Talk to Matt Davis Auto About New Shoes for Your Vehicle

Custom wheels are one way that Garner folks express themselves and personalize their vehicle. But they aren't as cheap and easy as sticking decals on your back window. There are several factors that need to be considered, including cost, the fit of the wheel, modifications that will have to be made to the vehicle, how the new wheels and tires will affect the operation of the vehicle, your driving habits and, of course, the style of the wheels. Most Garner drivers start with the last factor: the style of the wheels. But that should be the last thing we choose.

When considering custom wheels, you should first carefully consider your budget. Some wheels may require adjustments to your vehicle suspension system, brakes, or traction systems. You need to know what you can afford before you start shopping or get your heart set on a particular type of wheel.

There are three basic ways you can change your wheels. First, you choose a wheel that is already the same size as the ones on your vehicle. Second, you can choose larger wheels and third, you can choose smaller wheels. Mounting wheels that are the same size as the ones already on your car sounds easy enough. But even though the wheel may be the same diameter as your current wheels, that doesn't mean it will fit your vehicle. Besides diameter, wheels also have an offset. This is the measurement from the inside edge of the wheel to the point at which it bolts on. If your new wheel does not have the same offset as your current wheels, your vehicle tires can rub on the inside or outside of the wheel well. This can lead to blowouts, uneven tread wear and other mechanical problems.

The tire and wheel professionals in Garner at Matt Davis Auto on 875 US Highway 70 W can help you select a wheel that has both the correct diameter and offset for your vehicle. Or, if you really want a specific wheel in spite of the offset difference, your technician may be able to install adapters that will make the wheels fit.

Mounting larger wheels is a more involved process. There are several ways of doing this. You can mount larger wheels but keep the overall tire diameter the same. Or you can “supersize” your tire/wheel combo. Mounting larger wheels while maintaining the same overall tire diameter is the easiest way to increase wheel size. You still need to adjust for offset. Generally, this alteration means that your new tires will be wider than the originals, so you will have to install adapters to keep them from rubbing on the wheel wells. Consult your service advisor at Matt Davis Auto by calling (919) 600-5125.

If you want to install larger wheels and increase the overall tire diameter, it is important that the package fits in the wheel well; you may have to do some minor modifications to your suspension. More importantly, you will have to reprogram your vehicle engine's computer to calibrate for the larger tire size. The computer calculates your speed based on the rotation of your tires, so increasing the size of the tires will render it inaccurate. Inaccurate speed calculations can mess up your anti-lock brakes and your stability control systems, as well as your speedometer and odometer.

As you can see, the more modifications you make, the more it becomes important to have your friendly and knowledgeable Matt Davis Auto tire and wheel professional help you with your car care.

If you really want those “super-sized” tires, great: just factor in the issues listed above, plus you may have to have modifications done to your suspension system.

The larger wheels and tires will add weight to your vehicle. This weight is not held up by the suspension system, so is referred to as “unsprung” weight. Adding unsprung weight affects your car differently than just adding loads inside of your car. Unsprung weight can affect acceleration and braking. Putting large wheels on your vehicle may require an upgraded brake system.

Also, you may not get the performance from your vehicle that you've been used to. It may be sluggish when accelerating or harder to handle when turning. You may also find that the ride is bumpier than it was before. Of course, done right at Matt Davis Auto, a good wheel job can sometimes improve a vehicle's ride or performance. It just depends on your vehicle, the type of wheels you choose and what you are hoping to accomplish.

Now let's suppose you want smaller wheels on your vehicle. That should be easier, right? Not really. You still have to worry about offset, and it is important that your computer be reprogrammed to account for calibration issues. And you may need adjustments to your suspension system.

Remember your budget? All of these scenarios require that you shell out some money. Perhaps now you can see why it is good auto advice for Garner drivers to make that consideration first, before setting their heart on a specific type of wheel.

Another consideration should always be your driving habits. Do you do a lot of off-roading on the outskirts of Garner? Do you carry heavy loads? Do you tow a trailer on NC roads? All of these factors must be considered when replacing your tires and wheels. Some wheels just may not be up to the work you need them to do.

For example, if you mount large rims on your vehicle, then add low-profile tires to avoid major adjustments to other systems, they won't be able to handle off-roading as well as larger tires. There won't be enough sidewall on the tires to absorb the impact from off-roading. You could end up with dented or broken rims.

At the end of the day, Garner drivers should always put safety ahead of appearance. That's why you shouldn't add custom wheels to your vehicle without consulting with your Matt Davis Auto tire and wheel professional. Cutting corners when installing custom wheels by not making necessary adjustments to all of the systems impacted by the change can result in dangerous operating conditions as well as repairs down the road.

The friendly and knowledgeable auto professionals at Matt Davis Auto want to remind Garner drivers of the basics of vehicle safety: preventive maintenance, emergency preparedness and professional repairs. Stay safe, and stay on the road.

A Stitch in Time at Matt Davis Auto

You probably have heard that expression, "A stitch in time saves nine." In other words, if you fix an issue at its early stages, it will prevent a much more difficult problem later. That's certainly the case with your vehicle, and here's a true story to demonstrate it.

A driver noticed his vehicle was due for an oil change, so he took it in to his service facility early in the morning so he could wait while the work was performed. The technician routinely checks the battery on vehicles just before extreme weather is approaching (cold or hot), so with winter coming up, he hooked up the load tester (it measures voltage while a load is put on the battery). It showed the battery wasn't holding a charge well.

The technician checked the manufacturing date on the battery, too (most batteries have a date stamped in code somewhere on them). The date showed it was five years old. While batteries can last more than five years, many technicians say you should expect to get anywhere from three to six years out of them, depending on what they go through.

So, this battery was getting a little long in the tooth, and it wasn't holding a charge particularly well. But how much current was it being sent by the vehicle's alternator? If it wasn't getting enough, that might be a factor. A test of the charging system showed the alternator was putting out the correct amount of power. The technician recommended replacing the battery, and the driver agreed.

That was the stitch in time. Had the technician not checked the battery, that driver likely would have been stranded the next time he tried to start his vehicle on a very cold day. What originally was supposed to be just an oil change led to a technician's sharp diagnosis and a little preventative maintenance for one fortunate driver. Sometimes timing is everything.

The Best Test

Would you buy a jacket without even trying it on? Probably not, but it might surprise you that one study shows about half the people buy a vehicle after a short test drive around the block or none at all.  If you're in the market for another vehicle, make sure you check out the most important things so you'll know if that's the right vehicle for you.

Check out the gadgets.  Love a good sound system? Then turn it up loud.  Does it have enough bass for you? See how you like its navigation system if it has one.  Try pairing your Bluetooth smartphone with the vehicle.  Test out how to set the cruise control and how steady it keeps the speed. Back up and check out the rearview camera. If you buy this vehicle, you'll have to live with all of these things every time you drive.

Test the vehicle on roads you know.  See how it handles bumps and potholes, how it takes that tight curve that you drive every day to and from work.  Driving on familiar roads gives you a chance to compare what you know with what you're thinking about buying.

Check the fit.  One suburban driver drove a full-sized SUV and loved it until they got it home and realized it was too high for her old garage.  Remodeling the garage would be the only answer! Try installing your child seats.  Size matters, especially in a vehicle.

Gauge the fuel economy. Many vehicles have a trip computer that will calculate fuel economy quickly.  Here's a tip: you can reset it before your test drive and when you're finished, check it and see what fuel economy you got.  It will be a smaller sampling than would be ideal, but it will give you an idea.

Take as much time as you can.  A lot of sellers will pressure you to restrict your test drive to 10-15 minutes.  Ideally, you'd like to have that vehicle for a week, but that's usually not possible. So try for something in between. Remember, this could be your vehicle for years to come.

Keep in mind that every vehicle will feel strange to you at first. Buying a vehicle is a little like getting married.  You want that marriage to be happy, and you want it to last, so take the time to get to know it as well as you can.

Straight and True in Garner: Wheel Alignment

Most Garner folks worry about running out of gas or having a breakdown on the side of the road. That is why we practice preventive maintenance on our vehicles — that and to keep our repair bills down. But one important part of preventive maintenance that may get overlooked by drivers in Garner is a periodic alignment inspection.

Poor alignment causes tires to wear rapidly, unevenly or both. This means they will have to be replaced early, and new tires are more expensive than an alignment check in Garner. Bad alignment can also cause damage to suspension and steering systems, which can be expensive to repair in Garner.

Tire wear on misaligned wheels can also lead to blowouts, which are dangerous, can lead to serious accidents and can seriously damage your vehicle. Also, poor alignment itself can be the cause of an accident since the vehicle may not steer properly.

One or more wheels on your vehicle can be knocked out of alignment by running over a curb or a pothole on a bumpy Garner street. An accident —  even a minor one — that involves a wheel on your car can lead to misalignment. The small bumps and bangs of everyday driving can also gradually put your wheels out of alignment.

If you have had wheel damage to your vehicle, or if you suspect that your wheels are out of alignment, you should get your alignment checked NOW. Any service center will give you that piece of auto advice. But good vehicle care suggests that you also get your alignment inspected on a regular basis. At Matt Davis Auto in Garner, we can take care of that for you.

Your owner's manual or Matt Davis Auto can give you a suggestion on how often your alignment should be checked. If it doesn't, then once a year is a good rule of thumb. However, if you drive a lot — and especially if you drive on rough surfaces a lot — then you may want to consider alignment more often. Ask the pros at Matt Davis Auto for a recommendation.

If your vehicle is out of alignment, one or more of the wheels is not tracking correctly and will “pull” against the others. Thus, one sign of poor alignment is that your vehicle pulls to one side when you drive around Garner. Also, if you are driving a straight path and your steering wheel is off-center, that usually indicates an alignment problem.

Garner drivers should also check the wear on their tires. If they seem to be wearing out too quickly, or if you notice that a tire is wearing on one side more than the other, you should get your alignment checked.

When you get an alignment inspection, your vehicle will be put on a rack and all the parts of the steering and suspension systems will be inspected for wear or damage. The alignment of the tires will be charted and compared to the original factory settings. If no repairs are needed on the steering or suspension systems, the wheels will then be adjusted to bring them back into alignment.

This may seem like a lot of bother for drivers, but it's a lot less trouble than a blowout or an accident. The old adage is good auto advice for all Garner residents: an ounce of prevention is worth a pound of cure.

So keep on driving, and keep all four tires on the road.

What Is an EGR Valve? (EGR Valve Service)

If you've ever felt your vehicle hesitate, go, then hesitate again, you might think there's something wrong with the transmission.  After all, it's not moving smoothly  down the road.  But there are plenty of malfunctions that can cause those symptoms, one of them being something you may have never heard of: the EGR valve.

EGR stands for Exhaust Gas Recirculation. It's a system that channels small amounts of exhaust back into the engine to cool down the cylinders and reduce polluting gases.  Those include nitrogen oxides that can cause smog. The EGR valve regulates how much of the vehicle's exhaust gas is recirculated. After years and long distances traveled, that valve can get clogged or fail. Sometimes the EGR valve can stick open.  When the EGR valve isn't working properly, your vehicle can start releasing those nitrogen oxides and pollute the air.

The symptoms of a malfunctioning EGR valve include:

• Engine losing power
• Engine idling roughly
• Pinging and knocking sounds in the engine
• Stalling and hesitation
• Fuel economy decreasing
• Check Engine light illuminated

Depending on its condition, the EGR valve can be cleaned or it may need to be replaced.  Consult with your service advisor to see what options are recommended to you.

The EGR system is part of your vehicle's pollution and emissions control equipment. If you care about keeping our planet's atmosphere clean, you'll want to make sure it's doing its job—for everyone's benefit.
