wheel offsets and backspacing...


Recommended Posts

wierd...i'd think a 0 offset since it's in the middle...but good to know...thanks!

 

It's not in the middle since an 8" rim is 8" from inside to inside, where the tire mounts. But overall width is 9" when you include the thicknesses of the mounting lip (outside to outside).

 

(8"+1")/2 = 4.5 inches, this is the centerline of the wheel (going from the outside). It it was zero offset, then the backspace would be 4.5 inches.

 

Since they are -12 offset, the mounting face is inward 12mm (~1/2") from the centerline. That is how it is 4" backspacing.

 

I hope this helped...

Holy ****! That site you made is AWESOME Chris.

 

I'm going to have to do some serious reading tonight...Thanks! :icon14:

 

Thanks! I spent a ton of time compiling the specifications sheet, but got burned out on it and haven't really analyzed the data much. I think my favorite one was the understanding horsepower bit where I actually finally realized the value of horsepower under the curve and how it relates to displacement. :)
