now I wonder what the backspacing and offset are on my wheels. I loked them up on ultras web site and they make one with 4.5 backspace and one with 5.5, I don't know which one i have. right now i am running 285/70/17's but i wanted to go 35" next and i don't know if they will clear. how do you measure backspacing?

Take a wheel off; put a 2x4 or something flat on the back of the wheel, from one edge of the rim to the other edge (make sure you do not touch the tires).
At the center, measure the distance between the edge of the 2x4 to where the wheel sits on the drum. The result is your backspace.

You can do this from the front while the wheel is on, if you follow the above procedure. Then subtracts the difference to your rim width. For this, you need just enough space between the wheel spokes to touch the drum.

Hope this helps.

Awesome! I knew they would. Definately get some pics up when you get the rest of the wheels.

I checked mine and they are the wrong backspacing I did go into les schwab and they said that when I get ready to go to 35's they would trade me for the new wheels with the right backspacing for a very reasonable price. so now i just need to use up the last of these 285's, that probably won't take to long.
