Backspacing and Fitment questions...

[Aries]

ok, I want to run an 8 inch wide 15 inch tall wheel in the back.Gonna be putting the new Micket Thompson 27x10.5x15 ET Street on it. Now, the wheel has a backspacing of 5.5 inches...

Is that neough backspacing to fit?

[Aries]

anyone wanna help me out here?

augh, I hate "backspacing"..lemme convert it to offset here:

5.5 inches=139.7mm8 inches=203.2mmso139.7mm= offset+ 203.2mm/2

139.7=offset+ 101.6

offset=38.1mm

on an 8" wheel that will fit in the back, yes. (on an s14 anyway)-chet

So a 7" wide rim with 2.75" backspacing has a 6.35 mm offset?

I'm referring to these rims....which actually are 7.5" overall width.

That looks like 4 3/4 inch backspacing to me

[lessthanjakejohn]

backspacing = offsett + rimwidth/2

3.75 inches = offset + 7 inches/2

95.25 mm = offset + 177.8mm / 2

95.25 = offsett + 177.8/2

95.25 = offsett + 88.9

6.35 = offset

looks good tome...

That's a good site...Thanks for picking up on my mistake... 4.75" yields a +19 mm offset--more attractive than a +6mm

Man I want those wheels!
