Sorry, another wheel question
I feel like I've read just about every wheel thread on this site but thought I would post and get confirmation. I plan on purchasing some aftermarket wheels in the next few weeks, most likely 20 inch. What backspace and offset should I be looking for if I want my tires to be flush with the fender like my stock wheels? Plan on 35's so 12.5 wide.
Thanks!
Thanks!

I am assuming that you are ordering online and not going to a tire shop? Most tire shops will know, the ones that don't would mount tires and rims and if you didn't like them, change them to ones that you did.
I don't like the roller skate look either...
BTW - as I am looking for take offs. what are you doing with your stock rims?

All Ford wheels are 8 inches or so just went through it putting a larger tires on my factory rims 325 65 18 no issues at all as far as backspacing 4 inches anymore you'll be out past the fender well and needing fender flares. My 2009 18 inch aftermarket rims stuck out about an inch and a half same size tires as the new truck had to put fender flares on. I wish I knew that factory rims can handle those big tires I would have never bought aftermarket rims nothing but vibration no matter how you try to put them on. Only the factor are Hub eccentric not relying on the lugs to hold the weight of the truck like most aftermarket wheels do. I'm sure you can find the right rims but they are expensive if I find all the information I'll post the exact numbers of the Hub Centric number and backspacing believe it's + 22

Someone posted here that in Hawaii that roller skate look is illegal. The tires have to fit within the fenders (or get fender flares)... Interesting idea. Would like to see that here ONLY because the wider than the fender tires fling rocks. As long as it doesn't impact me, I don't care what someone does with their stuff.

Factory wheels are +44 I believe.

In that case Radium could be a law violator - his tires stick out past the fenders... (just playing Radium) I thought I was the only one that uses a step ladder to get at things at the front of the bed.
Don't ever remember reading that particular law in Florida or Alaska. Granted, I don't represent that I know a ton about Alaska 's driving laws, just the basics. And since I am retired now and I typically keep my vehicles stock, not something I would be researching.

Yeah I'm surprised the state police never picked up on that 5 years of driving it they were too busy wondering if I'm overweight they love giving those tickets out. The funny part is that when I go to sell this new truck I'll probably spend $300 in plastic flares you can't believe how fast it sells a truck too young kids up here LOL. That's why I love the fact the factory rims work perfect and keep the tires under the truck where they belong handles much better too very predictable characteristics at high speed maneuvers take care
I'm a little guy that step ladder works perfect, if I didn't have to plow I would keep the truck stock height, but most of my lots are just a disaster by the time I get to them 2 foot plus need the extra clearance that and the farm work

OP, You will find that there are not many choices of offset/backspace. For a given style/diameter, there many be only 1 or 2 choices. For a given width, there may be only one... Yes you can order custom wheels (likely forged, and $1000 each)
That being said, with factory flares, you have about 4.5" from hub face to the fender.
So for a 9" wide wheel, an offset of 0 (backspace of 5) would be close to flush.
Most 10" wheels have a negative offset (stick out further), and combined with the extra wheel width will hang out about 2"
How do I know this? I measured the stock wheels before I ordered mine, and calculated exactly how far they would stick out past the fender.
Note that backspace conversion from offset includes the inner lip of 1/2". So for 0 offset case, 9" / 2 = 4.5" + 1/2" lip = 5" back space
37x12.50 on 20x9 with 0 offset (aka 5" BS)
