Driving a 2013 F150 STX 4x4. I am planning on getting a 2" Leveling Kit, replacing my stock tires/rims with 18" XD MonsterIIs and going with 33x12.50x18 tires. I cannot figure out if i will need offset rims due to the increase in tire width. Please help! Thank you

 

You'll want a wheel with around 5-5.5" of backspacing.
