Alloy wheels are automobile wheels that are made from aluminium/magnesium/chrome metals that serve as the base alloys. These alloy wheels differ from normal steel vehicle’s wheels, as they are lighter in weight. They also improve the cars’ performance by increasing their mileage.

Alloys are also known for their heat conducting property that surpasses the steel wheels .This improves the overall heat dissipation of the brakes, thus reducing the chance of brake failure in extreme driving conditions.

Alloy wheels cost more

These alloy wheels are also considered chic, as they are not hidden behind the hubcaps. Thus, they reduce the weight of the car. However, these alloy wheels are pricier than ordinary wheels, making them slightly less palatable for general consumers.

Magnesium alloy wheels are also referred to as mag wheels and are sometimes used on racing cars instead of the heavy steel or aluminium wheels as they give better weight reduction and acceleration. The wheels are formed in only one-step by hot forging from the magnesium alloys ZK60 and MA-14. The Russian variation of the ZK60 is used in this process. The disks made of cast magnesium are also used in dirt bike wheels. The weight of a typical magnesium automotive wheel is about eight-twelve kilograms.

Mag wheels are highly inflammable

Magnesium wheels may be lighter than aluminium alloys but are easily flammable and are banned in some arenas of motor sports in the United Kingdom due to occurrences of fires. These fires are very difficult to extinguish and are hazardous as they can become fatal for the driver. The fire initiates as and when the tyre is punctured and the wheel scrapes the rough road surface for a prolonged period. There are some variants of Magnesium alloy wheels available that may have low corrosion resistance.

Expensive and dangerous equals impractical

These hazardous features of Mag Wheels – along with them being expensive – make them impractical for usage in most common vehicles. Aluminium wheels are often popularly referred to as “mag wheels” and are preferred over the mag and chrome wheels.

Many wheel brands, including: Panther Wheel, American Racing Wheels, Motegi Racing Performance Wheels, Weld Racing, BBS, 5Zigen, Volk Racing and Konig, are known manufacturers of quality alloys. The aftermarket wheels have also been inundated with the vast incursion of reasonably priced chrome wheels from East Asia.

India is now investing in alloy wheels through Synergies Castings Ltd. and other companies, and as a result is emerging as a leading supplier of chrome wheels. They are able to manufacture products to a universal scale due to the availability of cheap but highly trained and experienced labour. One of the oldest aftermarket wheel companies dating back to 1956 is the American Racing, which owns Motegi Racing and Weld Racing among other famous brands.

A recent trend in the manufacturing industries involves joint venture partnerships being shaped between offshore firms, local importers and distributors. These partnerships have initiated a stern competition between the giants of manufacturing, thus leading them to do extensive R&D. This has left the market flooded with a vast collection of superior alloys to choose from, thereby benefiting the car users.

    Mag wheels are NOT highly inflammable. Magnesium and Aluminium will burn fiercely but usually only after the flash point temperature has been reached, approx. 1371 degrees Celcius.The car would need to be on fire.
    To say that they are highly inflammable implies that they can burn by being ignited with a match. This, of course, is not true.

    Correct Magnesium alloy wheels are NOT flammable. I have seen them burn during a crash where the gas tank poured gas on the tires, the tires ignited and after 10 minutes or so the wheel finally started to burn. It was easily put out with a fire hose. Once the gas and tire were extinguished the wheel stopped burning instantly. Friction with the ground will not cause a magnesium alloy wheel to start burning.

    Thanks for the effort you took to expand upon this topic so thoroughly.
    Tires are among the most important components of your car. They are the only components of your car to make contact with the surface of the road, so they alone transmit the energy produced by your car’s engine to the ground. They determine in large part the overall handling and performance of any motor vehicle. For all of these reasons, it is important that you are careful when shopping for a new set of tires. There are many tire options covering wide ranges of price, performance, and appearance.
