I have a 2012 ford f150 XLT ecoboost and i just ordered this leveling kit http://www.readylift.com/c-306-new-f...t6-billet.aspx It says you can clear 35s but i have a hard time believing that. I want to put the biggest tire on i can without any fender trimming. So if anyone can give me a correct answer that would be great!

 

I run 295/70/18 Nitto Trail Grapplers on my leveled '10, and have zero rubbing and zero trimming. 35's are less than 1/2 inch taller than mine, but the 35x12.5 width might be a little too close to say you will have zero issues. It might all come down to your final choice of tire, and the degree of outside tread on the edges.

 

It's going to depend on the wheel you are using too. Factory wheels will probably be too narrow to use, so you then get into determining the proper offset and backspacing that will work with the type and size tire you want on it. I was able to run 305/55/20 Trail Grapplers on mine, but did need minor trimming on the lower plastic of the bumper. You might be able to run 305's on one style of wheel without problems, but on another style of wheel you might so you have to do some homework.

 

alright thanks i just wen with the 34's so i dont have to do any trimming

 

The wheel specs will determine what size tire you can run on a leveled truck.

 

Yea you should be fine with those, as i have a 1.5 inch level up front and am running 275/70/18 duratracs which are 33.4 and i have nowhere near any clearance issues

 

I have that same level kit and I have the 275/65/20s 34.1" It works for me.
