So I bought a '17 F1fiddy and I want new wheels. The 20x9 wheels I found are 15mm offset, or I can get 20x10 with a -25mm offset. I absolutely love the look of this truck, which has 20x9 wheels with a -12mm offset. If I get the 20x9 (15mm offset) how will that affect the look? Will they be sunk into the wheelwell more, or will they be sticking out? If I get the 1" wider 20x10 with the -25mm offset, how will the wheels sit then? This is the look I want....
Picture looking over top of a rim. Say it is 10” wide. The centre line of that rim would be 5” correct?that centre line is considered 0 offset. when you move the centre line(which is the mounting point or surface to the hub)closer to the vehicle,it pushes the rim farther away from the vehicle essentially creating negative offset. So moving the mounting surface say 1” toward the vehicle will give it -25mil offset.
Hope that helps. Just google offset and how it works. It’ll show you diagrams which might help illustrate to you how it works.
Yeah, you need to look at that calculator and see how the numbers move the wheel inward and outward.
This site will compare offsets and visually show you the differences. https://www.willtheyfit.com
On a 9" wide wheel, the difference between -12 and +15 would pull the wheel inward over an inch (+15 is inward). Depending on tire size, that's probably not going to work for you.
A -25 10" wheel puts the wheel an inch further outward than the 9" -12.
Wheel offset confusion. Clarify please?
