Quick Answer

Frequent Question What does 0 offset on wheels mean?

Offset refers to how your car’s or truck’s wheels and tires are mounted and sit in the wheel wells. Zero wheel offset is when the hub mounting surface is in line with the centerline of the wheel.

Will 0 offset wheels stick out?

Wheel Width

If you install a wheel that is 8.5 inches wide with a zero offset and a tire that is 295 mm (11.61 inches) wide, the 8.5 inch wheel would stick out 1/2 inch more than the 7.5 inch wheel while the edge of the 295 mm wide tire would stick out 15 mm (0.59 inches) more than the 265 mm wide tire did.

What is 0 mm offset?

Your wheel offset is the distance from where you mount your wheel to the wheel’s center. The centerline is the literal “center” of the width of your wheel. This centerline is also known as a 0 mm offset. That’s important to note because your wheel offset is always measured in millimeters.

What is the difference between offset and 0 offset?

​“0 Offset”: The hub mounting surface is even with the centerline of the wheel. “+ Offset”: The hub mounting surface is toward the front or wheel side of the wheel. Positive offset wheels are generally found on front wheel drive cars and newer rear drive cars.

How much offset is too much?

Tire rub is even worse, as it will very quickly rip up the inside sidewall of the tire, an area where the damage is very hard to detect until the tire blows out. This is why that ideally, you don’t want the new offset to be more than 5 millimeters away from the old offset in either direction.

Do positive offset wheels stick out?

Most of the truck wheels come with a positive offset. This means that the wheels are not necessarily sticking out. Now, you just have to adjust the offset to negative or less positive to see that the truck’s wheel stick out. Offset is usually measured in millimeters.

How far does a 0 offset stick out?

Well-Known Member. 0 offset is in the middle of the wheel so if you took a tape measure and stuck it in your current wheel to where you feel the back plate and measured out half the distance of the wheel you would be close.

Which offset sticks out more?

A simple way to understand offset, is the lower the offset, the more the wheel will stick out, likewise, the higher the offset, the more the wheel will tuck in. For example, and Honda Civic generally uses around a +40mm offset.

Which offset pushes wheel out?

You can see how a positive offset will tuck the assembly further under the fender, while a zero or negative offset pushes the wheel out towards or even past the fender.

How do I figure out wheel offset?

HOW TO MEASURE OFFSET

  1. Lay the wheel/tire assembly on the floor and place a straight edge across the tire.
  2. Measure the distance from the floor to the straight edge and divide by two.
  3. Measure the distance from the floor to the straight edge and divide by two.

Is 10mm offset a big difference?

10mm isn’t a huge amount. On some cars it makes little difference. Tough you say. But if you want exact fit…see if the dealer still make it right.

How do you tell the offset of a rim?

First – add 1″ to the rim width and then divide by 2 to find the wheels center line (you have to account for the wheel flange which is why you add 1″ to the rim width). Second – convert the offset which is in millimeters into inches (there is 25.4 mm in 1 inch so divide the offset by 25.4).

Do spacers add or subtract offset?

Yes, they change offset. If you have 40mm offset wheels, a 10mm spacer would make them 30mm. This why you should ALWAYS buy a higher numerical offset when you have any doubts. A 50mm offset can become a 45mm with spacers, but until someone invents an anti-matter spacer, it isn’t going to happen the other way around.

Does negative offset help with rubbing?

On these trucks, moving the wheel outboard almost always causes more rubbing. The exception is if you have a wide enough tire on the stock wheels, the tires can rub on the radius arms. To avoid rubbing, look at 20×9 wheels with +18 mm offset or perhaps 0 mm offset. Going negative is just going to make it worse.

Is lower offset better?

Looks: A smaller offset moves the wheels outward, so they have a tendency to fill out the wheel well better. Cars set up for show, more than performance will often choose a lower offset wheel, however, if the offset is too small the sidewall will rub the inside of the fender.

Will 10mm offset make a difference?

if you wheels are very into the wheel well, 10mm might make your car look better as the wheels will stick out a bit. The width of the wheels that you are buying is the key thing to bring into the equation. If they are the same width as yours, ideally limit your choices to those with an offset of at least +45(mm.)

What is 12mm wheel offset?

A wheel with a -12mm offset would have a hub mounting surface 12mm inside of the wheel centerline, or closer to the back side of the wheel lip. This type of wheel usually has a “deep” look as compared to a zero or positive offset wheel. Most all factory truck wheels are positive offset to one degree or another.

What is better negative or positive offset?

If your offset is too positive, you risk the inside of the tire hitting your suspension. To fix this, bring the offset down, so it’s closer to zero. This moves the tire out. If your offset is too negative, then the outside of the tire will rub on the car’s body and fenders.

How far out is offset?

Well-Known Member. Yup.. – 12 offset. Sticks out sbout an inch.

What is negative wheel offset?

Negative offset is when the hub mounting surface is toward the back or brake side of the wheels centerline. A negative offset wheel usually has a “deep lip” Zero offset The hub mounting surface is even with the centerline of the wheel.

How far will offset rims stick out?

That offset is about 13mm or 1/2″ less than stock, so that will cause the rim to stick out 1/2″ more, plus the rim is 1.5″ wider than stock, so you have to split it, causing the rim to stick out another 3/4″. So 1/2″ + 3/4″ is 1.25″ more than stock.

What does ET25 mean?

ET Wheel Number Explained.

This is a number stamped on the rear spokes or mounting face of an alloy wheel. The ET of a wheel is the measurement in mm of how far the wheel’s centre line is from its mounting face. An example of such a number would be an ET25 for the 3SDM 0.05 White alloy wheel.

What does 50mm offset mean?

So, if a wheel has an offset of 50mm, that means that the face where the wheel will bolt to the hub is 50 millimeters to the outer, curb side from the wheel’s centerline. Conversely, an offset of -50mm is the opposite, 50 millimeters to the inside of the centerline, yielding a deeper “dish” in the wheel.

What are the rims called that stick out?

Turns out, those rims are called “swangers.”

Is backspacing and offset the same thing?

Backspace is the distance from a wheel’s mounting surface to the back edge of the wheel in inches. By “back” we mean the brake side of the wheel. Offset measures the distance from the mounting surface of the wheel to the centerline of the wheel, and it is often indicated in millimeters.

Does wheel width affect offset?

If you’re using the same width as stock, all you need to pay attention to is the offset of the new wheel. If you are changing the width of the wheel, the offset equation changes completely and you need to reevaluate the offset.

Does negative offset move wheel out?

Negative offset wheels have the opposite effect moving the wheel and tire assembly out and away from the brakes, suspension, and body. Almost all aftermarket 4×4 wheels that are 9 inches wide or wider have a negative offset. They are typically wider than stock wheels to accommodate wider and larger diameter tires.
