharge customers or they go out of business. But vehicle care today does cost more in RI than it used to. Vehicles are more sophisticated, complex and high-tech. That means technicians have to be better trained. They have to purchase high-tech diagnostic equipment and tools. They have to keep up with the latest advances in vehicle engineering and subscribe to computer databases. Like any business, they also have labor costs, insurance, rent, utilities, taxes, office supplies, etc.

If you are strapped for cash, Hans Imports can offer auto advice to help you keep your car running safely and manage your budget. For example, let's say you need new brake pads, transmission service and a new cabin air filter. A technician can't ethically recommend you delay brake service: that creates a safety hazard for you and other North Kingstown drivers. You need to get that done now. But they can let you know if the transmission service can wait a month and how long you can put off changing the cabin air filter. They can also estimate what these services will cost. That gives you the time and information you need to save up for the other services.

The key to modern car care is preventive maintenance. Our modern vehicles are safer, more fuel efficient and more reliable than ever before. But to keep them that way North Kingstown drivers have to be more proactive about caring for them. It's good to know there are knowledgeable professionals at Hans Imports who can help us do just that.

Heat and your Tires (Tire Pressure Monitoring System)

With hotter weather and brutal heat waves becoming more common, the pressure in your vehicle's tires goes up.  After all, heat causes air to expand, and the air in your tires follows the laws of physics. Overinflated tires can reduce your vehicle's traction, cause a hard, punishing ride and make your tires wear out faster; all are important safety issues.

Four out of every ten drivers rarely check tire pressure. Some rely on their vehicle's tire pressure monitoring system (TPMS) to keep an eye on proper tire inflation.  But it's not designed to do that.

TPMS is a safety feature that has been required on vehicles made in 2008 or later, using sensors in the wheels that alert you to tire pressure problems.  That warning can be a light on your dash, a digital message or a readout of the pressure in each individual wheel.  But a study showed that more than 40 percent of drivers don't even know what the tire pressure monitoring light symbol looks like!

One looks like a horseshoe with an exclamation point in the middle.  The other looks like an overhead view of your vehicle with the tires at all four corners.  They may even show the inflation number (usually in pounds per square inch, or PSI).

The TPMS is designed to alert you that your tires aren't inflated within certain parameters, but the system shouldn't be a substitute for frequently having your tires checked with a tire gauge.  A TPMS light is only required to come on when a tire is 25 percent under the recommended tire pressure; by that time, you're driving on an unsafe tire and causing excessive wear.

Have your vehicle checked regularly by our professionals, and that includes tire pressure checks.  If you do see the tire pressure warning come on, have our service center look at it soon.  You may have a tire with a problem or the TPMS system may not be working right. 

Either way, since your tires are the only contact your vehicle has with the road, your safety depends a great deal on your tires being in top shape and correctly inflated.  Keep your tires properly inflated and your TPMS working to alert you of any problems. And that's not just a lot of hot air.
