Remember snow tires? They were basically just regular tires with big, knobby lugs to get them through deep snow. They were loud and rode hard, and Marietta drivers couldn’t wait to get them off the car. Then along came television advertisements for “all-season” radials. GEORGIA auto owners ran out and bought some and we thought we were done with snow tires forever.
Tires have come a long way since then. Modern winter tires sold in the Atlanta area are much better designed for the wide range of dangerous conditions that come with GEORGIA winter weather. They are made with a rubber compound that helps them stay flexible in cold weather. Regular tires become hard and stiff at Marietta temperatures below 45°F, which reduces their traction. That’s a critical concern in winter, especially with snowy or wet Marietta conditions. But it also means that Marietta motorists are better off with winter tires in cold weather even when it’s dry.
The tread design on winter tires has been improved to actually move snow, slush and water. The lugs and grooves actually throw packed snow out of the tread as the tire rotates. This means the tread is open and ready to move more snow when it rolls around again. Summer tires can actually pack up with snow, which makes them more detrimental than a bald tire.
Many winter tires use a micro-pore compound that lets the tire bite into ice and snow. They have wider grooves around the tire that help expel snow. They have a rounder casing to better cut into the surface of snow. Modern winter tires available at GEORGIA tire shops also have sipes, or thin slits cut into the tread. The edges of these sipes can grab ice and snow so that the tire retains traction on almost any surface. The sipes also help to expel water and slush from the tread. In short, a lot of time and engineering has gone into improving winter tires.
The all-season tire that is popular among Atlanta drivers is actually a compromise between summer and winter performance. This means they give adequate performance for Marietta motorists in either season, but aren’t great in either. Summer tires give great performance in hot weather, but lousy performance in winter. Marietta drivers need to put more thought into their tire choices these days, but that also means they get a lot better performance for their bucks.
If you want the performance that new winter tires can give you, you should have them properly installed at your Marietta service center or Aero Automotive. It’s best to purchase four snow tires and put them on all the wheels of your vehicle. But if you only want two, you need to put them on the rear of your vehicle, even if you drive a front-wheel drive vehicle. Marietta car owners always want to put the tires with the best traction on the rear of the vehicle.
Imagine this: You take a corner on an icy Atlanta road and your rear end starts to slide. What happened is that the front end slowed for the turn, but the rear end hasn’t figured that out yet. If you have high-traction tires on the front of your vehicle, that makes the problem worse. You’re slowing the front end faster and harder, which makes the back end fishtail even more.
Putting the higher traction tires on the rear will give Marietta car owners more control for turns, regardless of the type of vehicle driven. Of course, that makes putting high-traction tires on all of your wheels even smarter. Why not give all of your tires the best traction they can get? Some Marietta assume that four-wheel drive or all-wheel drive vehicles only need winter tires on two wheels. Why? Doesn’t it make sense to give all four wheels the same level of traction and control? Four-wheel or all-wheel drive cannot compensate for poor traction.
Another false assumption held by many Marietta auto owners is that if you have traction control and anti-lock brakes, you won’t need winter tires. Traction is important for good acceleration, steering and stopping. And tires provide traction. Traction control and anti-lock brakes can only improve on that traction. The better the traction, the better the traction control and anti-lock brakes will work. In other words, the better the tires, the better those systems will work for Marietta drivers.
A Canadian law requires all passenger vehicles, rental cars and taxis registered in Quebec to have winter tires on all four wheels from November 15th until April 1st.
If you’re shopping for winter tires and live where there is a lot of snow in GEORGIA, look for a mountain with a snowflake in it molded into the tire’s sidewall. This symbol means the tire complies with severe snow standards. All-season tires have an M&S stamped on the sidewall. M&S stands for mud and snow.
For more essential auto advice about tires for any GEORGIA season, talk to your honest Aero Automotive tire professional. They can help you settle upon the right tire for your area and for your driving needs. For the best performance from your tires, whatever the season, don’t forget preventive maintenance. Keep your tires up to pressure for best durability, safety and performance, but don’t overinflate them. Remember, good car care provides the safest road for all of us Marietta car owners.
For those of you in Marietta GEORGIA who pay attention to these things, you may have been hearing about the new direct injection engines and want to learn more about them. Some deliver the power of a V8 with the economy of a V6.
For example, in one family of engines the conventional V6 makes about 250 horsepower. The direct injection version of the same engine makes over 300 horsepower and gets essentially the same gas mileage. The turbocharged version makes over 350 horsepower.
So what are the differences from a conventional engine?
The core difference is in the fuel injection system. The system most vehicles use now is called a port injection system. The fuel injector squirts fuel into a port just outside the cylinder where it’s then drawn into the engine with the air.
With a direct injection system, the injector squirts the fuel directly into the cylinder. The gain in power and economy come because fuel injected directly into the cylinder during the combustion cycle is burned much more efficiently.
First, the fuel is squirted in at hundreds of times more pressure, so it’s atomized much better and burns cleaner and stronger. The other big advance is in electronics. Faster engine management computers can control the additional precision required to manage direct fuel injection.
Fuel injectors are precision instruments. They have to deliver a precise amount of fuel at exactly the right time. The design of the engine also dictates a particular spray pattern for the fuel. If a fuel injector is dirty or gummed up, it can’t do its job as well. That means less power and worse fuel economy for your suv and can lead to damaged fuel injectors.
Replacing fuel injectors isn’t cheap. Direct injection injectors are even more expensive because of the extremely high-pressure they use. Same thing for diesel fuel injectors; we’re talking mortgage payment-range to replace a set of diesel injectors.
A professional fuel system cleaning from Aero Automotive gets out the gum and varnish in the whole system, including the fuel injectors. Keep those injectors clean and they’ll last a long, long time.
Most Atlanta motorists know that tires wear out and that the wear has to do with tread depth. Most of us have heard that “bald” tires are dangerous, but most of us picture a tire with no tread at all when we think of a bald tire. And when we take our vehicles in for preventive maintenance, the technician tells us they’re need to be replaced long before all the tread is worn off. Just how much tire tread wear is too much? And how can you tell? Tires are expensive and their condition is important to the safe handling of a vehicle, so it’s vital for Atlanta auto owners to know the answers to these questions.
First of all, it’s essential to understand that there may be a legal limit to tread wear. If your tires are worn past this limit, you have to replace them to be in compliance with GEORGIA auto safety laws. That’s why measuring your tread wear is part of a vehicle safety inspection.
In some jurisdictions, tread must be at least 1.6 millimeters or 2/32 of an inch thick. This standard has been in effect since 1968. But this standard has recently been called into question, and some Marietta motorists are arguing that it be changed.
The safety issue that has brought this standard under scrutiny is the ability of a vehicle to stop on a wet surface. When a vehicle has trouble stopping, most Marietta motorists immediately look at the brakes as the source of the problem. But tires are crucial to safe stopping distances because they provide the traction required in a stop.
A tire’s contact with the road surface creates traction, which allows for effective braking. On a wet surface, a tire only has traction if it can get to the road’s surface. So tire tread is designed to channel water out from under the tire to allow it to stay in contact with the road. If the tire can’t shift the water, then it starts to “float.” This condition is called hydroplaning. It is very dangerous for Marietta auto owners since the vehicle won’t stop no matter how hard the driver presses the brakes. Steering control is also lost.
A recent study tested the stopping ability of a passenger car and a full-sized pick-up on a road surface covered with only a dime’s depth of water (less than a millimeter). The vehicles were traveling at 70 mph (112 kph) when they stopped on the wet surface. At 2/32 tread depth, the stopping distance was double that of a new tire. The passenger car was still traveling at 55 mph when it reached the stopping distance it experienced with new tires.
Let’s suppose that you’re on a busy Atlanta freeway in a light drizzle and a vehicle stops suddenly in front of you. You just bought new tires and you brake hard, missing the vehicle with only inches to spare. If you hadn’t bought those new tires, you would have crashed into that vehicle at 55 mph. That is a major difference.
What if your tires had a tread depth of 4/32? You would have crashed into that vehicle at 45 mph. Still not a good situation. But it’s better.
Now what if you were driving that pick-up truck? You wouldn’t have missed that vehicle in the first place, and you would have crashed at higher rates of speed in both of the other scenarios. The heavier your vehicle, the longer its stopping distance. It’s a matter of physics.
The results of this test has led Consumer Reports and others to ask that the standard for tread wear from 2/32 to 4/32. The increased standard will improve safety on the road and save lives here in GEORGIA and nationally.
Of course, until the standard changes, you’ll have to decide whether you’ll be willing to replace your tires a little sooner.
You can use a quarter to tell if your tread wear is down to 4/32. Place the quarter into the tread with George’s head toward the tire and his neck toward you. If the tread doesn’t cover George’s hairline, you’re under 4/32. With a Canadian quarter, the tread should cover the digits of the year.
You can measure the 2/32 tread wear with a penny. If the tread touches the top of Abe’s head, it’s at 2/32. Tires are a significant item for Marietta auto owners when it comes to car care. But their condition has a major impact on safety. We need to decide whether to sacrifice safety for economy. Keeping our tread wear above 4/32 is good auto advice.
All new passenger vehicles on our Marietta GEORGIA roads now have tire pressure monitoring systems – TPMS for short. They are designed to alert you if your tires are under inflated. Since they are fairly new, a lot of people have questions about TPMS.
First off, the most important thing is that you still need to check your tire pressure every week – or at least every time you gas up. The TPMS system alert comes in when your tire is twenty percent below the factory recommendation. So if the recommended pressure is thirty five pounds per square inch, the TPMS warning won’t come on until the pressure is at twenty eight pounds. That’s significantly under-inflated. Enough to raise safety concerns.
The worst is tire failure. A severely under inflated tire can overheat and fail. Also, handling degrades to the point that you may not be able to steer out of trouble. Also under-inflated tires wear out faster and they waste fuel. So it’s costly to not stay on top of proper inflation.
What’s the practical value of the TPMS system? Well, it’s twofold. First, it can alert you when your tire is losing pressure due to a puncture or a bent rim. That’s an important warning that you might not have gotten until next time you gassed up.
The second is that we all occasionally forget to check our tire pressure. So it’s a failsafe system to let you know there’s a problem brewing.
Other things can cause your TPMS system to go off. The system also monitors itself. The sensors that are mounted in the wheels have little batteries that send a signal to the monitor. The batteries go dead over time and the TPMS system will let you know. And the sensors could break. Also road salt from our Marietta GEORGIA roads can ruin them.
There’s also a hassle factor that your Marietta GEORGIA tire center has to contend with. For example, when you have your tires rotated in Marietta, the TPMS system has to be re-calibrated so that it knows which tire is on which corner of the car. Same is true for when you have new tires or winter tires installed. Flat repairs, as well.
That takes extra time. And it requires the right equipment and training. Special – and expensive – tire change machines need to be used with some sensors. It’s all complicated by the fact that there are a number of different TPMS systems in use so the tire professionals at Aero Automotive need equipment and training for each kind. Tire centers have had to raise the price of some of these basic services to offset their increased costs.
Also if you add custom wheels on your suv, you need to put in new TPMS sensors if your originals won’t work on the new rims. If you don’t your TPMS light will be on constantly and you won’t have the benefit of the warning system.
All in all, the mandated TPMS systems will save lives, so they’re worth the added hassle and expense.
Marietta motorists know that engines burn fuel to operate. Fuel is pumped from your fuel tank to your engine where it is squirted—or injected—into your engine’s cylinders. This is the function of the fuel injectors.
There are two ways to inject fuel into an engine. Fuel needs air to burn, so in the first method, fuel is injected into a port and allowed to mix with air and before it is drawn into the cylinders. In the second method, fuel is injected directly into the cylinders and mixes with air after it enters the engine.
Direct injection engines burn fuel more efficiently than conventional engines. Some models can deliver the power of a V8 with the economy of a V6.
For example, in one family of engines, the conventional version (a V6) delivers about 250 horsepower. The direct injection version delivers over 300 horsepower and gets about the same gas mileage. The turbocharged version delivers 350 horsepower.
Why the big difference in power? Direct injection systems allow fuel to be squirted into the engine at hundreds of times the pressure of a conventional engine. This atomizes the fuel better (breaks it down into tinier droplets), which means more of it gets burned, which translates to more power for your engine. It also results in cleaner emissions and improved MPG.
Fuel injectors are precision instruments. They have to deliver the right amount of fuel at exactly the time the engine needs it. They are also engineered to inject fuel with a specific spray pattern. This spray pattern allows for maximum fuel efficiency and proper atomization.
Direct injection engines require a much higher degree of precision than conventional engines. For this reason, they are equipped with more sophisticated computers.
When fuel injectors get dirty, their precision drops off. The spray pattern won’t be precise, and the timing of fuel delivery may be off. This decreases fuel efficiency and gas mileage for Marietta motorists as well as delivering less power to the engine.
Fuel injectors are not cheap to replace. Direct injection fuel injectors are even more expensive. And we’re talking a mortgage payment to buy a set of new fuel injectors for a diesel engine.
So keeping your fuel injectors clean is just good auto advice for Marietta car owners. The best way to do this is to change your air and fuel filters regularly and practice other habits of good car care and preventive maintenance at Aero Automotive in Marietta. Cleaning additives in your fuel can also help.
If you do end up with gum or varnish in your fuel system, you’ll need a professional fuel system cleaning. This will clean out your whole system, including the injectors. The good news is that with proper maintenance, your fuel injectors will last for a long time.
Are you a conscious consumer when buying a vehicle? Many people are concerned that their new car’s motor will not last 200,000 to 300,000 miles before having problems. Our team of skilled auto technicians knows that most of the work we do on cars is related to technology and not to mechanical failure.
Many Americans view their vehicles in the same way they view their kitchen appliances. They do not really give it much thought until the appliance stops working. While most people will simply replace a kitchen appliance when it starts to have problems, they usually will not buy a new car if the current one malfunctions, because a car is a higher priced item.
If you take your car to auto repair technicians, it is possible that you may not understand all the industry jargon about the repairs that your car needs. Unless you work with vehicle repair every day, you likely will not have a solid grasp of the inner workings of your car. It is also unlikely that you will know if you are getting an honest, transparent quote for the work which needs to be done.
The vehicle repair industry has a reputation for being over-priced, so many people are skeptical and concerned that they are being overcharged for repair work on their cars. There are websites and online tools that you can use to get an idea of what a certain repair job or part replacement will cost, but unless you know the exact phrasing and technical wording, you could get a wrong answer.
As a consumer, you need to be sure to get an estimate up front of the cost of any repair. In Georgia, an auto repair company cannot start work on your car unless you have approved the job. If the final repair cost will exceed 10% of the original estimate, the auto repair company is required to call you and inform you that the price will change.
