Determining Wheel Backspacing/Offset Question

[snowbrdr033]

Is there any way to know/figure out what backspacing/offset I have on my wheels without knowing the model?
I know the guy before me put on 20" Enkei wheels that are fairly deep and are fairly wide when looking at the truck head-on. I've also got a set of spiders for down the road with lift/tires, but don't know if it's worth keeping them around or not since I've already got a pretty wide stance.

Thanks for any help....

If you have the Enkei RT6 in 20x9 its most likely a 12mm offset. Enkei only lists one offset for the 20x9 wheels.

Thanks for the link. Would this information still be applicable even if the wheels are 5+/- years old? Not sure if it stays consistent or not.....

well you could always take the wheel off and the offsets are usually stamped either on the spokes or on the hub.
