Hey guys!
So I have an 05 5.4L XLT flareside and I'm thinking about getting a 2.5" leveling kit and putting 1" blocks in the back. My tires are 275/60R20. If I do the level do I need bigger tires, wheel spacers, or am I good?
Pics would be nice too 👌

What's up everyone? I started a thread when I first got on the site, but it didn't get much attention. So I'll bring my query here. I have an '06 F150 XLT 4x4. I am looking at putting 33x12.50s on it. Here's my issue. I'm getting conflicting advice regarding the rim, back spacing, and offset (I honestly have no idea about offset). I've had a few people tell me that 33x12.50s will fit on a stock 17x7.5" rim, but looking at some specs, it shows that I could get uneven wear in the middle of the tire, unless I run it low on air. I don't want to run it low because it'll give more resistance while driving.
So my questions become, should I go with a 16x8" rim or 17x8" rim? Should I do a 4.5" back spacing to give it a wider stance, or will that make the tire rub on the UCAs or the fender? And what in God's name does the offset do?
Thanks in advance!

This is for 2004-2008.
On a stock truck without leveling kit you can run 33X12.5" tires if it is a 4WD and 31X12.5" tires if it is a 2WD, using stock wheels.
On a leveled truck(2" kit and larger) you can run 35X12.5" tires on a 4WD and 33X12.5" tires on a 2WD truck, using the stock wheels.
Using aftermarket wheels you can run 35s on a 4WD if the wheels follow these guidelines:
-For an 8" wide wheel the backspacing is 5.5 inches.
-For and 8.5" wide wheel the backspacing needed is 5-6 inches.
-For an 9" wide wheel the backspacing is 4.5-5.5 inches.
If the wheel specs are not listed about you will more than likely have to run 33s or even smaller to avoid too much rubber and trimming. These specs are the basics for tires fitting well but you could run 35s if the specs are very similar but you will face bad rubbing.
For a 2WD truck and after market wheels you can run 33s with wheels that fit withen these specs.
-For an 8" wide wheel the backspacing is 5.5 inches.
-For and 8.5" wide wheel the backspacing needed is 5-6 inches
-For an 9" wide wheel the backspacing is 4.5-5.5 inches.
If the wheel specs are not listed about you will more than likely have to run 31s or even smaller to avoid too much rubber and trimming. These specs are the basics for tires fitting well but you could run 33s if the specs are very similar but you will face bad rubbing.
Remember that these are the basics to running aftermarket wheels and tires, certain tires might not rub but others might because of aggresive sidewalls.
These specs should work for most people and instances but if you are worried about fitment get the tire shop to mount the tire on the wheel and put it on the truck then turn the wheel to full lock in both directions to see and possible problems. If the tires you plan on running aren't 12.5 inches wide you still might be able to run 35s because of that reason, for a 4WD and some aftermarket wheels or 33s for a 2WD. It's best if you can find wheels that are a happy medium between the two backspaces for the 8.5" and 9" wheels because you will face more rubbing if you go for 6" of backspacing on a 8.5" wheel instead of 5.5 inches that's right in the middle.
For those who are curious. The stock wheels(17 and 18") are 7.5 inches wide with 5.5 inches of backspacing. The bolt pattern is 6X135mm.
Big thanks to PawPaw on this one.
If you have any instances where you find that these specs haven't worked for you please let me know and I'll make the appropriate changes, please PM so I will see it.
Hope this helps.

Just curious if you know what brand tire was being run. I was told a Terra Grappler would actually need a 8" wide rim because there will be uneven wear to the middle of the tire. Everyone I've spoken with says that I would need to run the tires with less air. I just want to be clear before I but new tires and screw them up too bad. Also, I want a wider stance from the truck, should I go with a 4.5" back spacing?
