Aftermarket Wheels and Tyres

01 Jan

Wheels and Tyres

At the end of the day wheels are a necessity. Some people prefer to use steel wheels due to their basic design however recently there has been an increased used of alloy wheels both from factory and also the aftermarket demand has picked up especially from the American Markets.. Many people are now choosing to install aftermarket wheels to enhance the look and performance of their vehicle and this is where this entry will come into the puzzle. I’m sure all of you who are reading this will have seen MTV’s Pimp My Ride, and for them, the wheels and tyres department is a big part of their car transformation and I hope to help you on how to go about picking a set of wheels that will fit your car like a glove.

With regards to wheels, there is such a vast choice of wheels. They are based upon size of the actual wheel, the number of studs and the offset. The size of wheels varies greatly and is measured in inches. You can get wheels as small as 14 inch alloy wheels and smaller and go in excess of 22 inch alloy wheels. The number of studs a wheel has is specific to each car. For example, I drive a Smart. These cars from factory come with 3-stud fitment, however is it possible to obtain hub-adaptors. These adaptors basically transform the 3-stud fitting to either 4 or 5 studs (from my research, this is what I have managed to find.) However, the use of adaptors it has been recommended that the adaptors be only used for show use. This more than a legal issue is based upon safety. I recommend that if you can find a set of wheels that have the correct number of studs that you choose these. Alloy wheels that are directly able to fit to your car are a lot safer for you and your vehicle. Aside from the width of the wheels it is vital that the offset be accurate for your car. If the correct offset isn’t used then you run the risk of wearing out your wheel bearings due to improper load of weight. check out wheels killeen

Wheel construction

There are many ways of constructing alloy wheels. The way that they wheels are constructed effect the weight and price of the overall wheel. It may seem like it’s an obvious concept that the wheels are all made the same but due to demands from the motorsport industry for example, there have been major enhancements in wheel manufacturing technology.


Casting alloy wheels will result in a one piece wheel. This involves the molten aluminum being poured into a mould. There are several ways of casting methods used; ranging from Gravity Casting and Low Pressure Casting to forged wheels. Gravity Casting involves filling a cast with molten aluminum and letting the force of gravity fill the mould. As a result, this method has the cheapest production cost of any method of alloy wheel and this saving is passed on to the buyer. Low pressure casting involves changing the pressure of the mould to move the molten aluminum into the cast. This method is commonly used with OEM alloy wheels and this method has started to become used more regularly with aftermarket manufactures due to this method being cost-effective as well as being lighter than using gravity casting. Rim rolling technology starts with a low pressure casting method but then the wheel is reheated and rollers are applied. This method has been used by manufactures in formula one wheel for several years. The last method of casting wheels is forging. Although there are various methods for casting wheels. Essentially, it is a solid billet of aluminum with pressure applied to form the shape of the wheel. As a result, the benefit of this is that the density will be higher than any of the other casting methods.

Tires Exposed – Insider Secrets to Buying the Right Tire

01 Jan

Every car sold comes with tires, right? It is hard to drive off the lot without them. The reality is that it is only a matter of time before you start giving some thought to upgrading to performance tires, or maybe you just need a new set. Does the thought of buying tires or auto parts make you as frightened as an acrophobic going to the top of Sears Tower? Calm down. Take a deep breath because Dr. Drivewire will explain all of the insider secrets you need to know about purchasing the best tire for your needs.

In two short minutes you’ll have your masters in tireology. You will have all the skills you need to pour through the product specifications, eliminate the middle man and buy with confidence from a secure online store. Premiere online retailers offer off dealer pricing, real time inventory, free shipping and rush delivery.

Reading the Sidewall

The side of your tire contains a wealth of information. Here’s an example of a tire sidewall, in this case a Bridgestone Potenza S-02 P205/55ZR14

a – The brand or model of tire.

b – This is a tubeless tire. Almost all tires today are tubeless.

c – The arrow on the tire indicates that the tire is unidirectional and must be mounted so that the arrow points toward the front of the car.

d – “P” means passenger tire.

e – Indicates how wide the tire is in millimeters. Also referred to as section width.

f – The tire’s aspect ratio, or profile. Basically, how tall the tire is.

The number is actually a percentage of the width. This tire is 55% as tall as it is wide.

g – The Z indicates the tire’s speed rating. (See Tire Ratings below for speed ratings.)

h – R simply means that this tire is a radial.

I – The diameter of wheel that this tire is intended to fit. In this case 14.

Tire Ratings


Consumer magazines, tire retailers and Dr. Drivewire frequently use the UTQG ratings when comparing tires. The initials stand for Uniform Tire Quality Grading, a quality rating system developed by the Department of Transportation (DOT). The system was designed to provide information to consumers as to the relative performance of passenger tires in the areas of treadwear, traction and temperature. The UTQG ratings are most valuable when comparing how a manufacturer’s tires rate within its own product line rather than as a comparison between brands. UTQG is just one tool to use when selecting tires and it should not be your only guide.

Winter Tires – Snow Tires Are Critical Equipment

01 Jan

Most new cars that are sold today are equipped with All-Season tires. In fact All-Season tires are a more popular choice than winter tires and summer tires in aftermarket purchases as well. In large part this is a good solution for drivers because many parts of the country do not see harsh winter weather conditions and even those areas of the country that do experience significant snow and ice still have the majority of the year without those conditions. Winter tires are neither necessary nor appropriate in late spring, summer and early fall even in colder regions. The implication of an “All Season” tire is that it is designed for all seasons. This is probably true for most people who live in the lower half of the U.S. but it could be misleading for our friends in the north and mountainous regions that get significant snow and ice.

Winter tires are specifically designed to grab snow and ice. Unlike an all season or summer tire, a snow tire is manufactured with a softer, more flexible rubber formula more suitable to cold weather. Using this compound, a winter tire retains its traction capabilities to hold the road better and to grip snow and ice. A summer or all season tire will tend to become more brittle and inflexible in cold temperatures and therefore it will slide much quicker. The ability to bite into snow and ice and to conform to the road is critical in the winter to avoid getting stuck, to steer and corner effectively and to stop. A tire not made specifically for cold weather cannot function effectively in winter stopping and cornering. Many newer cars are equipped with features like antilock brakes; stability control and even all wheel drive to help with effective maneuvering however, these systems are only as effective as the tires upon which all the systems are dependent. Picture an emergency room equipped with all the latest and best equipment ready to take care of any emergency thrust upon it. However, this ER is staffed by only first year med students. All the best technology in the world will not save lives without the critical knowledge of the doctor. In the same way, all the best traction systems on a car are useless without proper tires.
