Whats my backspacing?

Hey so i am just wondering what my back spacing would be. I am running stock 16" off road rims and 1.25" spidertraxs?? Any input would help thanks!!

And whats my offset?

 

??? No one knows?

 

i believe stock is 5.5. so minus 1.25 = 4.25

 

Would my offset stay the same then. I believe the stock ones are 0 offset?

I'm a nueb with the whole wheel setup thing.

 

The offset and backspacing of the wheel itsself doesn't really change. It's more like the "apparent offset" or "apparent backspacing".

Here's a handy chart that converts backspacing to offset. (1/3rd down the page)

With the spidertrax pushing your 7"(?) width rims out to 4.25" BS, your offset would be +6mm.

If the stock wheels are 7" wide and 5.5" BS, they would be +38 mm offset.

 

^^^ thanks much apreciated

 

No problem. Let me know if I can help further.

 

I am just trying to figure out if i can run a 6" lift with my stock rims( and spidertraxs) I am thinking its gonna work.
