Ive been reading as many threads as possible but im still unsure how the offset and backspacing really works and before i buy rims and tires i was hoping for some help!!!!
I have a 2018 F150 xlt sport with a level from factory, sits almost level with back i think not off by much. I was looking at the Method wheels 312 in bronze, site says they are 18/9, bolt pattern is 6/135 or another one is 6/5.5 and the offset/spacing is 18/5.75" . I also want to try out the Nitto Ridge GrapplersLT285/70R18 E 127/124Q 217370 16.4 33.98 11.50 7.5-(8.5)-9.5 3860/3525 @80 59.94. so its almost a 34in which i like, only weighs say 60lbs. read great reviews on them. im looking for the tire to stick out a little past the side but i dont want it to sit inside at all. flush is ok but i would rather be safe and have it stick out further than not enough cause i can always get the fender flares after.
Hoping to get after market upper control arms to get that extra droop travel but i dont know anything about that like if it will work with stock suspension or do i need more parts. maybe ill do another thread on that later lol any help on this rim/tire combo is greatly appreciated!!! now time to find that thread with all the pics of the different truck and tire combos!!!

Thank you!!!!!

As far as offsets goes, I would suggest getting a +1 to -12 offset wheel , to sit just where you want it. Typically, a wheel that size has a 5.5-6" backspacing. Anything higher than that might not clear your UCA's

There is some good info here

They have another rim, the 310 / Con 6, 18/9 with a -12/4.5" would that work? Sorry i still dont really understand how all the backspacing numbers work. Would probably need someone to show me face to face a million times lol Also has anyone got any pics of Bronze rims on a black truck? im thinking it will look good

Thank you for the feed back!!! I really appreciate it!!!

I was also thinking about getting one of those after market uni uca's, from what i see they dont affect anything other than the droop travel by roughly 1-1.5in. So that shouldnt affect where the wheel sits in the wheel well at all eh? but can give better clearance for different offset?

Thank you for all the help!!!!!!!

I am running a +0 offset (I think its a 5" backspace) 20x9 wheel on my 2015 XLT 4x4. This setup leaves the perfect amount of tire outside of the fender (IMO) at a little over an inch for the front and back. Gives it a mean stance and looks aggressive. It also leave enough lip on the wheel to look good. With that in mind make sure you try to find a truck running a similar size of tire/wheel/offset to avoid rubbing and cutting. Try the gallery at customoffsets.com

Yea i dont see a whole lot with the 18in wheels. Seems 20s are a lot more popular. Would a higher number on the backspace mean it sticks out further from the fender? so like a 5.75in would be a lot sticking out and the other option is the 4.5in would hopefully be still sticking out? i just really dont want it to sit inside the wheel well and the shop here im limited to go with i dont really trust them to make the call on whats the good offset/backspacing to go with lol

Backspacing is the measurement from the back of the wheel to where the lug nut/hub attaches to your truck !!

Decided on the Ultra Motorsports 217 Warlock wheel, Dark Satin Bronze with satin black lip rims. 17x9. And im gonna throw on my 35in mickey thompson baja mtz's. i think they guy said the rim is a -16 offset or something around there, so i hope its what im looking for. Wish me luck! should be coming in by the end of the week!!!
