What Are the Popular Sizes For Alloy Wheels?

When it comes to wheels, there are a number of different sizes available. These can make a difference to your vehicle’s looks and performance.

Having the right alloy wheel size is important when you’re looking to get your hands on some new rims for your vehicle. This guide will help you understand the different measurements and sizing considerations that affect your wheel options.


alloy wheels wholesale are popular for many reasons, not least because they’re less expensive than steel, but also because they offer an aesthetic enhancement to your vehicle. They’re available in a range of different sizes and styles, so choosing the right ones for your car can be an important decision.

Diameter is a very important factor when selecting alloys for your car. This is why it’s important to understand the basics of alloy size measurement, and to find a wheel fitment specialist who can help you figure out the correct measurements for your vehicle.

There are several ways to measure the diameter of an alloy wheel, but the most common is by measuring from the opposite end of the rim. The same applies to the width. This is a crucial part of the process, as it’s possible to get a wheel that’s too wide for your car.

If you’re looking for a way to find the best wheel for your car, consider using the PCD (pitch circle diameter) method. This is the point in the centre of the mounting hole that’s crucial for fitting certain types of alloy wheels.

Getting the wrong diameter for your wheels can result in a poor fit and a compromised driving experience. If you’re buying new alloys, make sure to ask the seller for this important information, and consult a wheel fitment specialist before purchasing.

The offset of an alloy wheel is one of the most important measures to look at. This is because it allows you to get the perfect fit for your vehicle. The offset is a measurement of how far the mounting face is from the center line of the wheel, and it can be either positive or negative.

A positive offset means that the mounting face is located at the front of the wheel, whereas a negative offset will have the mounting face behind the centre line. This can give your car a unique look, and it’s also very easy to customize a set of wheels with a negative offset.

In addition to the important measures of diameter and offset, you should also take into account the bolt fitment of your alloy wheels. This is an area that can be tricky to get the hang of, so it’s best to leave this to a professional.


Alloy wheels are a favourite among car owners looking to enhance the appearance or performance of their vehicles. However, it is important to get the right size wheels if you want them to fit correctly.

The most popular wheel sizes are 17-inch, 18-inch and 19-inch alloys, although a variety of other widths are available. These include 8-inch, 8.5-inch and 9-inch wide alloys.

Choosing the right width for your alloys is important because it will determine the way they look on your vehicle, as well as how easily they can get damaged. It is also important to consider the tire size and rim width.

When selecting a rim width, it is best to measure it with a set of Vernier calipers. These are designed to make precise measurements and have a scale embossed on them. The main outside-facing jaws can measure the rim’s outer width, while the smaller inward-facing jaws can measure the inner rim’s width.

Another important factor to consider when selecting a rim width is offset. Offset is the distance from the true centerline of the wheel to the mounting surface. Offset can be positive or negative.

Wheels with a positive offset have the mounting face located at the front of the center line of the wheel. These are commonly seen on cars with high ground clearance such as those with large off-road tires.

In contrast, wheels with a negative offset have the mounting face located at the rear of the center line of the wheel. These often sport aggressive fits with lots of concave or extreme dishes.

Besides the actual measurements, it is also important to understand what the ET numbers on the wheel mean. The ET is the measurement in millimetres of how far the wheel’s centre line is from its mounting face.

Finally, a wheel’s bolt fitment can be a crucial factor in whether it will suit your car or not. A wheel that is too tight or too loose will have a negative impact on your driving and may cause problems with tyres, suspension, brakes, and other parts of your vehicle.


Alloy wheels come in a variety of sizes and it is important to choose the right one for your vehicle. Choosing the wrong size can lead to problems such as rubbing on the bodywork or suspension components.

The most common wheel sizes are 15, 16, and 17 inch. However, you should also consider buying a larger alloy wheel if it suits your driving needs and preferences.

Many modern vehicles now feature alloy wheels as standard and are available on most base or lower spec trims, while steel wheels can often be found on higher spec models. The main difference between alloy and steel wheels is the type of material used to manufacture them – aluminium or magnesium.

Both materials are lighter than steel, which helps improve fuel efficiency and reduces cabin noise and vibration. They also provide better handling and improved road grip, which makes them perfect for sports cars and other performance vehicles.

Alloy wheels are more resilient than steel wheels and are typically more affordable. They are also easier to repair if damaged or scratched.

When you’re buying a new set of alloy wheels, it is vital to take into account the offset and backspacing measurements. These measurements dictate the position of your new wheel and tire package, which can affect how your car handles and looks.

Getting the offset and backspacing right is key to getting a wheel and tire package that fits well, provides good load capacity and gives you the looks and handling that you’re looking for. Using a wheel and tire professional can help ensure that you’re getting the correct measurements for your car.

The wheel offset is a measurement from the mounting surface of your new wheel to the centreline of your wheel. This can either be positive or negative, depending on where the hub-mounting face is placed.

A low wheel offset will push the new wheel inwards and can cause rubbing between your tyre and bodywork. This can damage your tyres, and can even cause serious bodywork damage if it’s too high.

Keeping your wheel and tire package within the recommended offset range can help prevent these issues from occurring, as well as give you a safer, more enjoyable ride. In addition, getting the measurements right means that your tyres and wheel stay within their load capacity, which can help you save money on your maintenance and insurance costs.

Bolt Fitment

Alloy wheels come in all shapes and sizes, so it’s important to get the right fitment. The size of the wheel isn’t just a matter of appearance; it also influences the weight of the tyres and the performance of your car.

When choosing alloy wheels, it’s also crucial to understand the bolt fitment. This is the number of lugs (also called bolt holes) on the wheels and their spacing.

There are 17 different 4- and 5-lug bolt patterns in use today, plus trucks and SUVs commonly use 6- or 8-lug wheels. The most popular is 5 x 4.5, which is the preferred size for passenger cars and light-duty trailers.

In addition to the lug pattern, wheel manufacturers often specify the number of bolts in a set as well. This is referred to as the wheel PCD, or Pitch Circle Diameter, and it’s measured in millimetres.

Ideally, your wheel PCD should match the one that came standard with your vehicle. If the wheels you choose have a different PCD to the standard ones, they won’t fit and could damage your car.

Another factor that can cause problems is the centre bore of the wheel. If the centre bore is not the same size as the hub lip, it won’t seat properly onto the vehicle. This can lead to vibration that is felt through the steering wheel and can in some cases cause the bolts or nuts holding the wheel in place to work loose.

To solve this problem, a number of adapters are available in the market that can convert your existing wheel hub pattern to the correct one for your new wheels. These can be either single or two-piece options.

They feature a base that’s made to fit the existing wheel hub and a hat on the other side that features studs in the same bolt pattern as your alloys. These can be bolted on with countersunk screws and are a quick and easy way to ensure that your new wheels will fit without any hassles.

Alloy wheels are generally a more durable option than steel wheels, but they’re still susceptible to damage from rough terrain. This can cause dents and imbalances that affect the performance of your wheels. A professional alloy wheel repair service can restore the look of your wheels and keep them performing as they should.
