I'm new to the forum and was wondering if anyone could explain offset and backspacing when it comes to aftermarket wheels & also I've got an 06 SCrew 5.4L XLT and was looking to level it out I've decided on the hell bent steel 3" kit and was wondering what would be a good A/T tire to go on aftermarket 17" rims

Here's what I've got to work with

HBS makes a good leveling kit but I would stick with a 2" or 2.5". As for a good AT tire, I like the Nitto Terra Grappler.

I think the factory BS is around 5" or5.75" not positive but, try to stick with the closest to factory BS as possible to keep the tire from sticking out the wheel well. As for a tire the terra grappler is a nice tire.

What will happen if I go with a different backspacing or offset than the factory wheel

stock is 5.71... if you choose more or less backspacing your tire will either stick out more or under the wheel well more...just remember ...depending on your tire size this could cause rubbing problems and something else to consider is your brake caliper clearance.

Thanks for the info. What would be a good A/T tire to go with?

I have mentioned something about this before on here and I will be glad to go over it again... There are pics of my '06 F-150 Lariat in my profile that you can look at to get a better idea of what I am talking about. I don't know much about the backspacing, but I can tell you about the offset and this is how I choose my rims/tires set-ups. My Lariat came stock with rims that were a +(positive)44mm offset and the rims I bought for the truck were a -12mm offset. How I determined what this is going to look like when I put them on my truck was I thought of the rim as if I was straddling it looking down at the tread of the tire. If the hub part of the rim is in the center of the tire that is a 0mm offset. As the hub moves closer to the face of the rim the number increases to the positive and the closer the hub is to the back of the rim the number becomes negative. Some people consider the backspacing, I don't fully understand it, but I do know it is directly related to the offset. But, like techrep said you do have to watch out for the clearance of the brake caliper. And I had Nitto Terra Grappler's on my Lariat and I was extremely happy with them. Hope this helps...

Thanks man that was a lot of help.

The distance from the inside face of the hub to the inside edge of the rim is what they are talking about with backspacing. As tech said the oem backspace is 5.71". It is 5.71" from the inner part of the hub to the inner lip of the rim.Say the oem rims are 7.5" wide so that leaves 1.79" Going the other way. when you subtract your backspacing from the width the number you get is the amount the wheel will stick out.
