School me on offset and such.....
Okay, so I have a 2010 4x4 Screw and I want to get new wheels and tires. I currently have the 17in alloys and want to upgrade. A guy at the wheel shop told me a few wheels I picked out would not work because the offset was too low. Said I needed to stay around 30 and I could have lower if truck was lifted.
I might add a level kit to the front and would if needed. I want an 18in wheel and tires around 32-33in tall. Nothing extreme, just a little more aggressive look.
So, what offset do I need to say within at factory height level? Also, if I add a 2 or 2.5in level, what can I run then. Looked at numerous posts here but I only confused myself further after being at the wheel shop. Thanks all.

Factory offset should be around +32mm. When you go higher you start hitting the UCA, lower you push the wheel out and start clipping the wheel well with the outer edge of the tire.
There is a thread in the 09+ subforum about wheel/tire combos at stock height you should check out.

Maybe we can help. Here's a good link that explains offsets and backspacing:
https://www.f150forum.com/f31/offset...-relate-57501/
If you want to keep your wheels tucked within your fenders here's what we recommend for offsets:
Wheel Width ___ Offset Range
___ 6.5 _________ -1/+65
___ 7.0 _________ +6/+65
___ 7.5 _________ +12/+65
___ 8.0 _________ +18/+65
___ 8.5 _________ +25/+59
___ 9.0 _________ +31/+53
___ 9.5 _________ +37/+47
*Note, Wheels with offsets at the lower end of what is recommended above will place the wheel closer to the fenders edge. Offsets at the higher end above will tuck the wheel further under the vehicle.

Yes, an wheel that is 18x9 with an offset between 31 and 53mm will sit within the fenders. If you want them to stick out beyond the fenders any offset below 31mm on an 18x9 will stick out beyond the fenders. A lot of guys that choose 18x9's go with a 25mm offset these will stick out about 1/8-1/4" beyond the fenders (not counting the tire) giving the truck a nice wide stance without going over the top.
