Offset question

[spindrift]

I'm running a BFG AT T/A KO (285/75 16) on stock (16x7) wheels. I believe the stocker wheel has a negative 0.25" offset. I'm planning to buy a set of
BFG AT T/A KO (285/65 18) and put them on a 18x9 wheel. I'm looking at two different wheels for the tire. One has a 5" backspace with a 0 offset and the other has a 5.47" backspace with a negative 12mm (0.47") offset. The Wheel Pros website says that both wheels will work on my Excursion. Obviously, both wheels are differeent than my OEM wheel. Any sense as to how much, if any, these two different wheels will look on the truck?

your stock wheels have 0 offset or 4" back space. and with the 99-04 trucks a 4.5" back space is perfect. and i pretty sure anything over a 5" back space will rub the leaf spring

Somewhat correct. The zero offest for the 99-04 trucks is 0 offset. You really don't want to go wider than a 295 with a rim width of 9" or more. The average rim in a 18 will be 18x9. You can go with a -12 offset if you have a leveling kit and are willing to trim the lower plastic valance. On my 01 excursion I did a 18x9 0 offset with a 325/60/18. The tire would rub on the leaf spring because the tires was so wide.

Just remember that the offset and back spacing is to prevent the tire from hitting anything on the suspension/body. If I were you I would purchase everything from a tire shop and have them mount them up and put them on the truck. Then you can take them through their travel and see what it looks like at least at static. When you begin working the suspension, say off-road, then those factors could change, so try to envision what thay may do to the clearances. That was how I purchased boots for a couple of 4x4's that I had in the past. Thank goodness I never had any issues due to that procedure. For what it's worth.

100% what fourfoeverfour just said. I work for a rim shop and try to give as much info as I can. I don't believe in buying wheels online. Support your local shop.
