What is a high positive offset wheel?
Wheel Offset and Backspacing Explained
- Zero wheel offset is when the hub mounting surface is in line with the centerline of the wheel.
- Positive wheel offset is when the hub mounting surface is in front (more toward the street side) of the centerline of the wheel. ...
- Negative offset is when the hub mounting surface is behind the wheel centerline. ...
How does wheel offset affect handling?
- Wheel diameter – A small rear wheel will increase the trail and rake while a smaller front wheel will reduce the trail and rake
- Triple trees/aftermarket yokes – These products will recalibrate the offset to then adjust the trail without impacting the rake
- Rear suspension – Lowering the rear suspension will increase the trail and rake
Is positive offset in or out?
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 does a Offset wheel stick out?
So if you put a +15mm offset wheel on the car, the wheel is likely to stick out about 1 inch. If you've ever noticed a lifted truck or a low rider with wheels sticking out, its because the offset of the rim is very low and in many cases so low that they are negative offsets.
Does negative offset on rims stick out or in?
A negative offset gives an inset or deep-dish look: -44 is deeper than -12. The wheel will also stick out from the truck. Keep in mind that some states require fender flares to cover the width of the wheel and tire.
Does positive offset push the wheel in or out?
In contrast, too much positive offset is a danger, as it will push the wheel farther in toward the suspension. Here's an extreme example: If you have to go from a 45 mm offset to a 20 mm, the wheels will protrude from the sides of the car.

5 millimetersEven if the tire and wheel have enough clearance, the wrong offset can decrease vehicle stability. Generally, with new wheels, you don't want the new offset to be more than 5 millimeters different from the old offset.
How much offset is 2 inches?
about 50 millimetersCalculate the offset. Then, subtract that number from the backspacing. For example, if the width I'd measured is 8 inches, my wheel centerline should be at 4 inches. Then, if my backspacing is 6 inches, 6 inches minus 4 inches is 2 inches. The offset is 2 inches, or about 50 millimeters.
Is negative offset better for off road?
By installing negative offset rims, you will push the wheel outwards and away from the suspension. Negative offset will also give a wider wheel track which can make your vehicle slightly more stable.
Does negative offset affect handling?
Regardless though, offset does do more than just fill or not fill the fenders-it affects handling, steering, traction, even the service life of otherwise unbreakable suspension components like knuckle assemblies.
