What offset should I get on my wheels?
Choosing the right wheel offset is crucial for both the performance and aesthetics of your vehicle. As the owner of Kevin's Autos, I have seen firsthand how the right offset can enhance handling, improve tire wear, and give your car that perfect stance. In this article, we will explore what wheel offset is, why it matters, and how to determine the best offset for your vehicle.
Understanding Wheel Offset
Wheel offset refers to the distance between the wheel's mounting surface and the centerline of the wheel. It is measured in millimeters and can be categorized into three types:
- Positive Offset: The mounting surface is located towards the front or wheel side of the centerline. This is common in modern vehicles and helps to keep the wheels tucked under the fenders.
- Negative Offset: The mounting surface is located towards the back or brake side of the centerline. This is often seen in vehicles designed for off-road use or those with a wider stance.
- Zero Offset: The mounting surface is aligned with the centerline of the wheel. This is less common but can be found in some custom applications.
Why Wheel Offset Matters
The offset of your wheels affects several aspects of your vehicle's performance and appearance:
- Handling: A proper offset can improve your vehicle's handling by ensuring that the tires maintain optimal contact with the road.
- Tire Wear: Incorrect offset can lead to uneven tire wear, which can shorten the lifespan of your tires.
- Aesthetics: The right offset can enhance the overall look of your vehicle, giving it a more aggressive stance or a cleaner appearance.
- Clearance: Offset affects the clearance between the wheel and suspension components, as well as the fender. Too much positive or negative offset can lead to rubbing issues.
Determining the Right Offset for Your Vehicle
To find the right offset for your wheels, consider the following steps:
- Consult Your Owner's Manual: Your vehicle's manual often provides specifications for wheel size and offset.
- Measure Your Current Wheels: If you're replacing wheels, measure the offset of your current wheels to maintain similar handling characteristics.
- Consider Your Vehicle's Use: If you plan to use your vehicle for off-roading, a negative offset may be beneficial. For street use, a positive offset is typically preferred.
- Seek Professional Advice: If you're unsure, consult with a professional at an auto service center like Kevin's Autos to help you choose the best offset for your needs.
Conclusion
Choosing the right wheel offset is essential for optimizing your vehicle's performance and appearance. By understanding the different types of offsets and considering your vehicle's specifications and intended use, you can make an informed decision.

Frequently Asked Questions
How do I determine what offset I need for wheels?
Place a solid, flat item, such as a board, across the wheel so that there's a flat surface touching both sides of the wheel. Then, using a ruler or tape measure, measure the distance from the mounting surface to the base of the object. Now you have your offset!
Is too much negative offset bad?
Too much negative offset risks putting too much abnormal weight on your suspension system. Imagine that you're holding a weight in each hand. The further you extend the weights away from your body, the more difficult it is to keep them up.

TIRE SIZE GUIDE - WHEEL WIDTH MINIMUM AND MAXIMUM
| TIRE SIZE | MINIMUM WHEEL WIDTH | MAXIMUM WHEEL WIDTH |
|---|---|---|
| 35X12.50R15 | 8.5" | 11" |
| 35X13.50R15 | 8.5" | 11" |
| 35X14.50R15 | 10" | 12" |
| 37X14.50R15 | 10" | 11" |
What is the rule for wheel offset?
A negative offset will push your wheel out, and a positive offset will tuck it under the fender. A positive offset means your wheel is mounted closer to the outside or roadside, which pushes it further under the guard.
What do people mean by 35s?
In general if someone says they have 35's, it basically measures close to but usually slightly less than 35 inches from top to bottom of the tire when fully inflated. It's real common on off road vehicles like Jeep Wranglers. Some tires give this number in the last 2 numbers on the tire size.
What wheel offset is best?
Simple answer is anywhere between 60mm and 20mm would be good, with optimal offset being closer to 60 than 20. At 20mm, and depending on the tire size, the tire will just start poking past the fender and cause some handling and clearance issues when turning.
What is a +20 offset?
If the back pad is in front of the wheel's centerline, towards the wheel's face, the offset is positive. So a wheel with the back pad 20mm in front of the centerline of the wheel, the offset becomes +20.
What does +35 offset mean on rims?
If the face is toward the outside, it has positive offset. Positive offsets can be used to clear big brakes. If the face is toward car, it has negative offset. Think deep dish wheels. +35 means the face of the wheel is 35mm from the centerline toward the outside.
What does a positive offset look like?
Positive Offset: The mounting surface is closer to the front (the outside edge) of the wheel. This means the wheel is tucked in more towards the body of the car. It's like tucking your feet under a chair when you sit down.
What offset will make wheels stick out?
Positive offset refers to a wheel in which the mounting flange is pushed closer toward the outer lip, resulting in a recessed, sunken-in appearance. Inversely, negative offset refers to the mounting flange positioned further inward from the wheel's centerline, thus prompting the wheel to protrude further from the body.
