I have actually spent a LOT of time on that website, it's just that they all look to stick out around the same to me, some say aggressive on +20, some say slightly, and then on +1 some say aggressive, and then some say slightly aggressive. Guess I gotta do some more homework
Thats the truck owners saying its super aggressive/subtle etc etc! So take that with a grain of salt Kbrock!

I personally like the poke and am going with -12 myself. I started off with +35 offset XD's, then went with 1.5" spacers to get them around -3 offset, now I want to get rid of having to use spacers and am getting -12 offset. Although I see where you're coming from. My vote is to go with +1, but from what you've wrote I would guess you would be happier with +20. Here's a quick comparison (I think that is the stock 18" size?)
I have no problem running flares (1.5"), so I was thinking if the +20s are going to stick out a little bit, I might as well just run the +1s with the flares and call it a day.
If the +1s stick out 2.4 inches more than the OEM, and I have 1.5" flares on it, that doesn't mean that 0.9" of tire is sticking out, right? Because the tires aren't completely flush with the flares from the factory. Or am I just being paranoid and 1 inch past flares isn't going to do much to my paint. I don't drive on gravel roads nor do I take it offroading. I just finally have a scratch free truck and I'd like to keep it that way!
Sorry for all these basic questions, I've been doing my research but still can't quite figure it out haha

I found out something wierd. At 40mph with my stock 275's I must not have been reading accurately. With my new 305's I'm dead nuts on. I'm gonna take a different route home and see if 60mph is still accurate.
Has anyone else experienced this? I haven't used my SCT tp reprogram my speedo yet.

Same thing here. When I went from 275/55/20 to 275/60/20 I re-calibrated my speedo using a tuner, then compared it to a dash mounted GPS. Turns out the speedo didn't need calibrating, it must have been off a bit from day 1. Just changed tires and wheels to 305/55/20 and I'm going to call it good.

How's she goin' eh?
I'm also not sure what you mean by "set truck size to match odometer to distance traveled". What do you mean?

Set your tire size, so the odometer is accurate, your speedo may be off from the factory, but your odometer is usually more accurate. Mine was off by 2mph at 70, from factory, but the odometer was dead on.

Ordered -
American Racing AR914's 18x8.5 Rims - 5.34 Back Spacing +15mm Offset
Cooper STT Pro's 305/70/18
My Rims Arrived, Ordered the Tires I dropped off the Rims to get them mounted.
Returned a few days later to have them installed on the Truck.
Was told that they were the WRONG Bolt pattern. I checked and they were correct. Wrong Bolt Pattern...
I ordered The AR 914 in a 6x135mm, I have the Conformation Proving that I ordered the 6x135mm and it says 6x135mm.
Summit insists that I ordered the 6x139.7mm and thats what they sent. While they did send them in 6x139.7mm my paperwork shows 6x135mm.
They insist that since I ordered them I have to pay to return/replace them.
Rather tired of talking with them..
Question - I'll be reordering the Rims. Most likely NOT from them.
The Proper Rims for a F-150 are ...
American Racing AR 914 in a 18" x 8.5" with a Backspacing of 5.93" and a Offset of 30mm.
These will be Mounted on the Cooper STT Pro 305/70/18.
I'm currently Running Stock 22" Harley Rims with Nitto G2's in 285/55/22. I installed 2" Spacers to get the wheels out a little bit.
Will the AR 914's with 5.93" backspacing and 30mm offset stick out a bit or will they stick out TOO much.
I'm looking to have what I have now with the Spacers. I'll even add smaller spacers if need be I just don't want to STICK OUT more.
Here is my current set up.

I'm trying to order them, everyone is on backorder now.
Staightened out Summit, they didn't believe me until they saw the invoice.
Returned my money. Needless to say after all that I'll be looking else wear besides them.
Ordered at least 2-3 sets from other vendors, only to find out AFTER the order is placed that they are on Backorder.
The BackOrder is until Mid July, I might not be around and I'll have to wait.
I've got to go pick up my Rubber (Cooper STT Pro's) don't want those getting sold behind my back.
I'll keep updating either way...

Frankie was Great, very helpful once she saw My invoice she understood.
Chatted with a Merit and Dani both were Rude after a few minutes of Chatting they both said Thank You glad we could help. Right in the middle of a conversation then they disconnected me. About an hour later chatted to Merit on-line again still rude until I mentioned I saved our previous conversation. After that I have received a few e-mails asking if he can help me with anything. If I need anykind of assistance. Gets kind of annoying after a bit.
You were right thou going higher up definitely helped.
