Picking the Right Tires in Fenton

Shopping for tires in Fenton can be bewildering because there are many choices. Let's simplify. There are four main classifications of tires, each designed for different purposes.

First off, there are summer tires. Those who buy summer tires in Fenton are looking for maximum summertime performance. The rubber is a little softer to help stick to the road on fast corners on MI roads. The tread has wide blocks at the shoulder to stiffen the tire in turns. The tread design can handle rain but really isn't set up for snow and ice.

Next comes winter tires. Fenton people buy winter tires because they still like performance driving when it's cold and slippery on MI roads, so they need a tread design that'll really bite into ice and snow. The rubber compound is formulated to stay pliable when temperatures drop below 45 degrees F/7 degrees C so they get great traction even on dry roads. On the other end of the winter tire spectrum are tires designed to handle well in severe ice and snow conditions.

The third category is all-season tires. Most new cars in Fenton showrooms come with all-season tires. This is a tire that is designed to be used all year round. The tread design and rubber compound is a compromise that won't give you the extreme capabilities of summer or winter tires; but if you're driving and weather conditions aren't at the extreme ends of the range, all-season tires might suit you just fine.

The last category is what you might have on your SUV or pickup. All-terrain or off-road tires are designed for both highway and off-road use – a tire that gets good traction in the dirt and on off-road obstacles, but still performs well on paved Fenton roads.

Choosing the right tire is important for Fenton car owners. Talk with your Muffler & Go tire professional about your driving requirements and receive valuable guidance on tires that will meet your needs.

Direct Fuel Injection Update from Muffler & Go

For those of you in Fenton, MI 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 fuel economy. 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 vehicle and can lead to damaged fuel injectors.

Replacing fuel injectors at Muffler & Go 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 Muffler & Go 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.

Battery Basics for Fenton

It's important for Fenton drivers to know battery basics. First, let's talk about which is harder on a battery – hot or cold MI weather. Most Fenton area drivers think it's cold weather because that's when we call on our batteries to have enough power to start a cold vehicle engine.

However, heat does more damage to a battery than cold. Truth is, our batteries start to die a little from day one. Keeping a full charge slows the process, which is hard with short Fenton trips because the alternator doesn't have time to fully recharge the battery from starting the engine. Fenton drivers can top off the charge with a computer controlled battery charger – say, once a month in the summer and every three months during the winter.

As far as how long a battery will last, statistics show that 70% have given up the ghost within four years. By that time, they aren't capable of taking a full charge like they used to, and your vehicle alternator has to work overtime to keep up. This causes your alternator to wear out early.

If you're pushing 4 to 5 years on your battery, see your friendly and knowledgeable Muffler & Go service assistant for a battery test to see if it's recommended to replace it. Not only can you avoid getting stranded with a dead battery on a MI road, but you'll save unnecessary wear and tear on your vehicle alternator.

The Muffler & Go 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 Fenton 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 Fenton 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 Fenton 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 Fenton. The next letter is the speed rating. Not all tires sold in Fenton 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 Fenton 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 MI 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 Fenton 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 Muffler & Go tire professional.
