By the Numbers: Tire Replacement at Allen's Automotive Center in Memphis

Ever notice that your tire is covered with writing? It's like some hieroglyphic art form. Of course, Memphis drivers know that it's not just graffiti, but to most of us, it might as well be. Would you like to know what all those codes on your tire mean? It won't lead you to buried treasure, but it could help you make a better tire purchase at your local Memphis tire store.Prominently featured on your tire is a set of numbers and letters that looks something like this: 225 50 R 16 92 H. The first number is the width of the tire in millimeters, or the width between the sidewalls of the tire when it is fully inflated and not carrying a load. When Memphis drivers replace tires, they need to match this width number, or the tires won't fit properly in the wheel wells.The 50 is the aspect ratio of the tire, which is measured by taking the height of the sidewalls and dividing it by the tread width. If you drive off-road around the Memphis area, it should have a high aspect ratio. For high perf ... read more

Fuel System Cleaning at Allen's Automotive Center

Is your vehicle sometimes hard to start early in the morning? When you turn the key, does it hesitate or stutter? If so, the problem could be the result of a dirty fuel system. Your vehicle's fuel system starts with the air filter and ends in the top of your engine. Over time, different parts of the system get dirty, which robs you of performance and hurts your fuel economy. Most Memphis vehicles have fuel injectors, rather than a carburetor. Fuel injection systems have fewer problems and require less adjustment. But they still need to be properly maintained. This is why your owner's manual has a schedule for cleaning your fuel injectors and other parts of your fuel system.Some Memphis residents are interested in buying fuel system cleaners that they can pour into their gas tank. You can do that - and there are lots of great products available that can help maintain an already clean fuel system - but these products cannot do a major cleaning. For that, you need to see Allen's ... read more

Fuel Injection: It Keeps Getting Better for Memphis Drivers

Memphis residents know that engines need to burn fuel to operate. Fuel is pumped from your fuel tank to your vehicle 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 airbefore 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 vehicle engine.Direct injection engines burn fuel more efficiently than conventional vehicle 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.Wh ... read more

Shake It up in Memphis!: Why Wheel Balancing

Our vehicles are not massage chairs. While we may enjoy a good vibration in an overstuffed recliner, we generally want as smooth a ride as possible in our vehicles. One way to achieve this is to keep a vehicle's wheels in balance. When a tire is mounted onto a wheel, it is usually out of balance. This means that as the wheel spins, there is a slight wobble to the path of the tire. For best handling performance and safety on the road, Memphis drivers want to minimize this wobble as much as possible. So we balance our tires. To balance a tire, your technician at Allen's Automotive Center spins it on a machine or drum to determine where it is off-balance. He then attaches weights that counter-balance the uneven weight. Most people in Memphis are surprised at how much balancing improves the smoothness of their ride. High-quality tires generally hold their balance well. But over time, wear and tear take their toll and tires can become unbalanced. Memphis drivers can t ... read more

Allen's Automotive Center Radiator Service

The coolant system is a vital part of your vehicle. It is also the second most common cause for vehicle failures. Even though coolant system failure is fairly common in Memphis, it is easy to prevent. The most recognizable part of the coolant system is the radiator. It is connected to the engine with hoses and is filled with coolant. The coolant draws heat off the engine and then passes into the radiator. Air passes through cooling fins to reduce the temperature of the coolant and then it's back to the engine again.There are several ways for the cooling system to fail. Most common is with the coolant itself. Coolant is comprised of water and antifreeze. The proper ratio keeps the coolant from either boiling away or freezing. Understandably, either can lead to massive engine damage.Another coolant issue that is often overlooked by Memphis drivers is the age of the coolant itself. Antifreeze has additives that protect the coolant system from corrosion. As these additives ... read more
