The term alloy wheel is used to describe every non steel wheel, usually one-piece, manufactured using a single mould. They are usually made of aluminium or magnesium alloys. For alloy wheels made out of magnesium alloys, we often use the term
Alloy wheels are lighter and firmer than steel wheels which gives them better performance. Due to their many advantages, alloy wheels are becoming more popular with car manufacturers and are being mounted as original equipment on new cars. Nowadays, it is hard to imagine a high class or racing car that doesn't come with alloy wheels.
The Advantages of Alloy Wheels
- Since they are lighter, alloy wheels reduce unsuspended weight (the part of the car that is not supported with suspension, e.g. tyres, wheels, brakes etc.) and therefore they exhibit better behaviour while cornering. When the car becomes lighter, it can keep the same speed at a lower fuel consumption.
- Reduction of rotating weight improves acceleration, braking and fuel efficiency
- Better road handling because the tyres stay longer in contact with the road
- Better braking
- Longer tyre life span because of improved heat dissipation (alloy wheels are better heat conductors). Improved cooling of discs and drums. Tyres mounted on alloy wheels are on average 10% less warmer than on steel wheels, especially at higher speeds. Therefore, they prolong tyres’ life span because colder tyres wear out more slowly.
- Reduced tyre wear due to precise manufacturing and solid form of alloy wheels
- Since they are made of special aluminium alloy, there is no corrosion
- Alloy wheels are perfectly round and balanced, there is no shake even in high speed, and the ride is comfortable
- They fully retain air in tyres which is a perfect match for tubeless tyres
- Improved cooling of discs and drums
- They are less susceptible to bending and deformation due to better balance
- Increased strength improves cornering, lateral stability, handling and keeping direction
- Beauty, elegance and sporty look. Every car, regardless of it’s class, looks better with alloy wheels
- Wide range of different models offered by manufacturers to suit every taste
- Splendour and beauty of alloy wheels will make the car be noticed
Disadvantages of alloy wheels
- Alloy wheels are more expensive than steel wheels
- If they are damaged, cars performance gets reduced and fuel consumption increases
- Car insurance expenses are bigger because of the risk of them being stolen. Some insurance companies do not allow modifications to the car, and it is advised to check with them before making modifications
- Since they are lighter than steel ones, they are susceptible to bending, which is hard to repair
- Soft alloy wheels are susceptible to damage from bumps and scratches
