How Do I Know What My Tire Size Is?

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 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. 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. 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. The next letter is the speed rating. Not all tires 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 you 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’re 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 a manufacturer’s product line – you can’t compare with other manufacturers. 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.

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 build up in government tests. A, B and C – from best to acceptable.

It’s safe to go with the 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 tire professional.

Differential Service: What You Need To Know

 

A Typical Vehicle DifferentialDon’t be embarrassed if you don’t know what a differential is; you will in a moment. That fact is that if you drive a car, you have a differential. Whether your vehicle is front-wheel drive, rear-wheel drive or four-wheel drive, you have a differential. You might even have two or three.

As you might guess from the name, a differential’s job is to compensate for differences. Specifically the differences in wheel speed when turning. For instance, imagine taking a corner. Your inside wheel has a shorter distance to travel than the outside wheel as you go around the corner. That means that your outside wheel has to turn faster to keep pace with the inside wheel.

The differential allows the wheels to turn at different speeds while still providing power. Without a differential, our tires would scrub and hop along the pavement during turns.

You’ve probably noticed the big bugle in the middle of the rear axle when you’re behind a truck. That’s the differential. Rear-wheel drive vehicles have a differential in back. Most four-wheel drive trucks and SUVs will also have a similar differential on the front axle.

Front-wheel drive vehicles’ differential is called a transaxle because it combines the differential and transmission in one unit. An all-wheel drive vehicle will have a differential or transfer case that adjusts for speed differences between the front and rear drive wheels.

It can seem a little complicated. But you can see that all of the engine’s power is routed through your differentials. They’re strong enough to handle the work, but they need to be properly lubricated in order to stay strong. So from time to time, you need to have your differential serviced. Buckley’s Auto Care can service your differential. The used fluid is drained and replaced with clean fluid. Some differentials also require special additives to be installed, and at Buckley’s Auto Care we can help you with that, too.

The rule of thumb for the time and mileage interval for servicing your differential can vary greatly by vehicle. A front-wheel drive vehicle’s transaxle will need servicing more frequently than the rear differential on a pick-up truck, so check with your service advisor or your owner’s manual for recommendations.

How and where you drive will have an impact as well. If you drive on dirt roads or through streams in the Wilmington area, you’ll need to service the differential at Buckley’s Auto Care much sooner than if you always stay on the local Wilmington pavement.

Toyota Recalls Pontiac Vibe In Wilmington, Delaware

2009 Pontiac Vibe

For Pontiac Vibe owners in Wilmington, Delaware, they should be made aware that the Pontiac Vibe crossover is included in Toyota Motor Corp.’s recall of sticking accelerators. Also included is the Vibe’s sister model, the Toyota Matrix. In addition, the latest recall of 2.3 million cars due to a faulty pedal design also includes 2009-10 Pontiac Vibes, according to GM spokesman Alan Adler.

GM said that it still doesn’t know exactly how many cars are affected. Adler said that Toyota found out about the recall only seven minutes before the carmaker notified the US government. Adler added that Toyota engineered and built the Vibes, which was built in Fremont, Calif., under a joint venture between GM and Toyota.

These cars are badged as Pontiacs but they are included in Toyota’s recall. GM pulled out of the joint venture, called New United Motor Manufacturing Inc., as part of its bankruptcy last year.

Adler gave assurances that once GM gets more details from Toyota on how many Vibes are in the recall and how to fix them, customers will be notified about fixing the problem at Buick-GMC dealerships.

GM is phasing out the Pontiac brand. Adler asserted that GM didn’t manufacture it, but since it sells these cars, it is responsible in making sure that “Pontiac customers are taken care of.”

If owners of Pontiac Vibes in Wilmington, Delaware have any questions regarding their vehicles, they may call Buckley’s Auto Care for assistance. They will be glad to help.

Radiator Service And Repair In Wilmington, Delaware


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, 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 goes 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 a mixture of water and antifreeze. The proper mixture keeps the coolant from either boiling away or freezing. Both of which can result in massive engine damage.

Another very important coolant issue that is often overlooked is the age of the coolant itself. antifreeze has additives that protect the coolant system from corrosion. As these additives are depleted over time, they can’t protect the radiator and other parts from rust, scaling and corrosion. Old coolant may still keep your engine cool, but it won’t protect it from corrosion.

If you see a warning message to check the coolant or if the temperature gauge is in the hot zone your cooling system needs to be checked. It’s OK to add water or antifreeze yourself. But you need to be cautious. Remember four things.

  • First, you never want to open the radiator pressure cap. You could be severely burned.
  • Second, try to get to a Wilmington service center such as Buckley’s Auto Care immediately if your coolant is low. If that is not possible, follow the directions in your owners manual – it will direct you to only make additions to the coolant overflow bottle.
  • Third, remember that you need a proper mixture of water and antifreeze. If you make an emergency addition to your cooling system, follow-up with your service center where they can make necessary corrections.
  • Fourth, not all cars use the same type of antifreeze. You need to check your owners manual to make sure you use the right kind. Mixing antifreeze types or using the wrong kind of antifreeze may void the manufacturers warranty on your cooling system. Again, another reason to rely on your Wilmington service center to do things right.

Remember, Buckley’s Auto Care has the equipment to change your coolant quickly and inexpensively. 302-999-8285

What Is A Vehicle Manufacturers Warranty?

If you own a Delaware vehicle with a warranty, beware! Many dealers and manufacturers suggest that you need to get your maintenance services at a dealership in order to keep your warranty. That simply isn’t true! You can have your vehicle serviced at your trusted, local service center without affecting your warranty. A federal law, called the Magnuson-Moss Warranty Act, prohibits a manufacturer from voiding your warranty just because you got parts or services from a non-dealer. In fact, a manufacturer can’t require you to use their brand of oil filters, lubricant, or any other part in order to maintain your warranty protection. This protection is true for aftermarket extended warranties purchased on new or used vehicles. This protection also applies to leased vehicles. There are similar laws in Canada as well.

If a manufacturer can prove that the replacement parts or service lead to a vehicle failure, they can void a portion of the warranty. Of course, Buckley’s Auto Care uses quality parts and fluids that meet or exceed manufacturers’ specifications. (See http://buckleysautocare.com/contact.html.) A lot of people do not know that service centers subscribe to data services that tell them exactly which parts and fluids meet manufacturers’ specifications. These services are updated constantly so that your Wilmington automotive service center always knows what you need for your car. You can be assured that your vehicle will receive high quality replacement parts that’ll keep you safely on the road.

Proper maintenance is so important to safety. It can also prevent costly repairs and save you money over the long haul. Just because you don’t have to go to a dealer to get your maintenance service performed doesn’t mean that you don’t need to have it done at all. In fact, some protections from your warranty require that scheduled maintenance be performed. If you miss having important work done, you may lose some warranty coverage. Refer to your owners’ manual and vehicle warranty for more details. And keep good records of the work you’ve had done.

The protection you receive under the Magnuson-Moss Warranty Act can save you hundreds of dollars each year. The average hourly labor rate for service is nearly twenty percent lower at independent service centers such as Buckley’s Auto Care. We are conveniently located at 1604 E. Newport Pike in Wilmington. So why go anywhere else?

What Is A Water Pump, Anyway?

Your cooling system is very important. It circulates coolant through the radiator and your engine to protect your car from overheating. There are five main components to the cooling system:

  • the radiator
  • the radiator cap
  • the hoses
  • the thermostat and
  • the water pump

The water pump’s like the heart of your cooling system, circulating the fluid throughout. It’s a small pump that’s driven by the engine; usually by belt, but sometimes by a chain or gear.

The water pump only operates when the engine’s running. Water pump failure is pretty routine. Some start failing at around 40,000 miles, but most fail by 100,000 miles. Consult your owners’ manual or service technician to see what’s recommended.

Since a water pump either works or it doesn’t, you need to change it when it fails. Water pumps fail in one of two ways: the bearings fail or they begin to leak. It’s possible to have a leak from a cracked water pump, but it usually leaks at the gasket where it attaches to the engine.

So how can you tell when the water pump is failing? If you can hear a low-pitched grinding sound coming from the water pump – it’s got a problem. If you can see coolant in that area, you’ve got a leak.

Some water pumps are driven off the timing belt. They might be under a plastic cover so you can’t see the water pump. Look for coolant on the driveway. If you see some, have your service center check it out.

Most timing belts need to be changed at 60,000 miles – some longer. It’s a good idea to change your water pump at the same time if it’s one of those that’s driven off the timing belt. To start with, 90% of the work’s already done with the timing belt change. And, if you don’t, and develop a leak later, you’ll have to change the belt again along with the water pump because the belt will have been contaminated by the leaking coolant.

You can replace your water pump with a brand spankin’ new one or with a rebuilt pump. Rebuilt will save you some money, but ask your technician what he thinks. Don’t feel too bad if your water pump gives out. They will all wear out eventually. Your service technician can get you back on the road and on with your life.
