Hey everyone, I've been a Ford owner my whole life and I'm just now thinking of modifying my 04 F150. This truck is my full time work truck but I want to sexy it up a little bit. I'm looking to put on 18" Moto Metal Black 951 and 31" Nitto Terra Grapplers. Will this combo work without me lifting or leveling my truck? Thanks guys, and I'm excited to start customizing this truck!

 

welcome

we need some info on your truck 4x4 , 4x2
also what backspacing were you looking at for the wheels ?
and just an fyi most stock tire sizes on these trucks are 32''

 

it's an 04' f150 4x4 with the stock off road package. i have those stock 18" alluminum wheels with BFG rugged trail p275/65r18. i think you're right, those are basically 31". Would 20" wheels and 33" rubbers fit this truck stock?

 

Yes. I'd go with 33x12.50's on a 9 inch wide wheel with 5 to 6 inches of backspacing.

 

Your factory tires are more like 32". I wouldn't go any smaller than that.
