I was wondering if u guys know if wheel specs are indicated anywhere on the wheel itself, specifically the offset?

Yea..i know.. im embarrassed to ask, but i wanna know cause i'm thinking of getting spacers for the rear, and i've forgotten the info.

 

Your original receipt, boxes or
Try looking on the inside of the wheel many are stamped w/et then a number.
If that does not work try the manufactures web page to see what offsets the sell that fit the one you have.
Then if all else fails you can measure it

Wheel width plus one inch divided in half = zero backspace/offset
measure distance from mounting surface to edge off wheel this is total backspace
Subtract the zero backspace from your measurement the difference = inches in offset + or -. (greater than zero offset = plus offset, less than zero backspace = minus offset)
Convert to metric and you have offset

Example

8 inch wide wheel
8 plus 1=9
9 divided in 1/2= 4.5= 0 offset
you measure 5.5inches from mounting surface to edge of wheel
5.5 is greater then 0 offset so its pos offset of 1 inch
5.5-4.5=1
1inch =25.4mm offset is @+ 25

 

If your front & rear wheels are the same width & offset (not staggered), then 15mm spacers on the rear is what you want. This assumes that your tires are all the same size, you're already dropped as much as you want, and that your fronts don't rub at all.

 

thanks guys! that was very helpful
