What Size Wheels Fit My Car?

Changing the size of the wheels on your car needs to be undertaken with care, as it’s necessary to stay within a size parameter appropriate for the car’s range. While you can go bigger and smaller, it’s vital to remain in a similar rolling radius to that which the car has fitted as standard. There are multiple reasons for this, which we’ll discuss in a moment.

What to consider when sizing a wheel

There are many aspects to take into account when sizing a wheel. These include:

Pitch Circle Diameter (PCD): This is the measurement of the bolt holes on the standard wheels that the car was originally fitted with

Wheel offset: Refers to how far out or how far under the wheel will sit from the wheel arch

Wheel diameter: The size of the wheel itself

Wheel width: Quite simply, how wide the wheel is

Wheel load capability: How much weight the wheel is capable of bearing

Center bore: The hole drilled in the center of the back of the wheel

Fitting kit: The wheel bolts, nuts, and spigot rings


These elements all need to be known if you’re considering changing the size of your car’s wheels. So let’s discuss the most important points when it comes to altering your car’s wheel size. 

Increasing and decreasing wheel size

There’s no denying that bigging up the rims is an awesome upgrade, but it needs to be done with care. The rolling radius needs to remain fairly similar. This means not going too big. If you do so, not only do you run the risk of reducing vehicle handling, but your speedo will be out of kilter and give a falsely lower reading. The car will also sit higher unless you lower the suspension.

If you want to go smaller, and there are reasons to do so, you must be aware that the car will sit closer to the road. This can lead to ground clearance issues. However, one of the biggest advantages of going down a wheel size is that you can use a higher profile tire, and therefore benefit from better ride comfort. Just be aware that you’ll also need to take into account the brake clearance, should you go down a size.

Quite simply, unless you’re experienced in changing the size of wheels on your car, it’s best to take expert advice before doing so.

Are OEM wheels the same as factory wheels?

Factory Wheels: are they worth it? 

OEM wheels are a popular choice when seeking new rims for your vehicle. OEMs are parts that are made with the backing of a manufacturer but are produced by an external source. In other words, if you were to purchase an OEM wheel for a BMW, it would be produced to the exact spec as that made by BMW themselves.

Factory wheels, sometimes called factory replica wheels, are also built to match these wheels, but will not be produced in conjunction with the main dealer. The two terms are often, incorrectly, used interchangeably. Only OEM wheels are guaranteed to be exactly as per the manufacturer item, both in physical appearance and in levels of safety. In many cases, high-quality OEM wheels are of an even higher standard than the original.
