How do I know my wheel fitment?

Vlada June 06 2022

When it comes to buying new wheels, one of the most important considerations is fitment. You need to make sure that the wheels you're interested in will actually fit your car. But how do you know what will fit and what won't?

What does fitment mean on wheels?

A wheel's “fitment” indicates how well the wheel will fit within a wheel well or beneath fenders. It's critical to be sure that the wheel and tire package you're buying both looks good and performs correctly. Without the proper fitment, a wheel and tire combination can rub against suspension components or bodywork, which can create all sorts of problems.

How to find wheel fitment?

There are a few things you need to take into account when determining wheel fitment. First, you need to know the size of your current wheels. This is important because you need to make sure that any new wheels you're considering are compatible with your car's existing suspension and brake setup.

You also need to know the offset of your current wheels. The offset is the distance between the wheel's centerline and the plane of the wheel's mounting surface. A wheel with a higher offset will sit further away from the car's body, while a wheel with a lower offset will sit closer to the body.

Finally, you need to know the bolt pattern of your current wheels. The bolt pattern is the number of lug nuts on the wheel and the distance between them. This is important because you need to make sure that any new wheels you're considering have the same bolt pattern as your current wheels.

Once you have all of this information, you can start looking at different wheel options to see what will fit your car. Keep in mind that some wheels may require spacers or other modifications to fit properly, so it's always a good idea to consult with a professional before making any final decisions.

With these tips in mind, you should be well on your way to finding the perfect set of wheels for your car. Just remember to take your time and do your research to ensure that you're getting the best possible fitment for your vehicle.

What wheel bolt pattern do I have?

The first figure indicates the number of bolt holes on the wheel. The second number is the diameter of an imaginary circle encompassing the holes. A wheel with a 5-100mm bolt pattern, for example, has five lug openings equally spaced around a 100mm-diameter circle.

How to measure wheel offset?

The easiest way to measure wheel offset is to take a look at the backside of the wheel. If the mounting surface of the wheel is closer to the outside edge of the wheel, then it has a positive offset. If the mounting surface is closer to the inside edge of the wheel, then it has a negative offset.

Most aftermarket wheels have a positive offset, which means that they sit further away from the car's body. This is because a positive offset helps to improve tire clearance and prevent the wheel from rubbing against suspension components or bodywork.

However, it's important to note that a wheel with too much positive offset can cause problems as well. A wheel with too much positive offset will sit too far away from the car's body, which can cause tire rub and other problems.

Conclusion

Fitment is an important consideration when buying new wheels. Be sure to take the time to find the right fitment for your car to avoid any problems down the road. And if you're ever unsure about anything, be sure to consult with a professional before making any final decisions.
