I have a 2015 F150 XLT 4×4 crew cab that came with 275/65r18 wheels. Specs for the 275/65r18 is
Diameter=32.1"
Width=10.8"
Sidewall=7"
Circum.=100.7"
Revs/Mile=629

I plan on installing a 2" rough country leveling kit this weekend. I have 1" of clearance between the upper control arm and the tire now. How big of a tire can I go with using the stock 18" rim with its offset. If you have stock 18" rims with 2" leveling kit with bigger tires please post pictures for me. Don't wanna have to cut anything and no rubbing.
All recommendations are appreciated. Thanks

According to out fitment lift 2" front and rear lift kit by Tuff country for 4x4 2015 F150 allows running tires with the maximum size of 33" x 12.5"
So if you are looking toget this or similar kit th wheels with the overal diameter of 32.1 should be fine. However it also depends on the offset and backspacing of your wheels.

Plenty of people have run 295/70r18 which is 34.3 x 11.5 I believe. 33 12.5 will likely fit if running an AT. Many guys have put 35 12.5 but will likely rub bumper and inner fender. And won't have enough clearance if you off road.

Offroad? You mean leaving the pavement? No one actually goes offroad anymore... :rolleyes:

I decided on the Nitto Ridge Grappler 275/70r18 with stock 18" chrome wheels. I will be installing the rough country 2" strut leveling kit also. Hopefully no tire rubbing.
