Tyres

Selecting the right tyres

Selecting the right tyres for your vehicle is an important decision. Your safety, as well as driving enjoyment over the next years and thousands of miles will be determined by this decision. The information provided here and the advice/recommendations from the experts at The Kieran Farrell Tyres will ensure you select tyres that match your vehicle... and the way you drive it!

"How many tyres do I need?"

Since tyres affect the personality and performance of your vehicle, all four tyres should be as identical as possible or handling problems may arise. If your tyres don't match, it is possible that one end of your vehicle won't respond as quickly or completely as the other, making it more difficult to control

Consider the following:

JUST ONE TYRE?

If your tyres have a lot of remaining tread depth, but you need to replace just one that has been damaged by an accident, road hazard or a vandal, you should replace it with a tyre that exactly matches the others. Select a replacement tyre of the same brand, line, size and speed rating. While there may be a less expensive tyre available, it wouldn't be a bargain this time because it would be different than the other three tyres on your vehicle.

A PAIR OF TYRES?

If two of your tyres have a lot of remaining tread depth, but you need to replace the other two because they were damaged or have worn out, you should replace them with a pair of tyres that come as close as possible to matching your existing tyres. While identical new tyres are desirable, others of the same size and type can also provide good results. Only consider selecting new tyres that are from the same tyre category as your existing tyres. New tyres should be installed on the rear axle.

While your vehicle is being serviced ask your mechanic why one pair of tyres have worn faster than the others. Was it caused by a lack of tyre rotation, out-of-spec wheel alignment or loose mechanical parts? Once the problem has been found, it can be corrected before it damages your new tyres. Keep in mind that your ultimate goal is that all of your tyres always wear out at the same time so they can be replaced as a set.

A SET OF TYRES?

If all of your tyres are wearing out together, you have the greatest flexibility in tyre selection. If you were happy with the original tyres, simply replace them. If you want longer treadwear, a smoother ride or more handling, there are probably tyres that will help you accomplish that. Review the tyre category types until you find a category description that describes a tyre that fits your needs.Once you know how many tyres you will be replacing, determine size and type by answering the questions below:

What is the right size for my vehicle?

Buying the correct tyre size can get complicated, especially if you decide to upgrade from your vehicle's Original Equipment size. The expert sales team at The Kieran Farrell Tyres is always ready to offer performance and fitment advice. Call 091-755-688 .

A tyre's first requirement is that it must be able to carry the weight of your vehicle. No matter how good a tyre you select, if its capabilities are "overworked" just carrying the load, it will have little reserve capacity to help your vehicle respond to quick emergency. So when you are in the selection process, make certain that your new tyre's size is designed to carry the weight of your vehicle! Don't undersize.

The other size consideration is overall tyre diameter. Since many of the functions of today's vehicles are highly computerized, maintaining accurate speed data going into the computer assures accurate instructions coming out. And an important part of the speed equation is your tyre's overall tyre diameter.

For cars and vans, staying within a 3% diameter change is desirable. Pick-ups and sport utility vehicles (SUVs) are usually engineered to handle up to a 15% oversize tyre. Most tyre dimensions can be calculated. While at first a 3% diameter increase or reduction in tyre diameter may sound very limiting, in most cases it allows approximately a 3/4" diameter change

Additionally to help with the selection of substitute sizes, a system called "Plus Sizing" was developed. We use Plus Sizing to take into account the diameters of the available tyres and the wheels, and then helps select the appropriate tyre width that ensures adequate load capacity. Maintaining the tyre's overall diameter helps maintain accurate speed data going into the computer.

Do I need summer tyres, winter tyres, all-season tyres?

Do you drive your car only in sunshine, or also through rain and snow? Do you drive your light truck on the road, off the road, or are you the one responsible for clearing the land to build the roads? To successfully meet each of these driving conditions requyres a different type of tyre.

Ask yourself these questions to determine which performance category you should choose from:

WHAT IS THE WORST DRIVING CONDITION I WILL ENCOUNTER?

If you use more than one set of tyres and wheels (for example, summer tyres in summer and snow tyres in winter), you can select tyres that exactly meet your diverse needs. If you use one set of tyres for every season, you may get good performance under many conditions, but you will compromise your vehicle's performance when the conditions are at their worst.

So the important thing to do is to select your tyres so that they match the worst driving condition you expect to encounter. When you're stuck in the snow or in the mud because your tyres don't have the appropriate capabilities, you'll curse their limited performance in your worst driving condition...and you'll quickly forget how smooth and quiet they were at other times!

WHAT ARE THE TYPICAL DRIVING CONDITIONS I WILL ENCOUNTER?

If you only drive around your neighborhood and a "long trip" is one that's just down to the corner convenience mart, almost any tyre will do. But if you drive your vehicle on congested city streets and expressways during rush hour you will be better served by more responsive tyres. If you drive extensively on the interstates you will want quiet, smooth riding, long wearing tyres. Or if you like to drive quickly on twisting roads or through the mountains you will want good handling tyres. And if you drive on the track or in autocross events, you will want the best competition tyres available.

BALANCING THE REQUIREMENTS OF YOUR DRIVING CONDITIONS.

If your worst driving conditions and your typical conditions are similar, one set of tyres will be all you need. If you live at the edge of the snowbelt and infrequently get snow you may want to select an all-season tyre. If your SUV is used as the family's station wagon and driven on the road all of the time, overly aggressive light truck tyres aren't for you (unless you really like the "look").

If your worst driving condition occurs frequently (you drive through snow all winter) and is dissimilar to your typical driving condition (you commute to work on the expressway during the week and spend your weekends at the beach), you may want to consider selecting two sets of tyres for your vehicle. Each set will be designed to master the specific conditions without compromising your driving satisfaction at the extremes. While purchasing two sets of tyres may appear expensive, the set you're not using won't wear while you are using the other set, and combined they'll provide longer total wear than either set could individually!

How do I compare price vs. value?

Why is it that the price of fuel for our vehicle seems relatively inexpensive while the cost of its tyres seems high? (Of course you already know that The Kieran Farrell Tyres tries to keep your tyre costs as low as possible!) If we keep track of our total costs we will find that typical total fuel costs for just 10 to 20 thousand miles of driving actually exceed our tyre costs. And believe us, we've found that the quality and performance of our tyres has a lot more to do with our driving satisfaction than our fuel does.

We think that much of the misperception has to do with the fact that we buy fuel one tankful at a time, and don't really look at its total cost for thousands of miles. Our tyres are paid for "up front" and then last for tens of thousands of miles.

When you are selecting new tyres and find one that is perfect, although more expensive than another tyre that appears to be a close second; consider evaluating your situation by comparing "how much per mile" each tyre will cost. If you plan to drive your vehicle another 30,000 miles and are considering the "perfect" tyres at $100 each, and the other at $90 each; you may be surprised to find out that the cost of the "perfect" set costs just 1.3 cents per mile...while the close set costs 1.2 cents per mile. Will saving the $40 today make up for not having selected the "perfect" tyre that you will be driving on for the next two years?

THE LAW

According to most states' laws, tyres are legally worn out when they have worn down to 2/32" of remaining tread depth. To help warn drivers that their tyres have reached that point, tyres sold in North America are requyred to have molded indicators called "wear bars" across their tread pattern from their outside shoulder to inside shoulder. Wear bars are designed to visually connect the elements of the tyre's tread pattern and warn drivers when their tyres no longer meet minimum tread depth requirements

COMMON SENSE

However, as a tyre wears it is important to realize that while its dry traction and handling will improve its ability to perform in rain and snow will diminish. At 2/32" of remaining tread depth, resistance to hydroplaning in the rain at highway speeds has been significantly reduced and traction in heavy snow has been virtually eliminated.

If rain and wet roads are a concern, you should consider replacing your tyres when they reach approximately 4/32" of remaining tread depth. Since water can't be compressed, you need enough tread depth to allow it to escape through the tyre's grooves. If the water can't escape fast enough your vehicle's tyres will be forced to hydroplane (actually float) on top of the water, loosing traction.

If snow covered roads are a concern, you should consider replacing your tyres when they reach approximately 6/32" of remaining tread depth to maintain good mobility. The reason that you need more tread depth in snow is because your tyres need to compress the snow in their grooves and release it as they roll. If there isn't enough tread depth, the "bites" of snow your tyres can take on each revolution will be so small that your traction will be reduced. Because tread depth is an important element for snow traction, winter tyres start with deeper tread depths than standard all-season or summer tyres. Some winter tyres even have a series of wear bars molded in their tread pattern indicating approximately 6/32" remaining tread depth.

What Everyone Should Know About Wheel Alignment

On this vehicle, the front wheels are not aligned to the rear thrust line. This can happen from normal wear and stress, whether your vehicle has adjustable or non-adjustable rear suspension.

To steer straight ahead, you would have to steer the front wheels slightly to the right.

A common result would be that the vehicle would “dog track” and possibly “pull” to the side.

Of course, the angles are exaggerated so you can more easily see the condition. But it takes only a small misalignment to create problems.

Why Four Wheel Alignment?

Reduced Tyre Wear
Improper alignment is a major cause of premature tyre wear. Over the years, a properly aligned vehicle can add thousands of miles to tyre life.

Better Gas Mileage
Gas mileage increases as rolling resistance decreases. Total alignment sets all four wheel parallel which, along with proper inflation, minimizes rolling resistance.

Improved Handling
Does your car pull to one side? Does the steering wheel vibrate? Do you constantly have to move the steering wheel to keep your car traveling straight ahead? Many handling problems can be corrected by total alignment. With all the system components aligned properly, road shock is more efficiently absorbed for a smoother ride.

Safer Driving
A suspension system inspection is part of our alignment procedure. This allows us to spot worn parts before they cause costly problems.

Here's what we do:

For vehicles with non-adjustable rear suspensions:

  1. Angle readings are measured at all four wheels.
  2. The steering wheel is centered.
  3. Front wheels are referenced to rear thrust line and set to specifications.

Result: All four wheels are parallel and the steering wheel is centered.

For vehicles with adjustable rear suspensions:

  1. Angle readings are measured at all four wheels.
  2. Rear wheels are set to specification. (Rear thrust line corresponds to vehicle centerline.)
  3. Steering wheel is centered.
  4. Front wheels are referenced to the rear thrust line and set to specification.

Result: All four wheels are positioned straight ahead and parallel, and the steering wheel is centered

Important Questions About Wheel Alignment

Q. How importantis wheel alignment?

A. Think of it this way. Research indicates that the average car is driven about 12,000 miles per year. A car with toe alignment just 0.34 degrees (Just 0.17 inches) out of specification has dragged its tyres sideways for more than 68 miles by the end of the year!

Q. What are the “symptoms” of a car that's out of alignment?

A. Have your car checked if you notice:

  • Excessive or uneven tyre wear.
  • Steering wheel pulls to the left or right.
  • Feeling of looseness or wandering.
  • Steering wheel vibration or shimmy.
  • Steering wheel is not centered when car is moving straight ahead.

Q. How often should I have my car aligned?

A. Follow the vehicle manufacturer's recommendation noted in your owner's manual. But, as a general rule, have your vehicle's tyres checked every 10,000 miles or at least once a year.
