The term alloy wheels is usually given to wheels 'cast' from a mixture of aluminum instead of steel, making the tires light weight even though they’re usually larger in size than the factory fitted steel wheels. Aluminum helps dissipate heat and small amounts of more rigid metals whose presence in the 'mix' provides rigidity and helps prevent cracks propagating.
1. Aesthetic value (beauty, elegance, and a sporty look)
2. A variety of designs to choose according to one's taste
3. Light weight (hence low unsprung weight) resulting in lower inertia being imparted to the springs while riding over a bump
4. Lighter rotational mass improves acceleration, braking, and fuel efficiency
5. Better road holding (tire remains in contact with the running surface longer)
6. Better braking (wheel hop under traction is reduced)
7. Longer tire life because of better heat dissipation (alloy wheels are better conductors of heat). Tires fitted on alloy wheels are on an average 10% cooler than the normal rims, particularly at high speeds. Cooler tires wear out more slowly
8. Reduced and even tire wear because alloy wheels are invariable and perfectly true
9. No corrosion or rust since special aluminum alloys are used
10. Perfectly round and balanced hence no wobbling even at high speed
11. Completely airtight hence perfectly suitable for modern tubeless tires
12. Enhanced cooling of disks and drums
13. Less prone to bending and deformations, hence improved balance retention
14. Superior rigidity improved cornering, lateral stability, better steering & handling
