I have a 2017 Ford F-150 XLT stock suspension, which I like and I don't want to lift. It has stock 18 wheels with Good Year Wranglers, which are nice but I want a more aggressive look.

I am looking at some Race Line wheels"20x9
Bolt Pattern: 6x139.7 / 6x135 - Offset: +20mm.
Which after doing the reading in this forum should fit and look fine.

Wait for it, here is the question:
Looking to get Falken Wildpeak AT3W All Terrain tires.
I want 275/60/20 (33) fitment calls out 275/55/20 (31.9).

Now in this forum I have seen some of you guys running
Falken Wildpeak AT3W 275/60/20 and say no rubbing, no problem but that's
on a 20" stock rim which I believe is 20X8.5. Can I run the 275/60/20 (33)tire with absolutely no problems or should I go with the 275/55/20 (31.9) which guarantees no problem?

 

You can also go to a 305/50 20 (32) but because of the extra width I think you would need a level to run a 305/55 20 (33.2). Others will let you know about that.
I am running the 305/50 20 on my stock height FX2 with the stock 44 offset 8.5 wheels.

 

Siber Express got any pic's of what you are running, I want to see how it looks.
I may go with a stock 20X8.5 with 44 offset wheels and avoid all the headaches.

 

Now mind you I have a Stock 4X2 and I have a street tire on it.
You can see in the one without the bed how big they really are, sorry these are all I have right now since it was hit not to long after I put them on and its new garage is still at the body shop

 

Nice, I like the way they fill up the wheel well.
