What are the advantages of alloy wheels?

• Aesthetic value ( beauty , elegance and a sporty look )
• A variety of designs to choose according to ones taste.
• Light weight ( hence low unsprung weight ) resulting in lower inertia being imparted to the springs while riding over a bump. 
• Lighter rotational mass improves acceleration , braking and fuel efficiency . 
• Better road holding ( tyre remains in contact with the running surface longer ). 
• Better braking ( wheel hop under traction is reduced ). 
• Longer tyre life because of better heat dissipation (alloy wheels are better conductor of heat) . Tyres fitted on alloy wheels are on an average 10% cooler than the normal rims particularly at high speeds . Cooler tyres wear out more slowly. 
• Reduced and even tyre wear because alloy wheel is invariable and perfectly true. 
• No corrosion or rust since special aluminium alloys are used . 
• Perfectly round and balanced hence no wobbling even at high speed. 
• Completely air tight hence perfectly suitable for modern tubeless tyres. 
• Enhanced cooling of disks and drums . 
• Less prone to bending and deformations , hence improved balance retention . 
• Superior rigidity improves cornering , lateral stability , better steering & handling .
