Thread: Rim offset DII

Hey Baz,
if no one knows/ replies take your spare off and measure it.
its the distance from the back of the rim to the face where the
rim bolts to the axle.

is yours a D2?? if it isnt then we got a problem ops:

Phil

Discowhite, that is the backspacing, not the offset.

Backspacing is the distance from the hub to the back of the rim. This determines with how far the tire reaches into the wheelwell. If you get wide wheels and keep stock offset, the wheel will increase backspace toward the inside.

Offset is the measurement of the wheel's centerline in relationship to your hub flange. Zero offset puts the hub flange at the center of the rim. Negative offset moves the rim out away from the vehicle and causes more of the more the wheel to stick out from under the truck. Positive offset moves the tire and wheel toward the vehicle.

The offset for the D2 and RR P38 is all 57mm, on all rims, be they 16 or 18" and also 7 or 8" widths.

Thanks Simon thats what i'm after, and thanks Phil i've did the measure it was the offset i was after.

Baz.

couldnt find me drawing with all the relavant terms
so i took a guess, sorta close. ops:

thanks slunnie i will rember it now! 8)

So if the backspacing is smaller the offset is smaller
Ea 120mm backspacing = 57mm offset standard :!:
100mm backspacing = 37mm offset wider track :!:
150mm backspacing = 87mm offset narrower track :!:
Is this correct? :?:

Thats correct Kaistuff.

The other implication when doing the maths, is that the measurement is taken from the back of the rim in a backspace measurement, not the outer mount for the tyre bead, so a 16x7" rim may actually measure 8".
