Wheel alignment and wheel balancing are different service but are both very important part of tyre maintenance. It is needed to enhance the life and performance of your tires.

Wheel alignment sometimes called as ‘’front end alignment”, is the process in which the technician will adjust the angle of your car’s wheel to the position according to the manufacturer’s recommended specification. The purpose of this adjustment is to reduce tyre wear and keep your steering wheel and tyres in the straight position.

Wheel balancing is done by taking the wheel off the vehicle and placing it on a wheel balancing machine. The technician will use a calibrated spin balancer and usually test both static (none moving) and dynamic (moving) wheel balance. The procedure usually done once every 5-6,000 miles or every 6 months and during when a new tire gets fitted it must be rebalanced. If you feel vibration in the steering wheel, the floorboard or your seat it is the time that may need a tyre balancing done.

There is no exact time to change your tyre. Your car performance depends on your tyre so you have to be watchful of the condition of your tyre for your own safety. There are many signs to determine that you need a new tyre. Keep an eye check on the thread if the tyre is visibly worn out, have cracks on the sidewall then it’s time to bring them to the repair shop and change as soon as possible. With everyday used, your tyre become flatter overtime and it will reduce control and can be dangerous on the road. It is recommended to change your tyre once they reach to 3mm in depth to stay safe. Another signs to consider that the tyre needs to be replaced is the unusual vibration or sound you hear while driving, you will probably know the changes if there is an excessive vibration or hearing a buzz then you decide to change your tyre.

As per UAE law it is required to change your tyre once every 5 years from the date of manufacture even if they appear to be in a usable condition and haven’t been worn out. But as long as you were able to used tyre within 5 years from the date of production it’s okay to buy with any date of manufacture. However the tyre can last longer depending on proper maintenance, you’re driving habit and the weather condition.

Tyre size
Each tyre has size designation that read as these; 275/40/R20 106Y 275 = Tyre width in millimetre (mm), measure from sidewall to sidewall. 40 = Height-to-width ratio in percent. It is the sidewall height of the tyre. R = Radial construction 20 = Rim diameter in inches (code) 106 = Load index Y= Speed index Tyre sizes which have been approved for vehicle are specified in the vehicles documents. Also your tyre must comply with the vehicle’s requirements in terms of load and speed as well as other recommended specification.

 

Load Index
Load index represents the tyre load carrying limit. The maximum load capacity of a passenger car type is indicated by its Load Index (LI). For this tyre size 275/40/R20 106Y – 106 is the load index- which indicates the tyre ability to carry approximately 615kg It is not suitable to replace your vehicle’s tyre with lower load index it must be the same or higher load index.

 

Speed Rating
Speed rating is a letter symbol represents maximum speed the tyre can handle at full load. The tyre maximum speed must be at least equivalent to that of vehicle. A tyre with V speed rating for example has a maximum of 240km/h or 150mph.

 

UTQG
Uniform Tyre Quality Grading or UTQG rating is made up of three components, Tread wear, Traction and Temperature. It is mandated by the National Highway Traffic Safety Administration, a branch of the United State Department of Transportation (DOT). Each tyre has different measurement so that the customer can understand well and help them choose in buying the right tyre. It is also marks in your tyre sidewall. The rating is from A= Superior, B= Good and C= Average. Ex: UTQG: 600A/B

 

Tread wear
A relative life expectancy or the durability of a tyre base on standard testing. A rating is based on a 100 tread wear control tire. For example, a 500 tread wear rating is expected to take 5X as longer to wear out. However these tread wear grade has no guarantee on the actual mileage of a tyre. The longevity may vary base on proper care and maintenance and your driving style.

 

Traction
Represents the wet braking capability of the tyre. Traction test procedure measure a tire’s coefficient of friction when it is tested on wet asphalt and concrete surfaces. Traction grades from highest to lowest are AA, A, B, and C. The top of the scale rating AA has the capability that could instantly stop on a wet pavement.

 

Temperature
The temperature grades, from highest to lowest are, A, B and C these represent tyre temperature stability at higher test speed and its resistance to heat.

 

Fuel Efficiency & Rolling Resistance
Whenever a tyre need contact with a road surface the energy apply in order the tyre to maintain movement at the consistent speed or to keep a tyre rolling. Depending on the tyre rolling resistance is how its fuel efficiency ranges. Rolling resistance measures how much of the energy that makes it to the tire is lost to friction on the road. The higher the friction the more energy will be needed to keep the tyre rolling as the engine works harder the more fuel being consumed. The tyre rated from A’ as the most fuel efficient and G’ as the least fuel efficient. The rated A’ tyre could save you enough petrol cost than other, but proper tyre pressure also can improved your gas mileage by 0.6% up to 3% in some cases.

 

Exterior Noise of the tyre
External noise grading indicates the tyres contribution to traffic noise and the environment. The unit grading used is in decibel (db).There are three ratings for the noise as indicated by sound waves, with one bar indicating the quietest tyre to three bars as the loudest rating. This is not the sound you hear inside the car but the external noise caused by your tyre.

 

Wet grip/ braking performance
The performance of the tyre on the wet road surface is important on choosing the right tyre. A tyre with superior wet grip has the capacity to stop quickly on wet and slippery road and benefits you on safety in whatever condition. The tyre rated from A-G, A- being the shortest braking distance on wet and G- being the longest breaking distance on wet.

 

Max inflation pressure
The recommended pressure for each tyre marks on the sidewall of the tyre; it can also be found in the owner’s manual or indicated on the vehicles itself. That number tells you the maximum pressure needed for your tire to carry its maximum load. Air pressure measurement should be done when tyres are cold completely after driving. The correct tire pressure can help save fuel, and reduce accident’s rate at the same time, to ensure safety. It is recommended to check your tyre regularly at least once a month or after a long drive. The standard unit measurement for air pressure is PSI or Pound per Square Inch.

 

TWI
Tread Wear Indicator. A number of small raised bars run across the main grooves. The bars have a height of 1.6mm and slowly worn out after a long wear and become level with the rest of the tread.

 

Date of Production (DOT)
The US department of transportation or DOT oversees tyre safety standards. The date of production of each tyre can be found also on your tyre sidewall markings. It is a combination of letters and numbers printed that indicates the place and the dates of tyres manufacture. The code may appear as this example DOT LMOF BXXF 2518; the letters represents the factory code followed by 4 numerical numbers which indicate the first 2 digits for the weeks and the last 2 digits for the year of production. This means that the tyre manufactured on the 25th weeks of the year 2018. In compliance with the Gulf Standards Organization regulation we only sell brand new tyres which come with the annual warranty period.

 

OE and OEM
OE means Original Equipment while OEM stands for Original Equipment Manufacturer. OE is the original parts of the vehicles fitted in the factory. OE tyres are developed for each vehicles model type according to manufacturer’s specification. Only OE approved tyres are fitted to a new vehicles.

1. Tire size
The most important thing that you have to identify before buying a tyre is your tyre size. Your tyre size information is in the owner manual or posted on the driver’s side doorjamb. If you also check your current tyre fitted on your car you will find out your tyre size marked on the side wall.

 

2. Weather condition
One factor to consider is the weather condition; the type of tyre you choose will depend on the climate you live in. Like here in UAE, although rain are rarely seen in most part of the region but still you might want getting tyre that provides good performance in wet and dry conditions. It is because season changes from hot to cold. During winter as the temperature fall down it will affect the tire pressure and it will lead to traction consequences. Summer tyre and all season tyres are just two of a kind that you will probably be contemplating for when choosing, however you must choose the right one that you needed the most.

 

3. Driving habit
Another one is your driving habit; consider the roads your travels normally take you. Let say you’re driving for mainly roads and highway for maximum safety; look for tyres that provide best and more reliable on breaking distance on both dry & wet roads. Each tyre has an individual grading for its grip so you might want to select the top of the scale Traction A rating. If you are always off to a long drive, you might consider choosing tyre that offer comfort both in terms of vibration and noise level, you can choose 68dB below as the quietest.

 

4. Manufacturer’s recommendation
Be sure to buy tyre that are appropriate based on your manufacturer’s recommended size, speed rating, load capacity and any important specifications such as proper tyre maintenance.
