3/2 Lift and OEM F150 FX4 wheels - max tire size?

[Jay444]

OEM 2016 F150 FX4 wheels on 07 - tire recommendations?

I have a 2007 Ford Expedition XLT 4WD. Stock tires are 265/70R17 (31.6" diameter).

I will be installing the Rancho Quicklifts on it. These give a 1" lift in the front and 3/4" lift in the rear.

I purchased a set of 2015/2016 OEM FX4 18x7.5 wheels. I'm not sure about offset.

The wheels come with the stock Goodyear Wrangler Fortitude HT 275/65R18 tires. I am thinking about changing out the tires for a more aggressive look.

I like the BF Goodrich All Terrain T/A KO2 - nice looking tire and rates very well.

I'm looking at the following sizes:
275/70-18 (33.2" diameter)
275/65-18 (32" diameter)

Use: I tow a 4000# boat 10-12 times a year. 1-2 long road trips a year.

Any other tire/size recommendations for my setup?

Some on here run 35's with a 3/2 but they remove the running boards and trim some of the front.

I posted a pic from instagram where the truck has a 3" lift and 35s

Thanks.

I went with the Rancho Quick Lifts, 2015 FX4 rims and BFG KO2 275/70-18 (33"). Can't put any bigger tires on these rims due to rim width (9")....

I like the way it turned out... but next time would go for a bigger lift and bigger wheels
