The offset of stock Silverado wheels is the distance between the wheels well and the mounting spot of tires. In addition, it is a measurement that identifies the appropriate fitting of wheels in the assembly and centerline. However, people move the offset of truck wheels with backspacing, but both are different phenomena.

What does offset mean when buying wheels?
When researching and shopping for new wheels, one of the most common factors discussed is wheel offset. Having the correct wheel offset will make or break your wheel and tire fitment. Wheel offset refers to how the wheels mount in your wheel wells, and as a result, how much space you have on either side of the wheel.

- Place the wheel on the ground with the back side facing up. ...
- Lay a straight edge ruler across the center of the tire. Position the straight edge so that it lays flat over the wheel.
- Measure from the floor to the bottom of the straight edge. ...
- Divide the measurement by 2 to find the center line. ...
What is offset on a wheel?
What is Wheel Offset? In short, offset is the distance from the center line of your wheel to the mounting pad. If the mounting pad is closer to the face of the wheel from the center line the wheel is a positive offset, if the mounting pad of the wheel is at the dead center of the center line the wheel is a zero offset and if the mounting pad ...
What Offset Does My Vehicle Require?
No vehicle has a set number that they require , every vehicle has a minimum and maximum offset tolerance they can use. It is very important that the wheels you choose are within that minimum and maximum offset range to prevent fitment issues.
How to measure backspacing on a wheel?
Measure your backspacing. With the wheel laying flat on its face measure the distance between the mounting pad of the wheel and the outer edge of the wheel barrel.
What is the difference between backspacing and offset?
If you skipped that section, the backspace of a wheel is the distance from the outer edge of the wheel to the mounting pad. While the offset of the wheel is the distance from the centerline of the wheel to the mounting pad.
How does offset affect fitment?
The easiest way to understand how the offset affects your fitment is, the higher the offset the closer the wheel is to your chassis and the lower the offset the further the wheel is from your chassis.
What tolerance do you need for wheels to stick out?
If you want the wheels to stick out the least or not stick out at all aim for options closer to your maximum tolerance of 12.
How to determine wheel flange size?
Determine your centerline, this is your wheels width divided by two being the dead center of your wheel. Measure your backspacing.
What is offset on a wheel?
The wheel offset is the distance between the wheel mounting surface and the centerline of the wheel. In other words, the mounting surface is where the lug holes are. The centerline is the center of the wheel. There are three different offset ranges:
What is the difference between positive and zero offset?
There are three different offset ranges: Positive: When the mounting surface is in front of the centerline and closer to the outside rim than the back part of the wheel. Zero: When the mounting surface is right where the centerline is; this gives your wheels a centered look.
What happens if you offset too much?
There are problems that come with too much positive or negative offset, the most common ones being poor handling and additional stress on the wheel bearings and suspension system. If your new wheels are wider than the original wheels, you have to factor in the backspacing with the offset. It’s important to keep the new offset within 5 millimeters within the old offset.
What Is Backspacing?
Backspacing is the distance between the wheel mounting surface and the back of the wheel. You need to get the wheel offset and backspacing measurements right in order to keep your car’s performance and handling optimal.
What is offset wheel?
Wheel offset represents the distance between the centerline of your wheel and the surface where it mounts to your hub. It’s important to install wheels with the right offset so that they don’t rub against your fenders, brake calipers, and / or suspension components.
Why Change Your Wheel Offset?
Rim offset is not something that should be changed or messed around with unless you’re going after a very specific result. There are many reasons why you’d want to go for negative, positive, or zero offset wheels.
What does it mean when a wheel has zero offset?
Rim offset can either be positive, negative, or zero. Here’s how the three types differ: To visualize this, look at a wheel from the top and picture an imaginary line that represents its inner mounting surface. Now, if this line is visibly in the center of the rim, it means that the wheel has zero offset.
What does a -10 offset wheel mean?
The same applies to negative offset wheels. -10 offset means that the mounting surface of your wheel is 10 mm away from the centerline, towards the inside. So if you switch from a zero offset wheel to a -10 offset wheel, it’ll pop out by 10 mm.
What are the downsides of positive offset wheels?
Clearance issues are the only major downside of positive offset wheels. If you have enough room in your wheel cavity, then you can enjoy the advantages of positive offset. If you’re low on space however, you might experience the following problems.
Why do car guys change their offset?
Car guys change their offset usually when they’re switching to a new set of wheels. It is done in order for a certain type of wheel to fit properly. The two main goals include: More stable handling. Better stance / wheel fitment.
How to measure wheel width?
Place the straight edge horizontally on the rim, and the ruler vertically in a way that they intersect. The vertical ruler will measure from the floor to the outer edge of the rim where the horizontal straight edge is placed. The measurement you get is the full width of the wheel. Let’s call it W.
