Customisation You can choose the alloy wheel design and size as per your liking. Steel wheels come with pretty much a standard design. There's not much scope for personalisation. Application Suitable for high-end and sports cars. Suitable for entry-level cars.Modern-day cars come with factory-fitted alloy wheels. But why are they so popular and look so flashy? To understand it, let’s get into more details in the points below.
Alloy wheels are made out of a mixture of metals.
Car alloy wheels are manufactured using a mixture of two metals: aluminium and magnesium.
They are generally manufactured by casting or forging methods.
The manufacturing method allows for the complex design of alloy wheels.
With unique designs, alloy wheels often add to the sporty quotient of the car.
Here are some of the advantages of alloy wheels.
Lightweight: As mentioned earlier, alloy wheels are lighter than steel wheels, thanks to the complex manufacturing process. The weight reduction helps in better handling, increased fuel economy and initial acceleration. Alloy wheels also aid in enhanced tyre life due to better heat dissipation.
Performance: Alloy wheels are light in weight. Hence, they transmit less weight to the suspension system. It results in improved road grip and handling. One can also experience slightly improved cornering and steering in a car equipped with alloy wheels.
Aesthetics: One of the main pros of alloy wheels is their design. They look premium and sporty. Nowadays, even the mid-range hatchbacks and sedans also get alloy wheels to enhance the looks. Apart from the performance, they are also pleasing to the eyes.
Rust-resistant: One of the main advantages of the alloy material is that it is corrosion and rust-resistant. So, alloy wheels can last longer and retain their shine. It is significant for people residing in coastal areas where surface corrosion is a common phenomenon.
Alloy wheels are all shiny and look good, but they also have their set of disadvantages.
Expensive: Alloy wheels are heavy on the pocket. They can significantly bump the car’s price. That’s the reason why entry-level vehicles do not come with alloy wheels. The high pricing is due to the metals used and the complex process involved in manufacturing.
Durability: Alloy wheels look good, but they are not as strong as steel wheels. They can crack or bend upon impact. Driving on cracked alloy wheels can be dangerous as the wheel may disintegrate due to the forces.
Complex repair work: Alloy wheels are not as easy to repair as steel wheels. The process is complex, time-consuming and expensive. Removing a bend or sealing a crack can cost you dearly and also takes a lot of time.
Steel wheels are often found on entry-level vehicles and older cars. They don't look great, but they are light on the pocket and serve the purpose very well. Below are more details of steel wheels.
As the name suggests, steel wheels are made out of steel or stamped steel.
Due to the material and construction, steel wheels are more robust than alloy wheels.
Steel wheels do not crack on impact or damage that easily due to the regular wear and tear.
Due to their durability, steel wheels are used in off-road SUVs, cars and even heavy vehicles such as trucks and buses.
Here are some of the pros of steel wheels.
Affordability: Alloy wheels cost way less than alloy wheels. It’s mainly because of the material used and the simple manufacturing process. That’s why manufacturers use alloy wheels on entry-level models. They reduce the overall price of the vehicle.
Durability: Steel wheels are stronger than alloy wheels. The chances of cracking upon impact are very low. Worst case, they may bend, which can be easily repaired. That’s why you will see steel wheels on hardcore off-road SUVs because they can take the beating of rough terrains.
Easy to repair: Repairing steel wheels is easy and does not cost much. Removing a dent or bend on a steel wheel requires nothing more than hammering. The process is quick, inexpensive and straightforward.
Steel wheels are practical, affordable and easy to maintain. But they have their share of disadvantages that are listed below.
Weight: Steel wheels are heavy, and it adds to the weight of the vehicle. The weight is transmitted to the suspension, and it affects the handling of the car. It also has an impact on acceleration and fuel consumption. The more the weight, the more fuel is required to propel the vehicle.
Rusting: Steel wheels are prone to corrosion and rusting, especially in humid environments. However, with painting techniques such as powder-coating, the steel wheel maintains its shine for some time. But they are not entirely safe from corrosion.
Aesthetics: Looks can be subjective, but you never see steel wheels on luxury or sports cars. They look too simple and do not appeal to the buyers. Nowadays, manufacturers offer different alloy wheel designs to enhance the appeal of the vehicle. In that regard, steel wheels look very basic and outdated.

Both the alloy wheels and steel wheels serve the same purpose, but the appearance and construction are different. The former is aesthetically pleasing but expensive, whereas the latter is inexpensive and practical. If you are looking for an affordable option, steel wheels are the best. They don’t cost much, are durable and easy to repair if things go wrong. But you may have to compromise on looks.
Alloy wheels are best suited for premium cars. So, if there are no budget constraints, you can go for alloy wheels. They are aesthetically pleasing, come in various designs, and have an impact on the handling and fuel efficiency of the vehicle. So, the choice depends on what you are expecting from your set of four wheels.
Let's look at some of the most commonly asked questions related to alloy wheels vs normal wheels.
Can I use alloy wheels for off-roading in my SUV?Yes, you can use alloy wheels for off-roading. However, you have to be cautious with your manoeuvres as alloy wheels can crack and deform under impact. They are sturdy enough but still not as strong as steel wheels. So, be careful when you tackle off-road terrains with alloy wheels.
Do alloy wheels affect the fuel efficiency of my car?Yes, alloy wheels have an impact on the fuel economy of the car. Since they are lighter than steel wheels, it may enhance the fuel economy to a certain extent. It all depends on the weight of the alloy wheels.
Do alloy wheels affect my car insurance?If the alloy wheels are factory-fitted, you need not worry about their implications on car insurance. But if you modify your car with aftermarket alloy wheels, you may have to inform your insurer about the modification. It helps to avoid any chances of claim rejection.
Can I change the design of the alloy wheels?There are several options in the market when it comes to alloy wheel designs. You can choose a design of your liking and change the existing alloy wheels.

When comparing Forged Steel Wheels and Cast Iron Wheels, each has advantages and disadvantages, which we’ll cover in this blog. One thing to note when comparing these two types of wheels is the manufacturing processes each undergoes, which affect costs, bonding ability, and strength.
Forged Steel Wheels, as the name implies, are manufactured in a forging operation. Forging is the term for shaping metal by using localized compressive forces. Forging can be done in a cold operation or a hot operation. For industrial wheels, a hot forging operation is used.
After the weight of the part is determined, a slug of steel round of appropriate diameter is cut and pre-heated to red hot. The steel is then drop forged, shaping the slug through repetitive impacts. The flash is sheared before the steel can cool. The part is then placed on a conveyor for a slow cooling process.
PROS AND CONS OF FORGED STEEL WHEELS INCLUDE:
Can support 30% greater loads than Grey Iron
Are more costly to the machine than the final dimensions
It is not a good bonding surface due to the density of the molecular structure
Excellent for applications with a significant risk of shock loading
It can be heat-treated to increase hardness and is easy to weld
Generally, it is 30-50% more expensive than a grey iron wheel.
Cast Iron Wheels are manufactured by melting pig iron while adding substantial quantities of scrap iron and steel scrap. Undesirable contaminants (e.g., phosphorus and sulfur) are removed at various steps that affect the material’s overall strength.
The melting process is done in a blast furnace known as a cupola or electric induction furnace. The material is wholly liquefied and then carefully poured into a sand mold. The casting is then removed from the sand mold, and final cooling occurs. The final grade of the grey iron is determined by the absolute tensile strength (Grade 30 is 30,000 lbs. tensile strength).
The microscopic structure of the two materials is significantly different and impacts the overall strength of the material/product. During the forging process, the molecular structure is in alignment and never disrupted during the forging process. Hence, the power in the virgin material is never lost. However, the original design needs to be maintained in casting, and a new facility with very little continuity is created, resulting in an insignificant reduction in strength.
PROS AND CONS OF CAST IRON WHEELS INCLUDE:
Can support a significant amount of weight
Machine very easily
Make an excellent bonding surface for a urethane tire
Cannot withstand shocking loading without risk of cracking or failing
Do not make suitable welding surfaces
Cannot be heat treated to change hardness
Considered a cheap alternative in an industrial application.
When choosing between a Forged Steel Wheel and a Cast Iron Wheel, there are many factors to consider. However, getting the correct wheel the first time will minimize long-term costs by reducing downtime and maintenance costs.
