Selecting New Tires and Wheels

Some of us Farmington drivers just love tires. All those little rubber hairs on new tires and the smell is wonderful. We live in a great time for tires. No matter how you drive around MI, where you want to go or the look you're after; there is a tire for you.

The same is true about wheels. The hardest part is choosing from the thousands of wheels available at MI tire shops.

The team at Darrell's Firestone can help you get some things in mind before you make a purchase. Let's start with function and think about how you drive.

For example, maybe you have a large SUV but you don't drive off-road around MI, so an off-road tread isn't important. Also, because you are not out bouncing over rocks in the MI backcountry, you don't need a high profile tire to protect your rims. So that means you can probably go with the low-wide look.

If you have a winter season with rain and snow or if you find you need better ice and snow performance, they make great, high-performance snow tires that won't make it look like you are driving a tractor.

There really are a lot of options for any given vehicle. Farmington drivers will find it very helpful to have a discussion like this with their Farmington tire pro or the tire experts at Darrell's Firestone when they need new tires. You can find the best solutions for your driving needs and to make improvements in ride or handling.

Picking a wheel that is the same size as what you are now running on is important and pretty simple. But, it gets trickier if you want to upsize. Just get some help when you go bigger. All that tire and wheel still needs to fit in the available space. You do not want your tires to rub when you turn or hit a bump. Farmington drivers also need to make sure their brakes and suspension bits will fit with their wheel of choice. It doesn't matter how great your car looks if it's not drivable.

Taller, wider wheels and tires probably weigh more than your stock shoes. And it's "unsprung" weight that has a big impact on brake performance. The upsized shoes increase rotational inertia; if you go too big you may need to upgrade your brakes to compensate.

Another possible problem is an inaccurate speedometer. This happens because the number of rotations can change with the new wheels. Fortunately, speedometers and odometers are all controlled by the engine computer; so they need to get reprogrammed at Darrell's Firestone to compensate for the bigger tires.

No matter what you are after: low cost, long life, high performance, traction or stunning good looks, your wheel and tire professional at Darrell's Firestone in Farmington, MI, can help identify your needs and give you a custom fit. With all the options available, you don't have to compromise. There is a tire out there with your name on it!

Darrell's Firestone: Good Service and Good Fuel Economy

Most Farmington auto owners want to save on gas and seek our advice on improving economy. At Darrell's Firestone, we are frequently asked, however, if it is really worth the extra effort. Just how much money can Farmington drivers actually save?

In today's Darrell's Firestone article, we're focusing on the things you can do to improve your vehicle’s economy driving around MI. We'll tell you the potential savings per gallon of gas at $3.50, and we'll show a chart that also shows the savings at $3.00 and $4.00.

DOLLARS PER GALLON $3.00 / $3.50 / $4.00

TUNE UP 4%.12.14.16

The next item is replacing a clogged engine air filter. Your engine needs enough air to burn fuel efficiently for the best mileage. A clean air filter means you get plenty of air. The fact that the air's clean protects your engine. That can save you up to 10 percent or 35 cents a gallon.

DOLLARS PER GALLON$3.00 / $3.50 / $4.00

AIR FILTER 10%.30.35.40

Fixing a faulty oxygen sensor can improve economy by up to 40 percent. That's a whopping $1.40 in savings per gallon. Bring your car to Darrell's Firestone in Farmington and we'll check your oxygen sensor.

DOLLARS PER GALLON$3.00 / $3.50 / $4.00

FAULTY O2 SENSOR 40%1.201.401.60

Chances are that if your oxygen sensor is kaput your Check Engine light will come on. Now, there are any number of things that could cause your Check Engine light to come on besides oxygen sensor problems. But if it's on, get it checked out as soon as you can at Darrell's Firestone.

Here's an easy one for Farmington auto owners. Inflate your tires to the recommended pressure. That could save you three percent or 11 cents a gallon. Even a little drop in pressure will bring down your economy, so check your tires every week.

DOLLARS PER GALLON$3.00 / $3.50 / $4.00

TIRE INFLATION 3%.09.11.12

Your vehicle has recommended a specific weight of motor oil. The recommendation is based on engine design and will give you the best protection. Using a heavier weight could cost one to two percent in reduced economy, or up to seven cents a gallon.

Another thing Farmington vehicle owners can do to improve that costs nothing is to toss the junk out of our trunks. In other words, clean out the car and stop hauling around non-essentials. Don't treat your vehicle like a storage locker. Dumping 100 pounds of extra weight adds up to a 2% savings at the pump.

So when you tell someone you were going somewhere anyway and they're welcome to come along, that's okay. But if someone tells you they need to come along and it's no harm to you since you were going anyway—well, now you can tell them, “Sorry, dude, but you're an extra fifteen cents a gallon!”

All joking aside, let's all do ourselves a favor and fatten up our wallets by practicing good car care and better driving habits in MI.

New Life for Your Older Car in Farmington

Isn't it amazing how much of our stuff is disposable these days? Clothes, electronics, housewares, furniture.

Remember the days when Farmington families mended their clothes, polished their shoes and neatly put away their toys every night? If something was lost or ruined through neglect, your parents just told you to do without, that you should have taken better care of it. They considered the loss a “life lesson.”

But today many Farmington drivers tend to neglect one of the more expensive and important purchases we make: our vehicles. Vehicles are a lot more reliable today than back when we polished our shoes, and that reliability can sometimes make us take them for granted. Drivers in Farmington neglect good vehicle care practices and procrastinate when it comes to preventive maintenance. What we're really doing is heading straight for one of those dreaded “life lessons.” Eventually we'll pay for our neglect in repair bills and a shorter life for our vehicle.

Is procrastinating on routine maintenance really so terrible? Consider what happens when you procrastinate on brushing your teeth, washing your clothes or getting the dishes done. Gunk builds up, makes the job harder and ultimately damages your teeth, clothing or dishes. It's the same with your vehicle. Some of the best auto advice out there for Farmington drivers is to stay on top of routine oil changes by bringing their car into Darrell's Firestone. Even a little extra interval between oil changes can result in oil sludge, which can clog passages in your engine. This means oil can't get to some of the engine components, and they'll wear out faster without lubrication. Every time you put off an oil change, the problem gets worse, eventually cutting years off the life of your engine.

The same is true if you skip cooling system service. Corrosion inhibitors in the fluid become depleted over time, opening the system up to damage. Consistent neglect will lead to holes in your radiator. Talk to your friendly service advisor at Darrell's Firestone for suggestions and feedback.

Neglect of other fluids can also result in engine damage. Brake fluid, transmission fluid, differential fluid—all of these need to be serviced on a regular basis. In addition, your fuel system needs periodic cleaning or it can start to break down and cause permanent damage to your engine.

The good news is that it's never too late to get on track and start getting good, regular preventive maintenance for your vehicle at Darrell's Firestone. You may not be able to reverse damage that's already been done, but you can prevent further damage.

It really does all start with an oil change. With a full-service oil change at Darrell's Firestone, your fluids will be checked and your car inspected for wear and tear. Our pros at Darrell's Firestone can also advise you of other inspections and maintenance items that are coming due. If you're on top of oil changes, your service advisor will keep track of your maintenance schedule and remind you what needs to be done.

Older vehicles are going to need repairs. But with good maintenance, those repairs will involve fairly routine stuff like alternators, water pumps, belts and batteries. The cost of these replacement parts at Darrell's Firestone is much cheaper than the repair bills that come with serious engine damage, and they're certainly less than the cost of a new car.

We may not need to polish our shoes anymore, and tossing out that outdated cell phone may not be such a loss. But when it comes to our vehicles, they're just too valuable to be treated as disposable. Let's take a step back, listen to our parents and take care of our stuff. If we don't, we could be on our way to a “life lesson” involving our bank account and a bus pass.

Time for Differential Service at Darrell's Firestone?

Hello Farmington - let's talk differentials. If you have a rear-wheel drive vehicle, your differential is on the back axle. With front-wheel drive cars, the differential is up front. All-wheel drive and 4-wheel drive vehicles have three differentials - front, rear and in the middle. So you see, you've got a differential (or two or three) and it needs service now and then.

What does your vehicle differential do? Well, it compensates for the differences in speed between your outer and inner wheels in a turn. Using the dimensions of a typical car, let's compare the distance the wheels travel from the start of a turn through to the completion of the turn.

The inside wheel travels about 12.6 feet/3.8 meters. How much farther does the outside wheel travel? About 18.8 feet/5.7 meters – over 6 feet/1.9 meters more. This means the outer tire has to rotate 9 times in the same amount of time that the inner tire has to rotate only 6 times - so the outer tire has to spin faster in order to keep up. The differential makes this possible.

The gears in the differential are cooled and lubricated by differential fluid. It's this fluid that needs to be serviced. Small bits of the gears break off and are suspended in the differential fluid. The dirtier the fluid, the faster the gears wear.

So your Darrell's Firestone technician drains the old fluid out and replaces it with fresh fluid. Some differentials also need a special additive that is put in at this time.

So when should you have your vehicle differential serviced? Intervals vary from vehicle to vehicle – and may be as short as 15,000 miles/24,000 km – so check your vehicle owner's manual or ask us at Darrell's Firestone. If you frequently drive with heavy loads, tow a trailer or drive in hot MI conditions, you may need to change differential fluid more often. Servicing your differential on schedule at Darrell's Firestone can save a pricey replacement down the road.

Give us a call.
