start off by saying i have a 2009 f150screw 4x4. wanting to get 295x60rx20 nitto trail grapplers. with aftermarket wheels below.

wheel dimensions of:
20x9
offset 18mm
backspacing 5.71

will this fit with 2.5" levling kit?

 

They should fit fine with the exception of some minor trimming to the front valance. This combo will stick out about 1.5" past where the factory rims and tires did. I have 295/60r20 trail graps on 20x9 rims with +1 offset and a 2" level and had to do some minor trimming to the rear of the flare as well.

 

the post below is my final decision

 

or even this setup

toyo tires open country m/t 315/60r20
Rim dimensions 20x9
offset 18mm
backspacing 5.71
bolt pattern 6x135

 

The 315/60 is almost a 13" wide tire, and you may be trimming into fenders to get them to clear. I think you'll be happy with the 295/60.

 

the first set up you mentioned will fit easily, the second set up with the toyos will be a bit more difficult. Either way its not outrageous.

Have you seen pics of your body style on a 2.5 inch level? Most guys find it actually puts them about 0.5 inches nose high. Just in case you weren't aware..
